Industrial Grade BNi?2 PowderBulk Supply Rite Material

4. Good corrosion resistance: Chromium addition providessatisfactory resistance to oxidation and moderate corrosiveenvironments. Note: Boron may diffuse into thin-walled substratesand form brittle intermetallic phases if process parameters are notwell controlled.
5. Flexible product forms: Gas-atomized BNi-2 powder features highsphericity and good flowability, easy for making brazing paste;amorphous BNi-2 foil delivers consistent thickness for precisionassembly.
Main Applications
Aerospace & Aviation
BNi-2 is a standard vacuum brazing filler for aerospace components.It is used to join stainless steel and superalloy parts foraircraft turbine cold-section assemblies, aerospace heatexchangers, honeycomb structures, engine manifolds and valvecomponents, serving under combined high temperature, thermalcycling and mechanical load.
3. High-temperature joint strength
After brazing — especially with a diffusion hold — BNi-2 jointsshow:
high room-temperature strength
retained strength at elevated temperature
good creep resistance
remelt temperature higher than the original liquidus afterboron/silicon diffusionRite Material
Common sizes: -200 mesh, -300 mesh, -325 mesh, or customizedmicrons
5. Typical Applications
Aerospace:? jet engine structural members, turbine components,compressor vanes, stators, honeycomb structures, seals
Energy & turbines:? gas turbine parts, heat exchangers, EGRcoolers, nuclear e outside the core
Stainless steel & superalloy joining:? austenitic/martensiticstainless steel, Inconel, Hastelloy, cobalt alloys
Cutting tools & wear parts:? brazing diamond segments, tungstencarbide inserts, cemented carbide tools
Automotive & e-mobility:? turbocharger parts, stainlesscooling-system components, li plates, heat-exchangerassemblies
 
Industrial e:? chemical-processing hardware, food-handlinge, valves, honeycomb panels
6. Process Notes
Best brazed in vacuum, pure argon, or very dry hydrogen?
Fast heating helps oid liquation
A diffusion hold improves ductility and raises servicetemperature
Not recommended for nuclear core? applications because of boroncontent
Thin sections and less-ductile base metals require smallclearances, minimal filler, and controlled cycles
