Al-Cu type alloy is the earliest used cast aluminum alloy in industry. Its main characteristics are high mechanical properties at room temperature and high temperature, simple casting process, good machinability and excellent heat resistance. It is the foundation of developing Cu containing high strength aluminum alloy and various heat-resistant alloys. The disadvantage is that the casting property of the solid solution type alloy is poor, the corrosion resistance of the copper rich is low, and the density is larger.
Hard alloy, the melting point is 640 DEG C, is generally composed of 97% copper and 3% aluminum. Similar to the chemical properties of metal aluminum. Light and tensile strength is large. Instead of expensive copper wires.
Al Cu Aluminum Alloy can be made into plates, forgings, profiles, wire, bar, pipe, foil, aerospace structures, mechanical processing, welding solder, engine piston wheel and so on.
