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, widely used on industry, usage is second only to the steel. Aluminum alloy is divided into two categories: cast aluminum alloy, used in cast;The deformation aluminum alloy can withstand the pressure processing, the mechanical performance is higher than the casting state.Can be processed into various forms, specifications of aluminum alloy.Mainly used for making aviation equipment, daily necessities, building doors and Windows, etc.
