Ultra-Formable 260 Brass Hex Tubes

Yield Strength: Not Rated
Hardness: Not Rated
Temper: H02 (1/2 Hard) to H03 (3/4 Hard)
Heat Treatable: No
Specifications Met: ASTM B135

The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. Sometimes called cartridge brass, it's commonly used for ammunition casings, radiator components, and decorative door hardware.

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.
