The main characteristics of CNC machining copper parts compared with other metals are:
● CNC machined copper parts have high electrical conductivity and high thermal conductivity, (the electrical and thermal conductivity of copper is second only to silver, but the price is much lower than that of gold and silver)
● CNC machined copper parts have corrosion resistance and firm structure
● CNC machined copper parts have suitable strength and good ductility
● In CNC machining, copper parts are easy to form and have elegant and solemn colors
● Excellent palatability of copper parts
After the surface protection treatment of CNC machined copper parts can keep them bright a new appearance and corrosion resistance and oxidation resistance for a long time, what kind of surface treatment is usually carried out for CNC machined copper parts? 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 machining copper parts for electroplating (galvanizing, nickel plating, chrome plating) treatment
5) Chemical polishing of copper parts
This problem is usually encountered when CNC machining copper materials: the stamped copper products are not cleaned, and after being placed for a week, they have cleaned again, and black oxides are found on the surface of some products. If it is the problem of the material of the copper itself, it is difficult to solve it from the process. It can only be processed for blackened products. The method is also relatively simple, that is, polishing the copper parts. The purpose of copper polishing is to restore the original color and luster to the blackened surface.
Which industries are CNC machining custom copper products suitable for?
Copper CNC machining parts are often used in electric power, home appliances, construction, automotive industry, and industrial gears, and the good appearance makes copper parts very popular in home accessories.
