Hi PF,
As you all may know, the densest naturally occurring material is Osmium, which is 22.59 g/cm3...but it also costs $100/g. Is there any manmade dense material that is 25 g/cm3 and under$1/g? I know lead is the "dense" material to buy in bulk, but even that is only 11 g/cm3.

Any help would be great :D

I don't think so.

Tungsten is 19.6g/cm3 and only a few cents per gram raw. Finished parts can vary but under a dollar per gram is possible. It is rather difficult to work with due to its hardness.

What size and shape do you need?
