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)
