About Copper, Brass, and Bronze

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.

260 Brass Balls

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.

Ultra-Formable 260 Brass Wire

The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. 260 brass is sometimes called cartridge brass. This wire has a soft temper and stays in place when bent.

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.

Ultra-Strength Easy-to-Form 510 Bronze Wire

Because 510 bronze is very strong and formable, it is the best choice for applications involving repetitive motion, such as springs and bellows.

Copper

Silver-Plated Multipurpose 110
Copper Bars with Rounded Edges

An ultra-thin layer of silver makes these bars slower to tarnish than unplated copper to provide low electrical resistance at contact points over time.

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.

Mirror-Like Multipurpose 110 Copper Wire

This wire is polished to a mirror-like finish.

Super-Conductive 102 Copper Balls

With 99.99% copper content, 102 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 lug.

High-Temperature Nickel-Clad Copper

This copper wire is clad in nickel to provide excellent corrosion resistance at temperatures up to 1200° F while maintaining high electrical conductivity.
