Alloy 170

Harris 17 & 170 copper-zinc-nickel brazing alloy is used for braze/welding steel and cast iron. It can also be used for brazing tungsten carbide-to-steel where higher joining temperature is not objectionable. The nickel addition provides hardness and strength compared to the standard bronze alloys. This characteristic makes it ideal for build-up and overlay. Harris 17 & 170 flows easily and deposits can be machined. It can be deposited using oxy-fuel torches. Harris 17 & 170 is available bare or flux coated. Flux-coated rods are pre-coated with a flexible, flux coating for convenience and ease of deposition.
