Carbon fiber is a bit of a misnomer: the material that’s so popularly depicted on airplanes and sports cars is in fact a composite of both woven carbon strands and more rudimentary polymer bases. But what are the pros and cons of these new materials, and which one should get the edge if you’re choosing between models? What is Aluminum The key difference between aluminum and magnesium is that the aluminum is a corrosion resistant metal whereas magnesium is not. Compare the Difference Between Similar Terms. It is in the alkaline earth metal group and the 3rd period. Terms of Use and Privacy Policy: Legal. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } Moreover, it is a silvery white solid, and it is the most abundant metal in the earth crust. The rise of smartphones in the late 2000s made tempered glass—Corning’s patented Gorilla Glass in particular—a newly-considered structural material for all sorts of electronics. Due to the low density and resistance to corrosion, manufacturers use aluminum largely in automobiles and other vehicles manufacturing, construction, paints, for household items, packaging etc. Also, this metal is highly soluble in water, and reacts with water at room temperature, releasing hydrogen gas bubbles. Join 350,000 subscribers and get a daily digest of news, comics, trivia, reviews, and more. He’s covered industry events like the Consumer Electronics Show (CES) and Mobile World Congress in person. The thermal properties probably won’t be all that noticeable (since manufacturers have become quite good at managing internal heat anyway). Carbon fiber conducts heat at a fraction of the rate of either aluminum or magnesium, making it an ideal choice for areas of the laptop case where users are likely to place skin, like the palm rest. More importantly, magnesium is useful in organic reactions (Grignard reagent), and many other laboratory reactions. Since there are two electrons in the outer most orbital, magnesium likes to donate that electron to another more electronegative atom and form a +2 charge ion. Because it is a composite of the carbon weave and more fragile polymer, its finish isn’t anywhere near as durable as the woven interior—it’s much more susceptible to visible scratches and dents. Summary. In the 1980s, an engineer, Frank Kirk, devised a novel form of frame that was die cast in one piece and composed of I beams rather than tubes. The material is, at least in some ways, easier to mold and shape than metal, requiring only a simple cast mold for larger pieces rather than a machine-controlled milling process. Magnesium and aluminum are metals that have a somewhat similar appearance. 3. The key difference between aluminum and magnesium is that the aluminum is a corrosion resistant metal whereas the magnesium is not. How-To Geek is where you turn when you want experts to explain technology. Besides, the main aluminum containing mineral is bauxite. Because of this, it’s being deployed primarily as a combination material, with cases using lightweight and attractive carbon fiber on interior components like the palmrest and touchpad while using alloy metal on the exterior. Most manufacturers like to show off the carbon fiber material in their designs, resulting in a distinctive grey-and-black weave that’s instantly recognizable. If there’s an “older” option with the new generation of laptop designs, it’s aluminum. Here we can see the guidelines for the chemical composition of 6063 aluminum. It also feels pretty nice, and it’s now relatively inexpensive to integrate into a laptop’s design. Magnesium is the 12th element in the periodic table. To my knowledge, there hasn’t been a laptop body made entirely out of carbon fiber (though there have been a few smartphones made from structurally similar Kevlar). Magnesium is also less thermally conductive, meaning designers have more freedom in placing internal components that won’t create an uncomfortably hot case. Magnesium is added to increase strength, while the silicon is added to reduce the metal’s melting temperature. There are many applications of these chemical elements as metals due to their favourable properties. Magnesium and aluminum are two chemical elements that we can categorize as metals in the periodic table. The result is a material with an extremely high weight-to-strength ratio, allowing for protection similar to a metal or alloy at a fraction of the weight. It’s lighter by volume than aluminum by approximately 30% (it’s actually the lightest structurally-used metal in the world), while having a greater strength-to-weight ratio. Significant engineering needs to be employed at the design stage to keep hot zones like the processor and heatsinks away from areas where the user is likely to touch the machine for extended periods of time. Furthermore, it also reacts well with most acids and produces MgCl2 and H2 gas. The Agency will conduct a public process to identify the best ways to reduce the risks associated with aluminum and magnesium phosphide exposure. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. However, carbon fiber does have some distinct disadvantages over more conventional laptop materials. Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. It might be scratch-resistant and less likely to break than a typical window pane, but a drop onto any reasonably hard surface will still shatter screens, lids, and touchpads. Aluminum, magnesium, zinc and zinc-aluminum are the four most commonly used alloys in die casting processes across North America. Chemical Composition of 6063 Aluminum. After that, using electrolysis of magnesium chloride, we can separate the metal at the cathode. A handful of bicycle frames are made from magnesium, which has around 64% the density of aluminum. Magnesium has the electron configuration of 1s2 2s2 2p6 3s2. We can extract this metal from seawater by adding calcium hydroxide. Also, aluminium is in the mineral forms such as cryolite, beryl, garnet, etc. The atomic weight of Mg is about 24 g mol-1, and it is a lightweight metal, but strong metal. Your design’s application, material density, tensile strength, yield strength, melting temperature and modulus of elasticity are all important factors in selecting the alloy best suited to your design needs. The key difference between aluminum and magnesium is that the aluminum is a corrosion resistant metal whereas magnesium is not.. Magnesium and aluminum are two chemical elements that we can categorize as metals in the periodic table.Both are naturally occurring metals in … Moreover, Mg compounds are incorporated into food, fertilizers and culture media, since it is an essential element for the growth and development of organisms. Carbon fiber is also much more expensive to produce than even magnesium alloy. Join 350,000 subscribers and get a daily digest of news, geek trivia, and our feature articles. 5. 2. The Agency has determined that all uses of aluminum phosphide and magnesium phosphide as specified in this document require mitigation of the risks associated with the exposure to these pesticides. Full magnesium-bodied designs, like the Surface Pro and some premium entries in the HP ENVY and Lenovo ThinkPad lines, tend to be more expensive than comparable models. It has a role as an anticonvulsant, a cardiovascular drug, a calcium channel blocker, an anaesthetic, a tocolytic agent, an anti-arrhythmia drug, an analgesic and a fertilizer. Since we launched in 2006, our articles have been read more than 1 billion times. As such, its major alloying elements are magnesium and silicon. Aluminum, magnesium, carbon fiber, even the super-tough tempered Gorilla Glass—it seems that if you want to make a new high-end laptop or tablet, old-fashioned plastic just isn’t an option anymore. But they come with some fairly obvious downsides: even the relatively thick bodies of premium aluminum laptops will dent if impacted hard enough, and they’ll do so more frequently than plastics due to lack of flex in a multi-part chassis. Basically, it’s a high-tech plastic reinforced with synthetic carbon. 1. Earth's body of soil, called the pedosphere, has four important functions: . He spent five years writing for Android Police and his work has appeared on Digital Trends and Lifehacker. The above article may contain affiliate links, which help support How-To Geek. In 2024 aluminum alloy, these elemental percentages are 4.4% Cu, 1.5% Mg, and 0.6% Mn, nominally. Next-Gen Laptop Materials: Aluminum Alloy vs. Magnesium Alloy vs. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. All Rights Reserved. Therefore, naturally, we cannot find this metal as a pure element. Let’s take a look. This is has now become more or less the standard for high-end laptops. As a material for laptop and tablet bodies, tempered glass is a cosmetic addition, and not a particularly durable one. The components beneath might be nearly as safe as they are underneath metal, but a corner drop or piercing impact will still look pretty bad. To offset this, manufacturers will sometimes combine magnesium shells with cheaper plastic parts on the frame or internal areas like the palm rest. The electron configuration of Al is 1s2 2s2 2p6 3s2 3p1. Modern tempered glass is some amazing stuff, incorporating scratch resistance that’s almost as good as materials like synthetic sapphire. Magnesium, an alternative to aluminum, is used as a primary alloy for an increasing number of laptop designs. Unless you plan to constantly use a laptop in high-temperature environments, the internal specifications should probably be a more pressing concern. Carbon Fiber, How to Search for YouTube Videos by Hashtag, How to Use the TRIM Function in Microsoft Excel, How to Transfer LastPass Passwords to 1Password, How to Use Two HomePods as a Stereo Pair With the Apple TV, How to Automatically Delete Old Text Messages on iPhone or iPad, © 2021 LifeSavvy Media. Thus, it forms +3 cation while magnesium has two valence electrons and can make +2 metal cation. Aluminum is a metal having the atomic number 13 and chemical symbol Al and Magnesium is a metal having the atomic number 12 and chemical symbol Mg. Helmenstine, Anne Marie, Ph.D. “Aluminum or Aluminium?” ThoughtCo, Sep. 10, 2018. Aluminum also conducts heat much better than plastic, making some laptops prone to uncomfortable overheating. We can denote this metal as Mg. Magnesium is one of the most abundant molecules in the earth. This allows magnesium alloy electronics bodies to be thinner than similar aluminum designs with the same general durability. When we burn the free magnesium metal, it gives a characteristic sparkling white flame. Moreover, there are three valence electrons of aluminum. Anodizing, an alloy treatment that can help with heat dissipation and corrosion resistance, can also be used to “dye” aluminum different colors. PubChem Compound Database, U.S. National Library of Medicine. But, it is highly reactive with oxygen; thus, forms a magnesium oxide (MgO) layer when exposed to normal air, which is dark in colour. While manufacturing these specific parts is expensive, it allows laptops to be designed with fewer body parts overall, simplifying manufacturing as a whole and making them less prone to body warping and deformation.

