Aluminum alloy Precision Casting ANSI 852.0

Aluminum alloy Precision Casting ANSI 852.0

 
Alloy Base on aluminum. Main alloy elements are copper, silicon, magnesium,zinc,manganese, minor alloy elements are nickel, iron, titanium, chromium, lithium, etc.Aluminum alloy is the most widely used non-ferrous metal structural materials in industry , and have been extensively used in the aviation,spaceflight,automobile, machinery manufacturing, shipping and chemical industry.Aluminum alloy density is low, but the intensity is high, close to or more than high-quality steel, plasticity good, can be processed into various shaped materials, has good electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, usage is second only to the steel.
