Discover the top advantages of aluminum, from its lightweight properties to its corrosion resistance and recyclability. Learn why aluminum is the preferred choice for various industries.
Aluminum is a silver-white metal, quite soft, very light and can conduct electricity and heat well. Aluminum is non-toxic and has very good wear resistance. Therefore, compared to other metals, aluminum is widely used in life and in popular industries, especially in the automobile manufacturing industry. Aluminum metal is highly reflective as well as has great thermal and electrical properties. Aluminum is a non-toxic and wear-resistant metal. Aluminum is also a metal with many components in it.
Basic properties and characteristics of Aluminum
– One of the most outstanding properties of aluminum is that it is a lightweight metal: Compared to steel, aluminum weighs only ⅓ of the weight. This will explain why aluminum is always widely used in industries manufacturing equipment that requires weight concerns such as doors, aircraft, aerial components, and machinery.
– Aluminum can conduct electricity: Although it is less conductive than copper, aluminum is commonly used when used to transmit the same current.
– Aluminum is flexible: Flexibility makes it convenient to produce products in the form of plates, sheets, tape or melt-formed bars such as door frames. Aluminum door frames of all types are very popular on the market today.
Classification of aluminum
When making aluminum, manufacturers usually add alloying elements (such as Cu, Mn, Mg, Si, Sn, Zn) to improve some properties of aluminum. However, based on the method of manufacture and use, we divide them into two main groups, which are: Wrought aluminum alloy, and Cast Aluminum alloy.
a. Wrought aluminum alloy
Cast aluminum alloys are made by melting bauxite ore in a furnace, then pure aluminum is separated and poured into a mold along with the alloying element to create the desired casting, this process Quite complicated and energy consuming.
b. Cast Aluminum alloy
Forged aluminum alloys are made by melting aluminum ingots with alloying elements, then casting them into large sheets before rolling, forging or drawing into billets of various shapes. Here, cast aluminum alloys often contain more alloying elements, lower melting temperatures, and lower durability than wrought aluminum because all defects cannot be eliminated when casting. Therefore, in fact about 85% of the alloys used are wrought aluminum alloys.
Application of aluminum materials
Durability, lightness, heat resistance and good corrosion resistance are properties that help aluminum be applied in many different fields and become one of the most important materials in modern society. You can easily see the applications of aluminum in houses, cars, trains, airplanes, computers, phones, refrigerators… Join Dinostar Aluminum to learn about the applications of aluminum in 8 common industries. variable with the following article.
a. Application in construction industry
– Thanks to its high aesthetics, light weight, good bearing capacity, durability and adaptability to all environmental conditions, including harsh environments, aluminum metal is widely used in the construction and architecture industries bamboo.
– In construction projects, aluminum is used to make doors, windows, glass walls, railings, sunshades, facades, partitions, awnings, aluminum ceilings, structural aluminum frames, etc. because metal can Anti-corrosion and helps save energy.
– In particular, aluminum is also considered the material of the future because it is 100% recyclable and helps significantly reduce CO2 emissions into the environment.
b. Application in mechanical manufacturing industry
– With good machinability and no rust, aluminum is commonly used in the mechanical manufacturing industry. Aluminum is used to produce: machine components, components in household and industrial electrical equipment, smart electronic devices, CPU heatsinks, computer cases, production of phone billets and parts. details inside or in packaging technology such as cans, wrapping paper…
– In addition, with its good ability to absorb radiation, aluminum is also used to produce the outer covering of artificial satellites. Aluminum is also stronger than plastic, lighter than steel and can absorb and dissipate heat well, so many manufacturers use it in modern flat screen TVs.
c. Applications in the transportation industry
– The transportation industry cannot ignore the use of aluminum metal in its operations. With its durable and lightweight properties, aluminum is used in making parts for cars, trains, ships, and airplanes.
Automobile industry: According to calculations, 1kg of aluminum used in cars reduces the overall weight of the vehicle. Possessing this advantage, many car parts are made of aluminum such as: engine radiator, wheels, suspension system, gearbox, body, hood, car doors, exhaust system, etc. engine cylinder, chassis.
– In addition, good bearing capacity, no deformation or warping, helping to ensure the safety of car internal components is another reason why manufacturers increasingly rely on aluminum.
Rail transport industry: High-speed rail systems are using a lot of aluminum metal. With its lightweight properties, trains using aluminum will weigh less, thereby helping to reduce friction, making the train’s speed faster. A prominent example is the TGV high-speed rail system in France, which has chosen aluminum in its construction.
– Aviation industry: According to calculations, in the total weight of an aircraft, aluminum accounts for 75 – 80%. Hydraulic systems, fueling parts, engine turbines, exhaust pipes, cabin pillars, control chambers, seat frames, decorative details… are parts on aircraft that use aluminum.
Space industry: Accounting for 50 – 90% of the total weight of spacecraft, aluminum material is mainly used in many parts of space shuttles, space telescopes, fuel tanks, rocket heads, and stations. space,…
Outstanding durability in all high/low temperature conditions and in strong vibration conditions is the reason why aluminum is used in the production of aerospace industry parts.
– Marine transportation industry: The corrosion resistance of aluminum is 100 times higher than that of steel. Besides, marine aluminum also has outstanding durability, so if there is a strong collision, it is unlikely to break the ship’s hull. Thereby increasing the lifespan, safety and saving a lot of costs for ship maintenance.
d. Application of aluminum and aluminum alloys in the energy industry
