Copper 101

Copper 101, or oxygen-free copper, is the name to an extremely pure metal that comes in at about 99.99% Cu. This high purity level gives it exceptional conductivity, so it is often referred to as HC (high conductivity) copper. It also serves as the base material for brass and bronze alloys. Its high conductivity makes it ideal for busbars, waveguides, and coaxial cables.

Copper C110

Copper C110, or Electrolytic Tough Pitch (ETP) Copper, is another highly pure option. It is not as pure as copper 101, however, instead weighing in at 99.90% Cu. It is the most widely used copper alloy because it is more cost-effective and suitable for most electrical applications. This grade is also easier to machine than copper 101.

Copper 932

Copper 932 is also known as bearing bronze. This alloy has excellent anti-friction properties, making it ideal for bearings, bushings, wear strips, and other light-duty applications.
