The use of aluminum in various industries

Time2021.05.29

  Aluminum has a good performance in all walks of life, so what industries are they mainly used in?

1, aerospace and transportation industry: aluminum density is very small, although it is relatively soft, but can be made into a variety of aluminum alloy, such as hard aluminum, super hard aluminum, rust resistant aluminum, cast aluminum and so on. These aluminum alloys are widely used in aircraft, automobile, train, ship and other manufacturing industries. In addition, space rockets, space shuttles, artificial satellites also use a large amount of aluminum and its aluminum alloy.

2, packaging with aluminum: all-aluminum can can material is a measure of a national aluminum processing level of the symbol of aluminum mainly in the form of sheet and foil as a metal packaging material, made into cans, caps, bottles, barrels, packaging foil. Widely used in beverage, food, cosmetics, drugs, cigarettes, industrial products packaging.

3, wire and cable industry: the conductivity of aluminum is second only to silver, copper and gold, although its conductivity is only 2/3 of copper, but the density is only 1/3 of copper, so the transmission of the same amount of electricity, the quality of aluminum wire is only half of copper wire. The oxide film on the surface of aluminum not only has the ability of corrosion resistance, but also has a certain insulation, so aluminum has a wide range of uses in electrical manufacturing industry, radio industry.

4, building decoration aluminum: aluminum profile because of good corrosion resistance, enough strength, excellent process performance and welding performance, widely used in building frame, doors and Windows, ceiling, decorative surface, etc.

5, aluminum combustion in oxygen can emit a lot of heat and dazzling light, often used in the manufacture of explosive mixtures, such as ammonium aluminum explosives, combustion mixtures (such as thermite bombs and shells can be used to attack targets that are difficult to fire or tanks, artillery, etc.) and lighting mixtures.

6, thermite is commonly used to smelt refractory metals and welding rails, as well as in the process of steelmaking deoxidizer. Aluminium powder and graphite, titanium dioxide (or other high melting point metal oxides) according to a certain ratio of uniform mixing, coated on the metal, calcined at high temperature to produce high temperature resistant cermet, it has important applications in rocket and missile technology.

7, low temperature resistance, aluminum at low temperature, its strength but increase without brittleness, so it is ideal for cryogenic device materials, such as cold storage, freezer, Antarctic snow vehicles, hydrogen oxide production device.
