High Silver brazing alloys can provide perfect performance with low melting point, extensive flow properties and crate strong, ductile ,rust-resistant joints of excellent conductivity ,Suitable for joining all non-ferrous metals and ferrous metal Except Aluminum and magnesium, Flux is needed for brazing except for in protective atmosphere or vacuum brazing .The addition of zinc/Tin can help as temperature depressant and reduce cost of filler metal. Nickel can improve the heat-resisting, rust-resisting and wetting properties of the alloy.
1.good processing property
2. low melting point good wetting ability,gap filling ability and plasticity
3. good electrical conductivity
