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.

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.
BNi-7 brazing filler metal is a nickel-based eutectic brazing alloy with excellent fluidity, capable of flowing into tightly contacted joints. The filler metal has minimal corrosive effect on the base material and is mainly used for brazing thin stainless steel parts. Since it does not contain boron, it is especially suitable for the nuclear field.
