BrazeLet® Ni623

Nickel-based brazing alloy

Höganäs’ unique and patented nickel-based brazing alloy BrazeLet Ni623 is a high temperature brazing alloy suitable to use where both base material and the brazed joints require superior corrosion resistance. The alloy is developed and particularly suitable for brazing high-alloyed austenitic and super-austenitic stainless steels which require special heat treatments and rapid cooling from temperatures around 1100 °C to avoid precipitation of deleterious intermetallic phases.
