Copper Alloy Die Casting
The melting point of copper alloy is relatively high, which is not conducive to die-casting from this point of view. However, due to the die-casting process of copper alloy, more complex geometric shapes can be achieved. Moreover, the copper alloy material's unit price exceeds subtractive manufacturing processes such as CNC machining. Die casting of copper alloys can significantly reduce the cost of producing complex parts.
What Is Die Cast Magnesium Alloy?
Die-cast copper alloys have high thermal conductivity, high electrical conductivity, and excellent corrosion resistance. Although the melting point of copper alloy is high, it can still meet the necessary conditions for die casting. The die-casting principle of aluminum alloy and zinc alloy is the same. The die-casting of copper alloy can create more complex geometric shapes.
Copper alloy die castings are widely used, such as radiators commonly used in the telecommunications industry, electrodes and electric shocks in consumer electronics, Etc. It can also be used for pumps, valves, propellers, and other components in water conservancy, energy, and marine industries.

Function of Chemical Components
Lead (Pb):
While lead is now used cautiously due to environmental concerns, it was added to copper alloys to improve machinability significantly. It was precious in precision casting for components in Power Tools and Locking Systems. It reduced tool wear and enabled precise machining of intricate parts.
Tin (Sn):
Tin enhances the alloy's mechanical properties, increasing its strength, hardness, and wear resistance. In the Aerospace industry, where high-stress components are standard, copper alloys with added tin can ensure that parts remain durable and reliable under demanding conditions. Tin can also benefit precision casting in the Medical Devices sector, where component wear can be critical.
Zinc (Zn):
The addition of zinc enhances the corrosion resistance of copper alloys. This property is invaluable in the Automotive industry, where parts are exposed to harsh weather conditions and road salts. The increased resistance to corrosion ensures the longevity of components in these applications.
Other Elements:
Including elements like aluminum and silicon are tailored to meet specific requirements. For example, adding aluminum enhances the alloy's resistance to high temperatures, making it suitable for E-Mobility applications, where components can experience elevated heat. Silicon can improve the alloy's fluidity during casting, a critical factor in achieving precise and intricate sheet metal fabrication for specialized parts in the Energy sector.
