Chemical Etching with Copper

E-Fab Materials Copper Bar

Engineers call for copper when electrical and thermal conductivity is critical for successful part implementation. Copper is a reliably available metal that is easy to process and budget-friendly. Plus, it’s malleable enough to be used in many manufacturing processes to create accurate parts.

E-Fab’s copper manufacturing experience includes producing flex circuit parts, stiffeners, busbars, and micro bumps. We have a decades-long track record of supplying electronics, defense, industrial, technology, and communications industries with our precision copper parts. 

We welcome your questions about how to use copper for your parts.
