Hindalco's copper cathodes are branded as Birla Copper and Birla Copper II. Known for its high purity and consistent quality, Birla Copper cathodes are square-shaped plates of 6mm thickness, with 99.99 per cent copper purity levels which are produced using the Mount ISA electro-refining process.
Birla Copper cathodes meet International Quality Standards such as BS 6017 1981 (1989) and u-Cath-1 / ASTM B-115 (1999) and are registered as A-Grade cathode on London Metal Exchange (LME). Birla Copper cathodes are high-grade, and have the lowest levels of various group and individual impurities.
Birla Copper cathodes are used in the manufacturing of continuous cast copper rods which are further used for the wire, cable and transformer industries. They are also used for the manufacturing of copper tubes for consumer durable goods and other applications in the form of alloys and sheets.
