I'm not sure how to buy it, but the Department of Energy has about 500,000 metric tons of depleted uranium. Much is in the form of UF6 gas cylinders, rather than the metal. When alloyed with a bit of titanium, the machining properties are similar to steel, except that the chips are pyrophoric, and you don't want to touch or inhale the dust. Tungsten is about the same density (~19 gm/cm3), and more readily available. It is also a pain in the ass to machine, since it is brittle and very abrasive. Use carbide tools and setup similar to aluminum. I haven't checked prices in a long time, but tungsten is something like $20-40 per pound. - bob mackey flying a 235 building a 320 103MD -at- pure-flight.com [use this email address - the one at the top is spam bait]
