Surface Finishing Options for Copper

We offers extensive surface finishing services that enhance the aesthetic appeal, functionality, and durability of copper parts. As part of our copper CNC machining service, these surface finishes include sandblasting, tumbling, electropolishing, alodine, teflon coating, electrophoresis, painting, and more. Each finish delivers superior coatings or adds layers to enhance the appearance and improve the physical properties of machined copper parts. Some unique finishes help hide minor imperfections on copper components.

As machined:

This option leaves copper with visible tool marks from machining.

Polishing:

This option leaves copper with visible tool marks from machining.

Sand Blasting:

Sandblasting can be applied to copper to give it a matte or textured finish.

Tumbling:

Tumbling smooths and cleans up copper surfaces, leaving a matte finish.

Electropolish:

Electropolishing can enhance the surface of copper, giving it a bright, reflective finish and improving corrosion resistance.

Alodine:

Though mainly used for aluminum, Alodine can sometimes be applied to copper for light corrosion protection.

Heat Treatment:

Heat treatment can alter the appearance of copper through oxidation, giving it different colorations or surface textures.

Black Oxidize:

This process can create a darkened surface on copper, offering some protection against oxidation.

Electroless Nickel:

This finish is suitable for copper to improve wear resistance and corrosion protection.

Chrome Plating:

This process can be applied to copper for a shiny, durable surface finish.

Brushed Finish:

Brushing can give copper a textured, matte finish with fine, directional lines.

Pros and Cons of Copper CNC Machining

Copper has numerous advantages that make it well-suited for CNC machining processes. Nevertheless, it is important to consider certain drawbacks of aluminum parts machining before deciding to use it for any project.
