Where is brass in the materials list?

I’m trying to cut brass, but the materials list in WAM doesn’t list brass under metals. Am I missing something? Should I create a new material? If I create ‘brass’ what settings should I include? Thanks!

Brass doesn’t appear to be in the materials list in WAM.

But the values are given on this page. Materials Specs - WAZER
