CNC Machine for Copper

Copper is a versatile and widely used metal known for its excellent electrical and thermal conductivity. It's a reddish-brown element with the chemical symbol Cu and atomic number 29 on the periodic table. Commercially available copper is typically more than 99% pure. The remaining 1% is usually impurities such as oxygen, lead, or silver.

For CNC machining purposes, Copper's outstanding electrical and thermal conductivity makes it an excellent choice for precision components and parts, especially those requiring good electrical or thermal conductivity. CNC machining of copper allows for the creation of intricate designs and shapes that cater to specific industrial needs.

Finishes and Post-Processing Options

When selecting the best finish option for your copper parts, consider factors such as the intended use, aesthetics, maintenance requirements, and the level of protection needed.

Polishing: Polishing copper to a high shine creates a luxurious and reflective surface. This finish is often used for decorative items, jewelry, and high-end products where aesthetics play a significant role.

Electroplating: Copper parts can be electroplated with various metals, such as nickel or chromium, help prevent oxidation of its outer surface while maintaining electrical and thermal conductivity. This can also provide a wide range of color options.
