can use = may use? i.e. it is legal to use
can use = practical to use? i.e. it is dense and strong
can use = theoretically use? i.e. it is really heavy in a small volume
If the last, and you're needing a dense material for increasing weight.. Formula 1 racing teams build super light race cars (well under the minimum weight requirements) and then add a tungsten-nickel-iron alloy (a product called DENSIMET(R)) for ballast. I have no idea how much it costs, but given F1 budgets, it can't be cheap (likely failing the first and second meanings of "can use").
