C101

C101 electrolytic tough pitch (ETP) copper is a commercially pure high conductivity grade of copper. It has a nominal conductivity of 100% IACS (International Annealed Copper Standard) and a high thermal conductivity, making it the material of choice for use in conductors and electrical components.

C101 is refined by electrolytic deposition and then melted and oxidised to the "tough pitch" condition with a controlled low oxygen content. This is the normal grade for general electrical use as busbar, motor and transformer components, windings and many other current carrying applications. Due to oxygen present in the form of Cu2O, this copper is susceptible to hydrogen embrittlement in reducing gases at elevated temperatures. The grade also carries the risk of embrittlement when heating, welding or brazing using an oxy-fuel gas flame.
