Because copper, zinc, aluminum, and aluminum alloys possess excellent fluidity and plasticity, and because casting is performed under pressure in a die-casting machine.
Aluminum die castings can be produced in various complex shapes with high precision and surface finish. This significantly reduces the amount of machining required and the casting allowance for copper, zinc, aluminum, or aluminum alloys, saving not only electricity and metal materials but also substantial labor costs. Furthermore, copper, zinc, aluminum, and aluminum alloys have excellent thermal conductivity, low specific gravity, and high machinability. Therefore, die castings are widely used in various industries, including automobile manufacturing, internal combustion engine production, motorcycle manufacturing, electric motor manufacturing, oil pump manufacturing, transmission machinery manufacturing, precision instruments, landscaping, power construction, and architectural decoration.
