Use of scandium-aluminium alloy frames
S&W is the only firearms manufacturer in the US who is in possession of a substantial amount of scandium for use in their aluminum frames. This metal is extremely rare (only about 4000lbs produced annually worldwide) and considerably strengthens conventional aluminum.
I have a model 6904 auto pistol made in 1993. Is the frame made from scandium alloy? Does S&W use scandium in all models with aluminum frames and since when?
Thanks a lot!

I think all the scandium alloy frames have a special logo that looks vaguely like a drawing of an atom. I have never heard or seen of a semi-auto with a scandium frame. Maybe a PC 1911 if anything.

The 4040 PD was the first Scandium/Aluminum alloy frame Semi-Auto produced by S&W in 2003, the 1911SC came in 2004.
The grips are interchangeable with the 3913NL and the 3913 "Lady Smith"

I can state with certainty that your 6904 does not have a scandium frame. Scandium is mixed in tiny amount with aluminum to make a very strong alloy. A very common use of scandium is in bike frames, which makes it the middle ground price wise before titanium and carbon fiber frames (for bikes).

THANKS ! The reason I asked is because I have been told that conventional aluminum frames are not all that durable. A friend of mine showed me his older Beretta 8000 through which he put close to 10k rounds and if you pressed down on the barrel through the ejection port it moved a bit (first time I ever saw that). He said that was due to wear on the frame and is very common with aluminum frames.
So I thought perhaps my smith is made with scandium. But I guess not. But then again I am just a bit over about 1000 rds and a ways to go yet.

4040PD
Hi BM1,
That's a beautiful gun.
I've got a low mileage 4040PD, myself, but the bluing is showing some holster wear and the white engraving is dulled. Do you have any recommendations on how to spiff it up? I hesitate just to have it reblued since it, likely, would be right back where it is now after some use. Could anyone other than S&W refinish the engraving?
Thanks!
