Harris® 170 Bare Nickel-Silver Brazing Alloy

Harris® 170 is a copper-zinc-nickel TIG (GTAW) 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 overlays and build-up of gear teeth, shafts, bearings, valve seats, pistons and other surfaces subject to wear. Also, used for joining ferrous and non-ferrous metals. Harris® 170 flows easily and deposits can be machined. Harris® 170 can be deposited using oxy-fuel torches. Conforms to AWS A5.8.
