About Copper, Brass, and Bronze

Electronics Rack Grounding Bars

These grounding bars fit standard 19” wide electronics racks.

Grounding Blocks

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

Grounding Bars

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

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.

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.

Highly Conductive 6101 Aluminum

6101 aluminum is chiefly used as a lightweight and economical alternative to copper in electrical applications, such as bus bars in switchboards and battery banks.
