Copper 101 Product Guide

Applications | Specifications | Mechanical and Chemical Data | Tolerances

Overview

A commercially pure high conductivity grade of copper that has no oxygen, giving it excellent electrical and thermal conductivity. The lack of oxygen gives 101 immunity to hydrogen embrittlement at elevated temperatures. It is excellent for hot working, cold working, and forging. 101 can also be soldered, brazed, and welded easily. It's typically used in conductors and particle accelerators.
