Phos-Copper Brazing Alloys phos-Copper brazing alloys are easy-flow, low cost ones and shows perfect performance in contact brazing, oxy-acetylene brazing, induction brazing and furnace brazing. The joint strength is higher and the conductivity is better. A flux is required while brazing brass to brass.
