BrazeLet BNi7

Nickel-based brazing alloy that provides high strength when brazing stainless steel material in vacuum or protective atmosphere.

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.
