The purity of High Purity Copper produced by our company is divided into three grades: the first grade purity is above 99.995%, the second grade purity is above 99.999%, and the third grade purity is above 99.9999%. Starshining can provide products in the form of rods, plates etc. and customized products according to customer drawings.

High Purity Copper has good electrical conductivity, ductility, low softening temperature, high thermal conductivity at very low temperatures, can be drawn into very fine (10um) copper wire, or can be rolled into very thin (6um) copper foil.
