Aluminum/Aluminum Alloy is widely used:
Aluminum is the third most abundant metal element in the earth's crust after Oxygen and Silicon.
The density of pure aluminum is small, is about 1/3 of iron, melting point is low (660℃), aluminum is face center cubic structure, so it has high plasticity, easy to process, can be made into a variety of profiles, plates.Good corrosion resistance;But the strength of pure aluminum is very low, not suitable for structural materials.Through long-term production practice and scientific experiments, people gradually add alloying elements and use heat treatment to strengthen aluminum, which results in a series of aluminum alloys.
Aviation, construction, automotive three important industrial development, requirements material properties have unique properties of aluminium and its alloy, aluminum alloy density is low, but the intensity is high, close to or more than high-quality steel, plastic, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, the usage is second only to the steel industry.It has been widely used in aviation, aerospace, automobile, machinery manufacturing, ship aluminum alloy and chemical industry.

In the field of decoration, it can be used in lighting, furniture cabinets and building exterior walls; 
In the industrial field, it can be used for machining mechanical parts, wrapping chemical pipelines, mold manufacturing, aviation and ship manufacturing;

Typical AL Alloys : 1050, 1060, 1100, 2024, 3003, 5005, 5052, 5754, 5154, 5086, 5083, 6061, 6083, 6005A, 6082, 7075 etc
