WELDING DESCRIPTION
NAME:copper brass rod
BAND:
OTHER NAME:HS221
DETAILED INTRODUCTION:
HZ-S221 is a kind of copper and zinc brazing alloy, and available for gaseous flame brazing, high frequency brazing, furnace brazing, resistance welding etc. HZ-S221 has good welding performance, and it is widely used for brazing of copper and copper alloy, steel, copper nickel alloy, gray cast iron, cemented carbide etc. It could replace H62 filler metal and be used as wire of brazing brass. HZ-S221 is 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, HZ-S221 is often used by surface welding worn parts of metal, such as bearing valve sealing surface, propeller. HZ-S221 brass wire should work together with copper gas welding flux when oxyacetylene gas brazing.
