I believe it's cast from "the finest copper alloy from Italy." Copper, if it's the right alloy, should hold up pretty well. I guess there's something for everyone. Not for me. I like the $3 one I have. It holds the reed down just fine....or practical if the casting is a zinc alloy or brass without hardened steel threaded inserts. Tinkerers will enjoy turning all those screws until the threads are stripped.
