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.

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 and 102 copper have higher purity than 110 copper, resulting in superior electrical conductivity. They're commonly called OFE and OFHC copper. Use them in electrical applications, such as for coaxial cables and terminal lugs.
