Copper C110
Copper C110 (ETP) – Electrolytic Tough Pitch Copper for Electrical Conductors
Copper C110 is electrolytic tough pitch (ETP) copper, the most commonly used electrical copper grade at 99.9% purity and 100% IACS conductivity. It is the industry standard for bus bars, electrical wire, heat exchangers, and general electrical conductors where maximum conductivity combined with good formability is required at economical cost.
