Application of aluminum in various industries

2018-08-10

What is the general role of aluminum in various industries?

Aeronautical materials, aluminous reaction, aluminum pots, etc.


1. aluminum can be replaced by other metal oxides by aluminum thermit process. Its alloy is light and tough, and is the structural material for making aircraft, rockets and automobiles. Pure aluminum is widely used in cables. It is widely used for making daily utensils.


2. The density of aluminum is very small, only 2.7 g/cm. Although it is soft, it can be made into various aluminum alloys, such as hard aluminum, superhard aluminum, rust-proof aluminum, cast aluminum and so on. These aluminum alloys are widely used in aircraft, automobiles, trains, ships and other manufacturing industries. In addition, space rockets, space shuttles and satellites also use large amounts of aluminum and aluminum alloys.


3. The conductivity of aluminum is second only to that of silver and copper. Although the conductivity of aluminum is only 2/3 of that of copper, the density of aluminum is only 1/3 of that of copper.


4. The oxide film on aluminum surface not only has the ability of corrosion resistance, but also has a certain degree of insulation, so aluminum has a wide range of applications in electrical manufacturing industry, wire and cable industry and radio industry.
