Too light to be lead. High pitch ring when struck with lead ingot. Has to be better than 20-30 yrs old. Was in the back of gramps garage. I am thinking zinc? Maybe sacrificial anode? We do not live near salt water however.

If you have an accurate measuring device or two, put a known amount of water in a graduated container, then add the piece and see what its displacement is. Once you have its volume, weigh it. If you are lucky and its pure/not an alloy, then its a matter of looking up weights per unit volume.
Zinc is .257#/in3
Lead is .409
Tin is .263
Aluminum is .092

Send me a small piece and I will take it into work and have it annualized.
My bet is it's a hammer die alloy. Zamak or similar.

Unobtainium, yet somehow you got some.
Unobtainium Now that is very rare and rather funny.
I bet Grandpa worked at area 51 and that right there boys and girls is real UFO alloy know as UM unidentified metal so put me down for Freefify oh any odds on this bet.
Reloading to save money I am sure the saving is going to start soon
Well. I pointed a propane torch at an edge for about 20 min. Nothing melted off. Wore my very used disc down before I could get a piece off to try to melt alone. The quest continues. Hha

what kind of propane torch? a soldering torch is not hit enough. try a weed burning torch.
I switched to MAPP gas for my "propane torch" needs. Much faster for household soldering and brazing.
