About Copper, Brass, and Bronze

Multipurpose 110 Copper Rods and Discs

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.

Super-Conductive 101 Copper Rods and Discs

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.

Titanium-Clad Super-Conductive 101 Copper Rods

A thin layer of titanium is bonded to these copper rods for long life and dimensional stability in corrosive environments.

Super-Conductive 101 Copper Tubes

Easy-to-Machine 145 Copper Rods

Also called tellurium copper, 145 copper contains tellurium, which makes it more machinable than all other copper while maintaining good corrosion resistance and high electrical conductivity. It’s often used for transformer and circuit-breaker terminals, welding torch tips, and fasteners.

High-Strength 182 Copper Rods

182 copper is stronger, harder, and more wear resistant than 110 copper. Also known as RWMA Class 2 chromium copper, it's commonly used in resistance welding, for circuit-breaker parts, and for molds to make plastic parts.

High-Strength 182 Copper Hex Bars

Weldable 122 Copper Tubes

The addition of phosphorus makes 122 copper easier to weld and braze than 110 copper. It has excellent resistance to corrosion caused by water, soil, and weather, making it the go-to material for plumbing and underground applications.

Fastening and Joining

Bronze Threaded Rods

Bronze threaded rods are stronger and more resistant to salt water than brass rods.

Spot Welding Electrodes with Flat Tip

The flat tip creates a larger weld and can be used when appearance is less important.

Spot Welding Electrodes with Pointed Tip

The pointed tip is best for tight areas or for a small weld.

Cap-Style Spot Welding Electrodes with Flat Tip

The flat tip creates a larger weld and can be used when appearance is less important.

Cap-Style Spot Welding Electrodes with Pointed Tip

The pointed tip is best for tight areas or for a small weld.

Grounding Rod Clamps

Connect bare-copper ground wire to grounding rods.
