I'm sure someone will chime in with a variety of lists and scales that've been made over time. But to answer the part about pulltabs and gold rings, just be forewarned that there are a million different kind, shape, sizes, carots, etc... of gold rings, and a million different variations of tabs, foil wads, beaver tails, can slaw, etc.... Even the tabs in your selected hunt site are fairly uniform (all from the same brand, size, thickness, etc...), then you can hone in on a certain TID cursor-spot to ignore. But I gaurantee you that the minute you start ignoring a certain TID spot, there will be some type gold jewelry or rings that might also fall into that same TID spot. And the minute you start trying to pass a commonly recurring type of tab wherever you are, you will find that bent-over ones, chopped ones, ones-on-edge, etc... will not peg exactly as a nice flat shallow one will.
So for now, no machine can conclusively tell aluminum from gold. If you are in a place where the aluminum ratios are just too punishing, try going to swimming beaches (especially on eroding ocean beaches after swells/tides) where all the light stuff has been removed by mother nature

Even if you're in an in-land state, lake swimming beaches will have higher ratios of jewelry, than turf.
