Aufhauser SilverAlloy A-50Ni2 is a cadmium-free silver brazing alloy. Addition of nickel to the silver-copper zinc alloy imparts corrosion properties which retards joint or interface corrosion of the brazed assembly.

APPLICATIONS

SilverAlloy A-50Ni2 is a suitable replacement for the cadmium-containing BAg-3 alloy. Its low liquidus of 1305°F (707°C) reduces surface oxidation and sensitization to stainless steels. Typical applications are the joining of 300-series stainless steels in the food, medical, and dental fields. The nickel element in SilverAlloy A-50Ni2 also improves the bond strength when joining tungsten carbide cutting tips. SilverAlloy A-50Ni2 is used for joining most ferrous and non-ferrous metals except aluminum and magnesium. Good replacement for SilverAlloy 50N in carbide brazing.

GENERAL INFORMATION

ADDITIONAL INFORMATION

Addition of nickel to the silver-copper zinc alloy imparts corrosion properties which retards joint or interface corrosion of the brazed assembly. The nickel element in SilverAlloy A-50Ni2 also improves bond strength when joining tungsten carbide cutting tips. SilverAlloy A-50Ni2 is a suitable replacement to the cadmium-containing SilverAlloy Cd-50Ni3 alloy. Its low liquidus of 1305°F reduces surface oxidation and sensitization to stainless steels.

Generally, the joint strength using SilverAlloy A-50Ni2 will surpass the strengths of the base metals. Strength is a function of the base metals being joined, type of joint, design of joint, joint clearances and brazing procedures. The recommended maximum operating temperature for SilverAlloy A-50Ni2 is up to 700°F (370°C).
