How to assign Alloy as a material in CST?

Hello,

I am using a material nitinol for my simulation which is 55% Nickel and 45% Titanium. Does any one knows how to assign this material in CST?

For which analysis? It's non-magnetic, probably only conductivity matters.

Nickel is magnetic at low frequency. However, I am not sure whether the alloy is magnetic or not. I have never used memory metal before. But I can research on that. Thank you for your response.
