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.

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.
