BNi-2
Features:
1. Superior High-Temperature Performance: Brazing temperature range of 1050-1200°C, joint temperature resistance up to 980°C. Resistant to high-temperature oxidation and heat corrosion, with excellent compatibility with nickel-based/cobalt-based alloys. 2. High Wettability and Fluidity: Containing boron and silicon elements, it lowers the melting point and enhances the wetting and penetration ability to stainless steel and high-temperature alloys. 3. Flexible Forms to Adapt to Processes: Paste: Convenient pre-placement, suitable for brazing complex structures (such as honeycomb seals). Powder: Can be sprayed or pre-coated, suitable for automated production lines. Foil: Uniform thickness (0.05-0.2mm), precision assembly without splashing.
Application:
Aerospace: Jet engine components, combustion chambers, and heat exchangers heavily rely on robust high-temperature joints. BNi-2 brazing performs excellently in these applications.
Automotive: Exhaust manifolds, turbochargers, and other high-heat components benefit from the strength and heat resistance provided by BNi-2 joints.
Medical devices: Components requiring biocompatibility and strength, such as orthopedic implants or dental prosthetics, can be effectively joined using BNi-2 brazing.
Power generation: Gas turbines and other high-temperature power generation equipment rely on reliable joints. BNi-2 brazing can provide the necessary strength and performance.
