BrazeLet^® BNi3

The nickel-based brazing alloy BrazeLet BNi3 provides high strength joints when brazing in vacuum or protective atmospheres (hydrogen or argon). As it is Cr-free it is less sensitive to marginal furnace atmospheres. The brazing alloy is typically used for brazing nickel-based superalloys and stainless steel components where high elevated temperature strength is important, such as turbine vanes or honeycomb seals. The alloy also has good oxidation resistance. Joint properties can be further improved by employing a diffusion hold after brazing.
