Phos-copper ,Phos-Copper-Silver ,Silver-Copper-Zinc,Silver-Copper-Zinc-Tin,Silver-Copper-Zinc-Cd,Copper-Zinc,Aluminum base brazing alloys
| 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. | ||||||||
