Die-Casting Aluminum Characteristic: Because the metal copper, zinc, aluminum and aluminum alloy have good fluidity and plasticity, and the casting process is cast in the pressure die casting machine, so the aluminum die casting can make a variety of more complex shapes, but also can make a higher precision and finish, thus greatly reducing the amount of mechanical processing of the casting and the casting allowance of metal copper, zinc, aluminum or aluminum alloy, which not only improves the quality of the casting As a result, die casting is widely used in automobile manufacturing because of its excellent thermal conductivity, small specific gravity and high machinabilityBecause the metal copper, zinc, aluminum and aluminum alloy have good fluidity and plasticity, and the casting process is cast in the pressure die casting machine, so the aluminum die casting can make a variety of more complex shapes, but also can make a higher precision and finish, thus greatly reducing the amount of mechanical processing of the casting and the casting allowance of metal copper, zinc, aluminum or aluminum alloy, which not only improves the quality of the casting As a result, die casting is widely used in LED Street Light, LED Flood Light, High Mast Light, Solar Street Lamp manufacturing because of its excellent thermal conductivity, small specific gravity and high machinability
