Rapid Prototyping for Copper C110 (ETP Copper)

Copper rapid prototyping is used for thermal and electrical validation where conductivity testing requires the actual production material.

Expert Machining Tips

1

Sharp tooling essential for good finish

2

Challenging to machine — allow extra lead time

3

Specify if high-purity C101 is needed vs standard C110

Common Parts Made

Heat sink prototypes

Bus bar validation

Electrical contact prototypes

Machining Challenges

  • Gummy material — surface finish may need extra passes
  • Tarnishes quickly — may need protective coating
