These sheets and bars come with a traceable lot number and test report.

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.

One side of these sheets has a brushed finish with grain lines running in one direction to mask fingerprints.

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.

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.

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.

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.

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.
