C110 (OFE) is the purest grade of oxygen-free copper. It contains 99.99% copper and has much tighter limits on impurities than other grades. C110 offers the highest electrical and thermal conductivity values available from a commercially available copper alloy and is not susceptible to embrittlement when heated.

Specified for electronic applications requiring freedom from harmful impurities and oxide which can impair and contaminate the electronic device, C110 also has high ductility and is readily cold worked.
