Chemical designation | NiCr20Co18Ti |
Etching | Kalling 2 |
Material 2.4632 is a nickel based alloy with chromium and cobalt, alloyed with titanium and aluminium. This material is characterised by a high creep rupture strength at temperatures up to approx. 920°C.
It was etched with Kalling 2. After 10 minutes of etching, holes had already appeared in the interdendritic area and the matrix was unfortunately not further strengthened.
