What type of copper is most suitable for CNC machining?
Copper alloys are preferred in various electrical applications, including bus bars and wire connectors, due to their excellent electrical and thermal conductivity. The high purity of 101 copper ensures superior conductivity, while 110 copper is generally more cost-effective as it is easier to CNC machine. Copper beryllium (CuBe) offers a unique combination of high strength, non-magnetic properties, and non-sparking qualities, making it an excellent choice for CNC machining, forming, and general metalworking.
What are the main material properties of copper?
Copper has good thermal conductivity, electrical conductivity, and ductility. It also exhibits good corrosion resistance and weldability, making it widely used in machining processes.
Is machining copper challenging?
Machining pure copper in CNC processes can present significant challenges and requires specialized expertise due to its properties. However, improving machinability becomes more feasible by alloying copper with elements such as tin, silicon, zinc, aluminum, and nickel. This alteration of the material composition enhances machinability, making it more suitable for CNC machining operations.
