Castolin 16 Brass solder

Castolin 16

Nickel-alloyed CuZn-based brazing alloy with added silver. Silver reduces the surface tension of the molten solder and improves the toughness of the solder joints. Very good flow and wetting properties. Good modeling properties. High strength and elongation. Smooth, dense and non-porous seams.

Applications
Preferred for gap brazing, e.g. unalloyed and low-alloy steels (structural steels, case-hardened, tempered and nitriding steels, nickel, nickel alloys, malleable cast iron (GTW), nickel silver (CuNiZn alloys) as well as for joint and build-up brazing of wear-resistant layers on the materials mentioned.
Typical applications are
Motorcycle and bicycle frames, vehicles, tubular steel furniture, protective grilles, gratings, railings, measuring devices, instruments, pipelines, tools.

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; neutral to slightly reducing), HF induction, oven (with and without shielding gas).
