Nickel-based
Nickel-based filler material is a brazing filler composed of nickel as the matrix, supplemented with low-melting-point elements (such as boron, silicon, phosphorus, etc.) and strengthening elements (such as chromium, cobalt, molybdenum, tungsten, iron, etc.)
Nickel-based brazing filler metal is a brazing material composed of nickel as the base matrix, combined with low-melting elements such as boron, silicon, and phosphorus, as well as strengthening elements like chromium, cobalt, molybdenum, tungsten, and iron.
BNi-2 nickel-based brazing filler metal
BNi-2 is one of the most widely used nickel-based brazing alloys, characterized by a low melting temperature and excellent wettability and fluidity. During brazing, the base metal grains do not grow, thereby minimizing the risk of degraded 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.
