WWW PHOS-C-WELD

WWW PHOS-C-WELD (ER CuSn-C) 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.
