HARRIS WELCO 170 is a thin flowing, high strength alloy for maintenance, repair and fabrication applications on steels, copper, copper alloys, nickel and nickel alloys. It is particularly well suited where close-fit, strong "sweat" joints are necessary such as in the brazing of bicycle frames, tubular furniture, etc. HARRIS WELCO 170FC is flux coated.
Features
Tensile strength -- Up to 95,000 psi
Brazing temperature range -- 1720°F to 1800°F
Uses substantially less filler material than a regular brazing rod
Applications
The area to be brazed should be clean. No preparation other than cleaning is required if the thickness is 1/8" or less. A butt joint only is needed. Heavier sections should be beveled approximately 15° on each side of the two pieces to be brazed. Use a neutral flame with WELCO 17 FLUX. Flux residue should be removed by wire brushing with hot water.
