It's way too cost prohibitive for FIRST use. I don't know where you can buy it in it's raw form.
it's original use was on USSR ICBM's on submarines under the polar ice caps. The missiles would have their fins ripped off, so they started making them out of an alloy of scandium and aluminum, giving them the strength to punch through the ice.
