Turns out you can! But it's $750 for a one-centimeter cube, because the US government limits commercial sales of DU to 15kg per year.

I thought they used DU as counterweight in some civilian airliners? But maybe the manufacturers have some special license to procure more DU..?

Depleted uranium has indeed been used in airplanes. Some models of 747 have a ton or so of depleted uranium, though I believe this practice was phased out in later models.

It's not just planes though. Some sailboats have been made with DU keels. Usually lead is used, but DU would presumably allow for a smaller (thinner?) keel.

You can dig it up in Iraq.
