  • Environement Friendly Copper Zinc Brazing Welding Alloy Rod Rbcuzn A Filler - China

    price: contact company for price

    We are professionally managed company engaged in the fabrication and

    supplying a wide range of brass welding alloy. These are made from from

    pure metals of precise chemical specifications as per the varied quality

    standards. Our collection delivers consistent performance due to its

    excellent brazing properties. Our range adheres to SGS standards. These

    are high demands by our clients belonging to various industries.

    HS221 brass rod is a kind of Cu-Zn brazing alloy, and available for gaseous flame brazing, high-frequency brazing, furnace brazing, resistance welding etc. HS221 has good welding performance, and it is widely used for brazing of copper and copper alloy, steel, copper nickel alloy, grey cast iron, cemented carbide etc. It could replace H62 filler metal and be used as wire of brazing brass. HS221 is a special brass brazing wire 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, HS221 is often used by surface welding worn parts of metal, such as bearing valve sealing surface, propeller. HS221 brass wire should work together with copper gas welding flux when oxyacetylene gas brazing.

    Item Number:HS221, RBCuZn-A(AWS)

    Chemical Composition (%):Cu 59-61, Zn Remain, Sn 0.8-1.2, Si 0.15-0.35

    Melting Point:890-905°C

    Recommended Temp.:910-945°C

    Advantages and Usage:For brazing copper and copper alloy, steel and cast iron in the method of flame brazing, furnace brazing and induction welding

    Caution:1.The surface of oil and oxide on the work pieces should be cleansed carefully before brazing .

    2. Preheat the work piece to 400 to 500°Cbefore brazing.

    3. Matching flux should be used together when brazing.

    4.Neutral flame or slight oxidizing flame could be used when flame welding. Appropriate decrease welding temperature, increase welding speed, reduce residence time of molten pool in high temperature to lessen the evaporation and oxidation of zinc.

    We could make it in ring, wire, sheet, rod sharp to meet your requirement.

    You are welcome to visit our factory and inspect the quality of the brazing materials.

    Pls contact us if any problems relate to our product.
