Description
Nickel Bronze (also referred to as Manganese Bronze)
is similar to Naval Bronze, however iron, manganese
and nickel have been added to the analysis. The iron
and manganese increases the hardness and strength of
the weld deposit while nickel ensures uniform distribution
of iron in the deposit. Nickel Bronze is primarily used
to braze or oxyacetylene weld steel, cast iron, brass
and bronze. Also used for building-up wearing surfaces
and bearings. Flux required. Use a boric acid or borax
commercial flux. A neutral or slightly oxidizing flame
should be used. Preheating may be required for some
applications.
