Bluewater Thermal Solution’s nickel brazing process typically treats stainless steel and carbon steel assemblies with low temperature nickel brazing filler materials. Depending on the desired properties of the parts, assemblies and filler materials are placed in our furnaces or heating stations and the brazing filler materials are then diffused into the joints via capillary means. Most nickel alloys used in Bluewater’s nickel brazing method are chosen for their corrosion resistant and superior temperature resilient properties. For some, this becomes a problem in nickel brazing scenarios because the base material must always have a higher melting temperature than the brazing filler material, and pure nickel has a melting point of 2651°F(1455°C). Fortunately, Bluewater technicians have the right processes and procedures in place to help work around these conflicting characteristics. We alloy elements like boron with a nickel filler material to lower the melting point and can then utilize the appropriate nickel base filler material to apply it as slurry, preform or powder. Certain alloys also require nickel plating before the process begins and Bluewater can help accomplish this. No matter what circumstances arise, our technicians can help select the appropriate alloyed nickel filler material based on our clients’ needs. Utmost care and proper diffusion of the nickel brazing alloy is ensured.
