Stainless tends to crack under repeated hammering. Inconel is great for beating on, under high temperatures.
a small manufacturer of custom 1911 style pistols that used beryllium/copper alloy for the frame. This would have been 20-25 years ago. Very unusual looking pistols
I hope you're not talking about S&W "Scandium" frames... they are a total scam. They use an aluminum alloy which is approximately 0.15% scandium.I completely forgot about the lightweight "exotic" metals like scandium, thanks nicholst55!

Yes, that's part of why it's a scam. Alloys are named for the primary metal - their frames are ~90% aluminum. It is aluminum alloy with a very small proportion of Scandium which does not significantly alter its properties. Here's the info from S&W's patent:Doesn't S&W usually refer to it as "Scandium Alloy"?
The alloy is composed of 0.05 % to 0.15 % scandium, 7.5 % to 8.3 % zinc, 1.6 % to 2.2 % magnesium, 1.6 % to 2.0 % copper, 0.02 % to 0.04 % chromium, 0.05 % to 0.15 % zirconium, and 87 to 90 % aluminum.
Isn't the Glock 7 all ceramic?
Conqueror said:They could have called it "Zinc alloy frames" but that probably wouldn't have sold as well to so many gullible individuals. While this alloy is stronger than some regular aluminum alloys, it is not stronger than all of them. Plain old 7068 aluminum is stronger, for example.
