    Description

    Copper M2 is used: for the production of high quality semi-finished products and alloys, copper-based pressure treated; for the manufacture of products of cryogenic equipment; round drawn thin-walled tubes; drawn rectangular tubes, intended for the manufacture of waveguides; drawn capillary tubes used in propose hypersound or ultras and instrumentation and refrigeration equipment; cold-rolled foil and strip, cold-rolled and hot-rolled sheets and plates of General purpose; radiator tape, is intended for manufacturing cooling tubes and radiator fins.

    Note

    M2 copper produced by fire refining and smelting waste and scrap of copper.
