BrazeLet^® Ni613

The nickel-based brazing alloy BrazeLet Ni613, features a best in class wetting behaviour on stainless steel material in vacuum or protective atmosphere (dry hydrogen or argon). Its high level of alloyed chromium results in a superior hot gas and acid corrosion resistance. The brazing alloy is best suited for brazing heat exchangers such as exhaust gas recirculation (EGR) coolers in automotive or drinking water applications. Compared to most of the standard nickel-based brazing alloys, BrazeLet Ni613 is able to fill larger gaps without brittle phase lines or cracks. The resulting micro hardness in the brazed joint microstructure is less than half when compared to BrazeLet BNi5. This leads to a more reliable and safe brazing as well as more flexibility in part tolerances.
