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.

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.