Also, since this metal is too reactive to stay in its free form, naturally it occurs in mineral forms. Apart from that, aluminum does not easily ignite, but magnesium does. Overview and Key Difference The reasoning was twofold: using the anodizing process to finish and color the metal solved the paint chipping issue of previous generations, and aluminum is cheaper to buy and work with than titanium. 1. 2.”Magnesium”By Maral10 – Own work, (Public Domain) via Commons Wikimedia. Unfortunately, it’s also considerably more expensive as a metal. With increased rigidity a magnesium case might be less likely to bend or dent than an aluminum one, but it’s also more prone to crack with increased pressure. And, this MgO layer acts as a protective layer. It wasn’t until the introduction of the Macbook Air that Apple debuted its “unibody” design language, with the main body (and later the screen assembly) formed out of a single piece of machine-milled aluminum alloy. It is a magnesium salt and a metal sulfate. But be aware, tempered glass is still…well, glass. This alloy is part of the 6000 series of alloys. The iPad is made out of 100% recycled aluminum, and the Surface Pros are made out of magnesium (except for the Surface Pro X, which is made of aluminum… Aluminum alloys are typically stronger than plastics, especially when used in unibody designs. It is an essential element in macro level for plants and animals. Magnesium largely occurs in seawater and minerals like dolomite, magnesite, carnallite, talc, etc. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Available here Magnesium is a metal that has a lower density than other metals and is thus used for parts that need to be lightweight. Magnesium is generally easier to use than aluminum in terms of manufacturing, opening up new design capabilities for laptop and tablet makers. “Magnesium.” National Center for Biotechnology Information. Both are naturally occurring metals in different mineral forms. 4. Laser etching machines can be specifically configured to etch magnesium and magnesium alloys. With increased rigidity a magnesium case might be less likely to bend or dent than an aluminum one, but it’s … It has a magnesium-alloy material and a chrome Microsoft logo on the rear kickstand. However, they are two different metals. Also, it looks really cool. More differences are tabulated in the infographic on the difference between aluminum and magnesium. In addition to the fairly obvious use for touch screen laptops, some newer designs have used tempered glass for laptop lids and even premium, smooth-tracking touchpads. Michael Crider is a veteran technology journalist with a decade of experience. It forms magnesium hydroxide. It doesn’t easily ignite. As part of these next-generation designs, we’re also seeing a lot of new materials going into laptops as well. What is Magnesium 2. An additional difference between aluminum and magnesium is that the aluminum is not soluble in water at room temperature whereas magnesium is highly soluble in water, and reacts with water at room temperature. While its lower density means that aluminum shells need to be thicker, that extra stiffness generally results in a design that’s less prone to bending, warping, and denting. Between aluminum alloy and magnesium alloy, there really isn’t enough of a difference to sway a new laptop purchase one way or the other. There, we need to filter the precipitated magnesium hydroxide, and then we need to make it react with HCl to produce MgCl2 again. Aluminum or Al is an element in group 3 and period 3 and has the atomic number of 13. It is not soluble in water at room temperature. Some laptops as cheap as $300 feature aluminum body designs, though without the milled single-piece body design. Available here, 1.”2775895″by HeungSoon (CC0) via pixabay This breakdown explains why 2024 aluminum is known for its high strength because copper, magnesium, and manganese greatly increase the strength of aluminum alloys. Between aluminum alloy and magnesium alloy, there really isn’t enough of a difference to sway a new laptop purchase one way or the other. Large bauxite ores are located in Australia, Brazil, Jamaica and Guinea. With laser metal etching, part of the material is removed from the surface, creating highly contrasted black and white marks. All rights reserved. Therefore, this makes another difference between aluminum and magnesium. The key difference between aluminum and magnesium is that the aluminum is a corrosion resistant metal whereas magnesium is not. Side by Side Comparison – Aluminum vs Magnesium in Tabular Form Magnesium is a mineral that is important for normal bone structure in the body. The density of type 6061 aluminum is 2.7 g/cm 3 (0.0975 lb/in 3). Furthermore, the atomic weight of aluminum is 27 g mol-1, and it is a light weighted, durable metal. Magnesium sulfate is a magnesium salt having sulfate as the counterion. Moreover, it is a crystalline solid with a silvery colour. The main alloying elements in 6xxx series aluminum alloys are magnesium and silicon, and the elemental breakdown for 6061 aluminum is 0.6% Si, 1.0%Mg, 0.2%Cr, 0.28% Cu, and 97.9% Al (note that these numbers have allowable tolerances, and can vary with natural impurity levels). By submitting your email, you agree to the Terms of Use and Privacy Policy. Famously employed by Apple on its high-end PowerBooks way back in 2003, aluminum alloy replaced the titanium alloy of older generations. I. Shapiro (1963) established that the contact hardness (load/area of the contact flat) of freely compressed pure magnesium spheres is 32.5 kg/mm^2 (compares extremely well with the … Since manufacturers like ASUS already have huge orders for smartphone glass, why not stick a little on a laptop? We’re currently experiencing a renaissance of laptops, with both incredible specifications and some really amazing design work adorning the latest models.
