Copper and silver/copper/phosphorous alloys

Available as

  • rods
  • wires
  • preforms
  • powders
  • pastes

These alloys are manufactured to recongnised international standards. They are suitable for thre fluxless brazing of copper in air, and the brazing of copper based alloys using a seperate flux. The addition of silver helps reduce the melting point of the alloy and increase the ductility and strength of the joint produced.
