BNi-7
Features:
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.
Application:
High-temperature alloys, refractory metals (such as nickel alloys, cobalt alloys, molybdenum, tungsten, hard alloys)
Sintered diamond products
Packing:

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.
