phosphor copper welding rod

Phosphorus-Copper Brazing Alloy has features of good-flowing,low price and good workmanship, it needn't use flux.it appropriate for touch-welding,gas flame welding,high-frequency welding and welding inside stove,welding joint has better intensity and electric conductivity.it shoud use flux when weld copper alloys. Brazing Alloy Composition(%) Melting Range (oC) Principal areas of application Cu P Sn Impurities Total Solidus Liquidus SCuP-2 6.8-7.5 - Small 0.15 710 800 Good flow property,economical,widely used in the brazing of presetting in air-conditioners and the no-vibratim load areas.
