What strength grade aluminum alloy has?
Aluminum alloy aluminum-based alloy general. The main alloying elements are copper, silicon, magnesium, zinc, manganese, minor alloying elements are nickel, iron, titanium, chromium, lithium. Aluminum density is low, but the intensity is relatively high, close to or more than high quality steel, plastic, it can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, usage after the steel .
Aluminum alloy commonly used elements copper, zinc, manganese, silicon, magnesium and the like, the early 20th century invention by the German Alfred Wilm, greatly helped the development of the aircraft, after World War I German aluminum components are classified as state secrets.
Compared with ordinary carbon steel is lighter and corrosion performance, but not as good corrosion resistance of aluminum. Protective oxide layer in a clean, dry environment aluminum alloy formed on the surface.
