    Description

    Copper M2r is used: for the production of high quality semi-finished products and alloys, copper-based pressure treated; cold-rolled foil and strip, cold-rolled and hot-rolled sheets and plates of General purpose; drawn and cold-rolled pipes used in heat exchangers; drawn capillary tubes used in propose hypersound or ultras and instrumentation and refrigeration equipment; round welding wire and welding rods round drawn and extruded with a diameter of from 1.2 to 8.0 mm, designed for gas welding of General purpose constructions of copper.

    Note

    Copper M2r obtained by melting of cathodes and scrap copper deoxidation with phosphorus.
