Product Specifications


AM Ni-3 is a Nickel based brazing alloy primarily used to join stainless steel, nickel and cobalt  based alloys. AM Ni-3 is excellent for corrosion and oxidation resistance in high temperature  applications. 


Brazing Characteristics 

AM Ni-3 brazes very well in hydrogen and vacuum atmospheres. AM Ni-3 is a free-flowing alloy  (within the capillary) and will diffuse into the base metal creating an inter-metallic layer.  Recommended joint clearance at brazing temperature for AM Ni-3 is 0.000 in. – 0.002 in. (0.00  mm – 0.05 mm). A minimum brazing temperature of 1930°F (1055°C) is recommend for furnace  and vacuum applications 



AM Ni-3 conforms to American Welding Society (AWS) A5.8/A5.8M 2019: Ni-3 and Society of  Automotive Engineers (SAE) AMS 4778
