C10200 Copper Oxygen-Free Electronic (OFE) Copper

Nov 28, 2025

What is a C10200 copper ?

In simple terms, C10200 is a very pure, high-conductivity copper known for its exceptional ductility, corrosion resistance, and thermal conductivity. Its most defining characteristic is its extremely low oxygen content, which gives it the common name Oxygen-Free Electronic (OFE) Copper.

The "C10200" designation comes from the Unified Numbering System (UNS), which is a standardized system for naming metals and alloys in North America.
