Nickel-based brazing materials BNi16

Classification：BNi16

Product Features：
BNi-16 is a nickel-based brazing filler metal belonging to high-temperature alloy brazing materials, primarily composed of nickel (Ni) with added elements such as chromium (Cr), boron (B), and silicon (Si). It is designed to achieve excellent high-temperature resistance and welding strength through solid solution strengthening and eutectic reactions.

High-Temperature Strength: BNi-16 maintains high tensile strength and creep resistance at high temperatures (typically up to 900°C or higher), benefiting from the solid solution strengthening of the nickel matrix and the synergistic effect of elements like Cr and B.
Corrosion Resistance: It performs excellently in both oxidizing and reducing media, especially suitable for environments containing halide ions (such as Cl⁻), making it ideal for brazing chemical equipment and nuclear reactor components.
Wettability: By controlling the content of B and Si, BNi-16 can effectively wet the surface of the base metal during brazing, forming a dense joint.

Application Fields：

Aerospace: Used for welding high-temperature components such as turbine blades and combustion chambers due to its stability in high-speed gas flows and high temperatures.
Nuclear Industry: Brazing fuel elements and radiation-resistant structural components of nuclear reactors.
Energy and Petrochemical: Manufacturing high-temperature and high-pressure reactors, heat exchangers, and pipeline systems.
Electronic Devices: Hermetic welding of high-precision radiators or vacuum pipe fittings.

Packaging: Aluminum foil bags, steel drums, plastic barrels, pallets, customized packaging
Shape: Paste, Powder, and Foil

Silicon and chromium synergistically form a dense composite oxide layer (such as Cr₂O₃-SiO₂), enhancing the stability of the joint in high-temperature oxidation or corrosion environments.
