Application of aluminum alloy

Aluminum-based alloys The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the minor alloying elements are nickel, iron, titanium, chromium, lithium and so on. Aluminum alloy is the most widely used non-ferrous structural materials in the industry, and has been widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industries. Aluminum alloy density is low, but the strength is relatively high, close to or more than high-quality steel, good plasticity, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the use of second only to steel.

Aluminum alloy according to its properties and applications can be divided into ordinary aluminum alloy, ultra-high strength aluminum alloy, heat-resistant aluminum alloy, aluminum matrix composite materials. Its application fields have different focuses, covering all application fields of aluminum alloy.
