Phos-Copper Brazing alloys | ||||||||
DESCRIPTION:Phos-Copper brazing alloys's main materials are copper and phosphorus,it has the characters of easily-flowing, low cost, and perfect welding effect.Needn't to use flux when brazing copper and silver objects, the joints have good strength. | ||||||||
