Surface Finishes For CNC Copper Parts
CNC machined copper parts can be finished with various surface treatments to enhance their appearance, functionality, or durability. Here’s a simple description of common surface finishes for CNC copper parts:
The easiest copper to machine is generally recognized as Copper 110, also known as Electrolytic Tough Pitch (ETP) Copper. It has a 100% IACS conductivity, is very ductile, and not as hard as other copper alloys, making it easier to cut and shape using CNC machining methods. This makes Copper 110 a popular choice in industries requiring high precision and easy machinability.
