About Copper
Exceptional electrical and thermal conductivity with machining behavior that rewards careful heat and burr control.
Copper is selected when conductivity is central to the design. Pure grades maximize electrical and thermal performance, while free-machining copper alloys can improve production efficiency.
Because copper is soft and ductile, machining strategy should manage built-up edge, burr formation, thin features, and heat input.
The Most Common Grades of Copper for CNC Machining
Balance conductivity, purity, machinability, and finishing requirements.
Material choices for drawing review
The selected grade should be reviewed with stock form, condition, certification, machining sequence, finishing, and service environment.
Comparison of Common Copper Alloys
Early selection guidance for pure and free-machining copper grades.
Final selection should be confirmed against the drawing, service environment, stock condition, finish, and documentation requirements.
The Challenges in Copper CNC Machining
Ductility, built-up edge, heat, burrs, and flexible features require disciplined process planning.
Use sharp tools and controlled cutting parameters to limit smearing.
Support thin sections to prevent bending during clamping.
Specify burr limits on electrical and sealing edges.
Protect contact surfaces during plating, handling, and shipping.
Protect electrical and sealing surfaces from the start
Define burr limits, contact surfaces, plating, packaging, and inspection before production.

CNC Machining Copper FAQs
Questions about grades, conductivity, burrs, and plating.
Which copper grade has the highest conductivity?
Oxygen-free C101 is selected for very high conductivity and purity requirements.
Why is copper harder to machine than brass?
Pure copper is softer and more ductile, which can increase burrs, heat, and built-up edge.
Can copper parts be plated?
Yes. Tin, nickel, and silver plating are commonly considered for protection, solderability, or contact performance.
