Silver-bearing oxygen-free copper
10AOFC
C10700
- High Heat Resistance & High Conductivity
A high-purity copper alloy based on oxygen-free copper (C10200) with a trace addition of silver (Ag).
It maintains electrical and thermal conductivity equivalent to oxygen-free copper while resisting softening at high temperatures.

Main features
- It has conductivity equivalent to oxygen-free copper (100%IACS or more).
- Ag trace addition suppresses softening and recrystallization in high-temperature ranges.
- Its oxygen content is extremely low, making it resistant to hydrogen embrittlement.
- Its formability, brazability, and weldability are comparable to those of oxygen-free copper.
