The Nickel-based brazing alloy BrazeLet^® BNi2 provides high strength when brazing stainless steel material in vacuum or protective atmosphere. The brazing alloy is typically used for brazing heat exchangers such as EGR coolers in automotive or tap water applications in home or industry where high corrosion resistance is not required.

BrazeLet BNi2 contains boron as melting point depressants and can therefore be used at relatively low temperatures.
