About Copper, Brass & Bronze

Compare over 30 copper, brass, and bronze alloys to find the right material for you—all with material certificates for traceability.

Copper Wire

Highly conductive and soft enough to form, copper wire is the go-to for electrical jobs. It's often used to power motors, create grounding, and wire control panels, lights, and transformers.

Tin-Coated 110 Copper—More corrosion resistant and easier to solder than uncoated 110 copper wire.

Mid-Cable Support Grips

When the end of a cable is not accessible, wrap the mesh on these grips anywhere along the length of the cable to provide support. Lace the mesh closed with the included lacing wire. Also known as bus drop grips, these grips support cable weight and relieve tension. They also damp vibration in hanging runs of cable, rod, and tubing.
