McMaster-Carr lists Alloy 1100 as having the best conductivity. It is
interesting that on the Webb page this alloy is listed as only containing
0.12% Cu but in the catalog it has 0.95%Fe-Se%, 0.05-.2% Cu, and some
other stuff. A 6"x6"x1/8" sample sheet is only $4.24 Part #88685k1. Check
out the web sight.
