About Copper, Brass, and Bronze

With 99.99% copper content, 101 copper has higher purity than 110 copper, resulting in superior electrical conductivity. It's commonly called OFE and OFHC copper. Use it in electrical applications, such as for coaxial cables and terminal lugs.

Certificates with a traceable lot number are available for these products. Download certificates from ACTIVITY after your order ships.
