Copper Cathode 99,97-99,99%

Copper cathode 99.97-99.99% has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed. It contains less impurities that reduce electrical conductivity and thermal conductivity, and a small amount of oxygen has little effect on electrical conductivity, thermal conductivity and processing properties. Cathode copper is widely used in electric power, light industry, engineering, construction, national defense industry and other fields. It is used for winding resistance of various cables, wires, motors, transformers, switches, printed circuit boards.
