Available bare of flux coated. Harris Alloy 170 is a copper/zinc/nickel alloy developed 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 170 flows easily and deposits can be machined. Harris 170 can be deposited using oxy-fuel torches. Flux coated rods are pre-coated with a flexible, flux coating for convenience and deposition ease.
