Of course. The only known usage of Scandium is as an additive to aluminum alloys. While I'm not sure what concentration S&W uses, I do know that the normal amount of scandium used to strengthen aluminum is usually less than 0.5%.

P.S. If they could find a way to make a frame entirely out of scandium, you could probably expect the retail price to be in the 100's of thousands per unit. It is an exceptionally rare element.
