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.
