Copper Machined Parts: Characteristics and Surface Treatment of Copper CNC Machined Parts

VMT CNC machining products include mobile phone case processing, cavity hardware processing, complex surface metal processing, etc., security/communication electronics/industrial metal casings, internal structural parts; bicycle parts; LED radiators; medical parts, etc. Among them, CNC machining copper parts is relatively common. The copper materials used in CNC machining mainly refer to copper element and various alloys of copper, including brass, bronze, red copper (pure copper), red copper, cupronickel, etc. Among them, yellow Copper is the most commonly used CNC machining material.

What are the characteristics of copper CNC machining parts:

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

● Copper CNC machining 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)

● Copper CNC machined parts have corrosion resistance and firm structure

●Copper CNC machining parts have suitable strength and good ductility

● Copper parts in CNC machining are easy to form and have elegant and solemn colors

● Excellent platability of copper CNC machining parts

After the surface protection treatment of copper CNC machined parts can keep them bright as new appearance and corrosion resistance and oxidation resistance for a long time, what kind of surface treatment is usually required for VMT copper CNC machined parts? Commonly used copper CNC machining parts surface treatment processes are as follows:

1) Perform bright cleaning

2) Passivation

3) Anodizing

4) Electroplating (Zinc, Nickel, Chrome)

5) Chemical polishing

Some friends will encounter such a problem when CNC machining copper materials: the stamped copper CNC machining parts are not cleaned, they are placed for a week and then cleaned, and it is found that black oxides will be produced on the surface of some products.

If it is the problem of the copper material itself, it is difficult to solve it from the process. It can only be processed for the blackened product. The method is relatively simple, that is, polishing the copper CNC machining parts.

The purpose of polishing copper CNC machining parts is to restore the original color and luster to the blackened surface.
