Doing some reading up on scandium.
Turns out the "scandium" frame S&W revolvers are really a scandium-aluminum alloy.
That's a whopping 0.1% to 0.5% scandium by weight.
But it really does magical things to the mechanical properties of the alloy!
SCIENCE!

Hey, a major company is arguing you should switch to them because they are only 1% behind their competitor... so hey, a revolver frame that is pure Aluminum instead of 0.5% Scandium should be good enough, right??? :-)
ReplyDeletePure aluminum would be a bad plan.
DeleteJust like using pure iron would be a foolish material for the barrel.
I remember reading when they came out that scandium cost, like, $7000/lb or something and so it was fortunate that only a salting was required to up the tensile strength of the aluminum alloy.
