Copper
The conductivity choice for heat transfer, power distribution and RF components.
01 · QUICK ANSWER
When should you choose Copper?
Use C110 for common electrical and thermal parts, C101 when higher purity is required, and chromium copper when strength and wear must improve without losing too much conductivity.
02 · SELECTION DATA
