PHOSPHOR BRONZE

WWW PHOS-A-WELD (ER CuSn-A) filler metal is a copper-tin alloy containing about 5% tin. It is used to weld bronze, brass and copper. Phosphor Bronze A is frequently used to repair castings and join copper-tin alloys of similar chemical composition.

WWW PHOS-C-WELD contains 8% tin. It is similar in composition tto AWS 5.6 ECuSn-C except that it is offered here as a bare wire filler metal. It is harder and stronger than AWS 5.7 ER CuSn-A, and is preferred for welding phosphor bronzes, high strength bronzes and brasses. The alloy's color matches phosphor bronze well.

WWW Phos C Weld is used with gas tungsten arc (GTAW) and gas metal arc (GMAW) welding processes.
