Aluminum Alloy

Aluminum or Aluminium Alloys

Aluminum Alloy is one of the most widely used non-ferrous metal structural materials in the industry and has been widely used in aviation, aerospace, automotive, machinery manufacturing, marine and chemical industries. With the rapid development of the industrial economy, the demand for aluminum alloy welded structural parts is increasing, and the research on the weldability of aluminum alloys is also deepened. Aluminum alloys are currently the most widely used alloys. The addition of elements to the aluminum gives the alloy improved strength, workability, corrosion resistance, electrical conductivity, and/or density, compared with the pure metallic element. Aluminum alloys tend to be lightweight and corrosion resistant.

Physical and chemical properties

The aluminum alloy has low density, but high strength, close to or exceeds high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance. The density of pure aluminum is small (=2.7g/cm 3 ), about 1/3 of iron, low melting point (660℃).
