Nickel brazing filler metal
The BrazeLet® BNi family offers BNi-based filler metal powders suitable for different applications, brazing conditions and braze properties. Applications are found in a wide range of automotive as well as industrial areas. Typical automotive applications are EGR-coolers (Exhaust Gas Recirculation) for diesel as well as gasoline engines, catalytic converters and fuel rails. Brazed plate heat exchangers, heaters and boilers are common industrial applications.

BrazeLet BNi2
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.

BrazeLet BNi5
BrazeLet® BNi5 is a Nickel-based brazing alloy with a good wetting behaviour on stainless steel material in vacuum or protective atmosphere brazing.
The high level of alloyed chromium results in a good hot gas and acid corrosion resistance. The high melting range of BrazeLet BNi5 makes it suitable for applications working at very high temperatures, for instance, EGR coolers for trucks and automotive metal catalytic converters.

BrazeLet BNi7
BrazeLet BNi7
BrazeLet® BNi7 is a Nickel-based brazing alloy that provides high strength when brazing stainless steel material in vacuum or protective atmosphere. Typical applications for this brazing alloy are heat exchangers not requiring high cossosion resitance, for instance automotive EGR coolers and domestic or industrial tap water applications.
BrazeLet BNi7 contains phosphorous as melting point depressants and can therefore be used at relatively low temperatures.
