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.

Polished on one side to a reflective, mirror-like finish.

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.

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.

In addition to being conductive, these 17510 beryllium copper bars are non-sparking and non-magnetic, so they’re used in mines and oil rigs, as well as for navigational tools.

Keep shim stock in a variety of thicknesses on hand with these sets. Cut into custom shapes to fit your application.
