High-conductivity ETP copper plate and sheet for busbars, electrodes, grounding and heat dissipation systems.
C11000 copper plate is rolled from electrolytic tough pitch copper with 99.90% minimum purity. It offers the best combination of electrical and thermal conductivity with good flatness and machinability, and is the workhorse material for electrical distribution, welding fixtures and industrial heat transfer.
