Copper Flux Cored Wire

    DESCRIPTION:

    This copper cored wire is a kind of copper and zinc brazing alloy, and available for gaseous flame brazing, high frequency brazing, furnace brazing, resistance welding etc.It has good welding performance.It's a special brass brazing filler metal that contains tin and silicon.While tin improves fluidity, silicon controls evaporation of zinc, and eliminates gas hole to get an excellent welding process. Because of good corrosive and toughness.

    APPLICATION:

    Widely used for brazing of copper and copper alloy, steel, copper nickel alloy, gray cast iron, cemented carbide etc.It's often used by surface welding worn parts of metal, such as bearing valve sealing surface, propeller.
