3/16" X 36" RBCuZn-D Harris™ Alloy 170 Flux Coated 10 lb Box With White

Item Details

Harris� 170FC 3/16" X 36" is a copper/zinc/nickel alloy designed 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 addition of nickel to this alloy provides hardness and strength compared to standard bronze alloys. This characteristic makes it ideal for build-up and overlay. This alloy flows easily and deposits can be machined. It can be deposited using oxy-fuel torches. Applications include maintenance, repair and fabrication on steel, copper, copper alloys, nickel and nickel alloys. Ideal for close-fit, strong "sweat" joints, bicycle frames and tubular furniture. This rod is pre-coated with a flexible white flux coating for convenience and ease of deposition.

Features

• The process is similar to brazing as the base metal is not melted
• Unlike brazing the rod must be continually applied as you move down the joint
• Focus the flame on the part and heat until a dull red appears, then apply the rod, melting the rod with the flame to deposit a uniform braze layer along joint
• Clean the area to be brazed
• Apply with a "braze welding" technique
• Bevel heavier sections approximately 15 degrees
• Use a neutral flame preheat and preheat joint
• Remove flux residue by wire brushing with hot water
• Melting point -- 1750°F
• Tensile strength -- Up to 95,000 psi
• Working temperature range -- 1700°F to 1800°F
• Brinell hardness -- 90-100
• Uses substantially less filler material than a regular brazing rod

Applications

• Overlays and build-up of gear teeth shafts, bearings, valve seats, pistons and other surfaces subject to wear.
• Joining both ferrous and non-ferrous metals

Specifications

• AWS A5.8

Caution

• Keep your head out of the fumes
• Use enough ventilation, exhaust at the flame, or both, to keep fumes and gases from your breathing zone and the general area
• Wear correct eye, ear, and body protection
• Do not touch live electrical parts
