Characteristics of red copper

High purity, fine tissue, very low oxygen content. No porosity, trachoma, loose, excellent electrical conductivity, high precision of electroetched die surface, after heat treatment process, no direction of the electrode, suitable for precision machining, with good thermal conductivity, machinability, ductility, corrosion resistance and so on. Copper is a relatively pure copper, generally can be approximately considered to be pure copper, electrical conductivity, plasticity are better, but the strength, hardness is worse. Red copper has excellent thermal conductivity, ductility and corrosion resistance. Trace impurities in red copper have serious influence on the conductivity and thermal conductivity of copper. Among them, titanium, phosphorus, iron and silicon significantly reduce the electrical conductivity, while cadmium and zinc have little effect. The solid solubility of sulfur, selenium and tellurium in copper is very small, and they can form brittle compounds with copper, which have little effect on electrical conductivity, but can reduce machining plasticity.
