The quick research revealed that you would need to have either Fe, Ni, or Co in the mixture to get yourself a magnetic alloy. Otherwise, they will be not attracted by a magnet. Also, you can check for some information about alloys here http://www.americanspecialmetals.com/hastelloyb-3.html didn't have much time to browse through it and find what I needed, buy maybe you will have more luck. Cheers!
