2.4632 | NiCr20Co18Ti

Numeric designation2.4632 | AISI Alloy 90 | UNS N07090
Chemical designationNiCr20Co18Ti
EtchingKalling 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.
