Copper phosphorus Filler Metals has good fluidity. Mainly used for brazing copper and copper alloys. It is also sometimes used for silver, tungsten and molybdenum, but it cannot be used for welding steel, nickel and nickel alloys.When we put silver into Copper phosphorus Filler Metals , it can reduce the melting point of welding,improves wetting ability, strength and toughness.When we use Copper phosphorus Filler Metals to weld copper and silver, no brazing flux is required, when we weld brazing copper alloys, brazing flux is required.
