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.

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.

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.

Use this tape to modify printed circuit boards, shield components, and prototype wiring-board layout and design.

Made of polyester fabric with a copper/nickel filler, this tape is highly conductive throughout, including the adhesive.

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