Copper 101
Copper 101 is widely used for Used for electrical and electronic conductors, wave guides, cavity resonators, superconductor matrices, vacuum tube and solid-state devices, and glass-to-metal seals.
Copper 102
Copper 102 is an oxygen-free copper with extremely high electrical conductivity and good form ability. These characteristics make it particularly useful for electrical connectors.

Copper 103
Copper 103 is of high quality and available in different size ranging from minimum of 1.20 mm to maximum of 10.8 mm.
Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion. The best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead.
