Copper for CNC Machining | Million Bright CNC

When to Use Copper

Copper is chosen when conductivity matters. It is common in electrical connectors, busbars, thermal components, and parts where heat dissipation is critical. Copper can be machined well, but it may require careful chip control and clean handling for cosmetic expectations.

Common Uses

Busbars and electrical connectors
Thermal blocks and heat transfer parts
RF and grounding components
Prototype electrical assemblies

Pros

Excellent thermal and electrical conductivity
Good machinability with the right tooling
Can support functional plating requirements

Cons

Soft material can scratch easily
Oxidation/tarnish can change appearance over time
Cost can be higher than aluminum

Machining Tips

Define cosmetic requirements and handling expectations
Plan plating thickness if required for conductivity or corrosion
Specify flatness and mating surface requirements for busbars
Consider edge breaks for safe handling

Recommended Finishes

Plating is often used for conductivity and corrosion protection depending on application.
