About Copper, Brass, and Bronze

Ultra-Formable 260 Brass Sheets and Strips

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 Ultra-Formable 260 Brass Sheets

One side of these sheets has a brushed finish with grain lines running in one direction to mask fingerprints.

Mirror-Like Ultra-Formable 260 Brass Sheets

Polished on one side to a reflective, mirror-like finish.

Ultra-Formable 260 Brass Rods

Brushed Weldable Marine-Grade 464 Brass Sheets

One side of these sheets has a brushed finish with grain lines running in one direction to mask fingerprints.

Mirror-Like Weldable Marine-Grade 464 Brass Sheets

Polished on one side to a reflective, mirror-like finish.

Easy-to-Form 220 Bronze

Offering excellent formability, 220 bronze is known for its ability to withstand outdoor exposure. It's commonly called commercial bronze.

Copper

Multipurpose 110 Copper Sheets and Bars

Offering high electrical conductivity and formability, 110 copper is 99.9% pure. Also known as ETP copper, it's often used in electrical applications, such as for bus bars and wire connectors, as well as for flashing, gaskets, and rivets.

Brushed Multipurpose 110 Copper Sheets

One side of these sheets has a brushed finish with grain lines running in one direction to mask fingerprints.

Mirror-Like Multipurpose 110 Copper Sheets

Polished on one side to a reflective, mirror-like finish.

Super-Conductive 101 Copper Sheets and Bars

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.
