By weight, copper > stainless steel > iron > aluminum > pure titanium. The density of stainless steel material is about the same as that of iron material. The  long screw  under the same specification has no difference in weight. But if it’s very light, it’s basically titanium and aluminum. Stainless steel with iron material  long screw , can distinguish through the magnet, but sometimes stainless steel material screw specification is relatively small, may contain some weak magnetic, will cause the screw will also be magnet to suck.
