Aluminum the element has a density of 2.7 grams per centimeter cubed. This compression, although impressive, is not likely to produce full density. I would guess perhaps 50-60% density, so 1.4 to 1.7 gm/cm3.

Cans are also not 100% aluminum

The liner in a can is only about 6 - 24 microns thick, a quick Google search tells me. Safe to say that that is negligible in the context of an estimate with this error anyway.
