About Copper, Brass, and Bronze

Harsh Environment High-Current Distribution Bars

Protect connections against corrosion.These bars are tin-plated copper and have stainless steel terminals.

Modular Distribution Bars

Build your own distribution system by adding terminal blocks to these bars.

Grounding Bars

Mount these bars wherever you need to create a central grounding point.

Grounding Blocks

Connect multiple ground wires in tight spaces such as cabinets and enclosures.

Copper

Multipurpose 110 Copper Bars with Rounded Edges

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.

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.

Multipurpose 110 Copper Sheets and Bars

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.
