    Description

    Copper M3r is used: for the production of copper alloys and other cast alloys; cold-rolled foil and strip, cold-rolled and hot-rolled sheets and plates of General purpose.

    Note

    Copper M3r is produced by re-melting of cathodes and scrap copper deoxidation with phosphorus.
