High-Strength 182 Copper Hex Bars

Yield Strength: 40,000 psi
Hardness: Rockwell B70 (Medium)
Temper: H04 (Full Hard)
Heat Treatable: Yes

182 copper is stronger, harder, and more wear resistant than 110 copper. Also known as RWMA Class 2 chromium copper, it's commonly used in resistance welding, for circuit-breaker parts, and for molds to make plastic parts.
