Aluminum alloy chemical composition

For aluminum base alloy. Main alloying elements are copper, silicon, magnesium, zinc, manganese, secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc. 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. Aluminium alloy is divided into two broad categories: casting aluminum alloy, under the as-cast use; Machining deformation of aluminum alloy, can withstand the pressure, mechanical performance is higher than the as-cast. Can be processed into various forms and specifications of the aluminum alloy material. Mainly used in the manufacture of aviation supplies, daily necessities, building doors and Windows, etc. Aluminum alloy according to processing methods can be divided into deformation aluminium alloy and casting aluminum alloy, heat treatment deformation of aluminum alloy is divided into an improved type aluminum alloy and heat treatment strengthening type aluminum alloy. An enhanced by heat treatment to improve mechanical properties, heat treatment can only be done by cold deformation strengthening
