BNi-2
Features:
BNi-2 is one of the most widely used nickel-based brazing alloys, characterized by a low melting temperature, good wettability, and fluidity. During the brazing process, the base material grains do not grow, which helps prevent deterioration of component performance.
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.

Application areas
Brazing
ZnAl5 (melting point 382℃) is a zinc-based eutectic filler metal suitable for brazing pure zinc and zinc alloys. ZnAl15 (425-460℃ solid-liquid phase) is used as a universal brazing filler metal for aluminum-aluminum brazing and aluminum-copper brazing with excellent spreading and mechanical properties

The carbon and boron in BNi-1 brazing filler metal can diffuse into the base material during the brazing process, thereby increasing the remelting temperature of the brazed joint. This filler metal has a high chromium content, so the brazed joint exhibits good high-temperature performance and is suitable for components subjected to high stress at elevated temperatures.

BNi-5 brazing filler metal does not contain boron, significantly reducing its effect compared to the base material. It is suitable for brazing thin parts. This filler metal has a high melting temperature and brazing temperature. Due to its high chromium content, the joint's high-temperature strength and oxidation resistance are comparable to BNi-1.
