Reliable Vacuum Braze BNi?2Powder Rite Material

Boron and silicon can form hard borides/silicides in the joint.
Avoid excessive soak time
For critical parts, add a diffusion heat treatment
This improves ductility and high-temperature service life
7. Material compatibility
BNi-2 is excellent for:
Stainless steel 304 / 316 / 321 / 410
Inconel, Hastelloy, other Ni-base alloys
Cobalt alloys, cemented carbide, diamond tools
High joint strength at room and elevated temperature
Industry standard for a reason — it covers 80% of high-temp brazingneeds
Best for:? Stainless steel assemblies, heat exchangers, turbinecomponents, diamond/CBN tool brazing, chemical e, generalindustrial brazing
Watch out:? Chromium forms stable oxides → requires good vacuum ordry protective atmosphere; not for nuclear core applicationsRiteMaterial
Its “special” points are not just the chemistry — they are thecombination? of low melting range, excellent flow, and serviceperformance close to stainless steel / superalloys.
1. Narrow melting range, lower brazing temperature
Solidus: 971 °C
Liquidus: 999 °C
Typical brazing temperature: 1010–1175 °C
Because the melting range is only about 30 °C, BNi-2 flowspredictably and fills capillary gaps without overheating the basemetal. It brazes below the solution-treatment temperature of manystainless steels and nickel alloys, so the parent metal does notsuffer grain growth, softening, or distortion.
 
Power & Energy Industry
It brazes gas turbine parts, recuperators, heat exchanger platesand high-temperature valves for power generation e,resisting high-temperature oxidation and thermal fatigue.
