SilverAlloy A-50


INTRODUCTION

Aufhauser SilverAlloy A-50 may be used on copper, brass, nickel-silver, bronze, steel, and practically all non-ferrous alloys melting above 1450°F (788°C). On heavily galvanized or tinned steel its low zinc content permits absorption of more zinc or tin without embrittling the joint.

Common uses is in brazing electrical applications and in joining dissimilar metals. SilverAlloy A-50 is widely used for brazing in the electrical industry, as well as in the dairy and food industries where the use of cadmium-containing filler metals is prohibited. It also has a broad melting range, making it an ideal choice for filling wide joint clearances or forming large fillets. For best results, use with Aufhauser SilverFlux.

APPLICATIONS

SilverAlloy A-50 is an intermediate temperature silver brazing filler metal with a fairly long melting range. The long melting range is helpful when wide gap joints are brazed and is useful in producing large joint fillets to reduce the notch effect on stressed assemblies. This alloy exhibits high degrees of ductility and malleability, which is an advantage when parts are cold-worked after brazing.
