Alloy Material: Aluminum Alloy

Metals include pure metals and their alloys.

Pure metal refers to metal that does not contain other impurities or other metal components. It has the advantages of high electrical conductivity, thermal conductivity and good plasticity, but due to its performance limitations, it cannot meet the requirements of various occasions.

Smelting pure metal is difficult and expensive, so various alloys are mainly used in production.

An alloy is a substance with metallic properties synthesized by a certain method from two or more metals and metals or non-metals. It is generally obtained by melting into a uniform liquid and then solidifying. The alloy is harder than any of the metals it is composed of, has a lower melting point than any of them, has good thermal conductivity, and can also conduct electricity.

Alloys can complement each other in metal properties and are used more widely. For example: aluminum alloy.

Aluminum alloy is an alloy based on aluminum with other alloying elements such as copper, silicon, magnesium, zinc, manganese, nickel, iron, titanium, chromium, lithium, etc. 

The density of aluminum alloy is low, which varies depending on the alloying elements added. It is generally 2.5~2.886.6~6.7×10kg/m. 

Aluminum alloy has relatively high strength, close to or exceeding high-quality steel; it has good plasticity and can be processed into various profiles. At the same time, aluminum alloy also has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, such as used as stressed components, decoration and thermal insulation materials. Its usage is second only to steel.
