Super-Conductive 101 Copper Rods and Discs

Yield Strength: Not Rated
Hardness: See table
Temper:
6" dia. rods and discs: Not Rated
All other sizes: H04 (Full Hard)
Heat Treatable: No
Specifications Met: See table

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 ORDER HISTORY after your order ships.

Titanium-Clad Super-Conductive 101 Copper Rods

Yield Strength: Not Rated
Hardness: Not Rated
Temper Rating: Not Rated
Heat Treatable: No

A thin layer of titanium is bonded to these copper rods for long life and dimensional stability in corrosive environments. With greater than 99.9% copper content, 101 copper has higher purity than 110 copper, resulting in superior electrical conductivity. It's commonly called OFHC copper. Use these rods in electrical applications.
