Product Overview
High purity copper is a reddish-purple metal known for its excellent ductility, high thermal and electrical conductivity. It has a melting point of 1083.4±0.2°C, a boiling point of 2567°C, and a density of 8.92g/cm³. It is stable in dry air, but in a humid environment, it may develop copper patina, a protective corrosion layer that prevents further oxidation. High purity copper is available in various purity levels (99.999%, 99.995%, 99.9999%) and can be supplied in different forms such as granules, wire, crucibles, targets, bars, and ingots, depending on customer requirements.
