The main characteristics of CNC processing copper parts compared with other metals are:

● CNC processing copper parts have high electrical and thermal conductivity, (copper's electrical and thermal conductivity is second only to silver, ranking second, but the price is much lower than gold and silver)

● CNC copper parts have corrosion resistance and strong structure

● CNC processing copper parts with appropriate strength, good plasticity

● Copper parts in CNC machining are easy to process and have elegant and solemn color

● Copper parts can be plated very well

After the surface protection treatment of CNC machined copper parts, it can maintain a bright appearance and corrosion resistance and oxidation resistance for a long time. Commonly used copper parts surface treatment processes are as follows:

1) Bright cleaning of copper parts

2) Passivation of copper parts

3) Anodizing of copper parts

4) CNC processing copper parts for electroplating (galvanizing, nickel plating, chromium plating)

5) Chemical polishing of copper components
