Classification
Brazing alloys are classified according to AWS A5.8/A5.8M SPECIFICATION FOR FILLER METALS FOR BRAZING AND BRAZE WELDING (2004). Similar to a chemical composition, it comunicates the alloys present.
Silver Brazing Alloys
Safety-Silv A45 - BAg-5 - 45% Silver - Good for small fillets
Safety-Silv A50N - BAg-24 - 50% Silver, 2% Nickel - Similar to 56% but with a higher melting point.
Safety-Silv A56T - BAg-7 - 56% Silver. It is said to be the flowiest of the higher strength silvers. Very low melting point. It is very expensive stuff, about $30 per troy ounce.
- For braze-ons, I am trying this first. 1/16"
Brass Based Alloys
GasFlux C-04® Nickel Bronze - RBCuZn-B
Aufhauser C680 Low Fumeing Nickel Bronze - RBCuZn-B
Fluxes
Fluxes are specified per AWS A5.31 SPECIFICATION FOR FLUXES FOR BRAZING AND BRAZE WELDING
STAY-SILV White Flux - For silver brazing steels.
STAY-SILV Black Flux - For silver brazing stainless steels.
