Nickel-alloyed brazing alloy based on CuZn. Good modeling properties. Excellent wetting properties. High hardness and wear resistance. Low coefficient of friction with metallic sliding friction. Can be machined. Technical data Brazing alloy ISO 17672: Cu 773 EN 1044: CU 305 DIN 8513: L-CuNi10Zn42 Flux content* EN 1045: FH 21 DIN 8513: F-SH2 Melting interval (Sol./Liq.) [°C]: 890 - 915 Working temperature [°C]: 915 Density [g/cm3]: 8.3 Hardness [HB]: 160 - 200 * if flux-coated/containing flux Applications For build-up soldering, e.g: Unalloyed and low-alloy steels (structural steels, case-hardening, heat-treatable and nitriding steels), copper and copper alloys, malleable cast iron (GTW), nickel silver (CuNiZn alloys) and cast iron materials (GJS). Typical application examples are Pump impellers, axles, bearing shells, slideways, slide and valve seats, bearing blocks, slide rollers, worm gears, fan and pump shafts, shift forks, control disks and crank pins. Processing instructions Clean soldering areas. Round off edges. Coat soldering surfaces with flux. Heat the tip of the soldering rod and dip it into the flux. Preheat the workpiece widely and continuously. Do not overheat. Remove corrosive flux residues. Heat sources: Flame soldering (acetylene; slightly oxidizing) Delivery form Castolin 185: bare solder rod Castolin 185 XFC: flexible flux-coated solder rod
