About Copper, Brass, and Bronze

Yield Strength: 40,000 psi
Hardness: Rockwell B45 (Soft)
Temper: H01 (1/4 Hard)
Heat Treatable: No
Specifications Met: ASTM B134, ASTM B36

One side of these sheets has a brushed finish with grain lines running in one direction to mask fingerprints. The brushed side comes covered with a protective peel-off film. 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.

Brushed Weldable Marine-Grade 464 Brass Sheets

Yield Strength: 58,000 psi
Hardness: Rockwell B80 (Medium)
Temper: H01 (1/4 Hard)
Heat Treatable: No
Specifications Met: ASTM B171

One side of these sheets has a brushed finish with grain lines running in one direction to mask fingerprints. The brushed side comes covered with a protective peel-off film. A lead-free alternative to 485 brass, 464 brass offers good weldability, strength, and wear resistance. It’s widely used for marine hardware, pump and propeller shafts, and rivets.
