Nope. I have a .357 and .45 Smith & Wesson revolver made out of it...
Oh, That's Aluminum/Scandium Alloy... Al-Sc is used for firearms... the Aluminum renders the Sc radioactively inert and the combination in alloy hardens things up... Straight Scandium is as flammable as magnesium and quite soft on it's own, even though it's higher up the periodic table than Titanium... and it only takes a few grams of Scandium in Al-Sc to get the desired effect. The most recent trade price I've seen on pure Scandium was a couple years ago... at $10,000 per pound! It is most certainly higher now considering they mine very very little of the stuff annually... I believe the numbers are less than 500 Kg per year. Rare and EXPENSIVE stuff!
