Alloying Aluminum Alloys with Scandium | Metal Science …
Scandium is one of the most effective alloying components of aluminum alloys. A small addition of scandium (about 0.2 – 0.3%) facilitates an increase in strength properties of wrought semiproducts of aluminum alloys by 100 – 150 MPa, limited cast grain refinement (up to formation of as non-dendritic structure), a marked improvement in …
Scandium vs. Aluminum? | Mountain Bike Reviews Forum
That said, "scandium" as a term in frame construction, refers to an aluminum alloy with a small percentage of scandium added to improve weldability. This allows for shorter butts in the tube (eg: less length of increased thickness at the joint) which typically yeilds a more responsive ride.
how do the J frames in scandium and alloy hold up to use?
Re: how do the J frames in scandium and alloy hold up to use. My personal carry is a S&W 340 AirLite Sc. I've had (before Magnaporting) the barrel and shroud come loose from recoil from using factory loaded .357 Mags in 158 grains. Recoil is simply horrible. My advise is to stick with .38 Spcl loads, or SS frames. T.
Scandium vs. Aluminum question | 1911Forum
Scandium is a soft, light metal that might have applications in the aerospace industry. With a cost of $270 per gram ($122,500 per pound), scandium is too expensive for widespread use. Alloys of scandium and aluminum are used in some kinds of athletic equipment, such as aluminum baseball bats, bicycle frames and lacrosse …

S&W J Frame Scandium vs Aluminum | Page 3 | Glock Talk
The J frames were originally .32 Hand Ejector Model, lengthened to accept the .38 Special and .357 Magnum cartridges. It is why they are five shot rather than six shot revolvers. They are very small, alot of people can only grasp them with two fingers on the grip. They are hard to shoot, eliminating weight makes them much more difficult to shoot.
Scandium
An aluminium-scandium alloy has been used in Russian MIG fighter planes, high-end bicycle frames and baseball bats. Scandium iodide is added to mercury vapour lamps to produce a highly efficient light source resembling sunlight. These lamps help television cameras to reproduce colour well when filming indoors or at night-time.
Aluminum or Scandium?
A scandium frame manly consists of aluminum, just like 7005 alloy manly consists of aluminum. Scandium frames are alloy frames which have just been enhanced with a small amount of scandium added to create the scandium enanced aluminum alloy.

Scandium and 7000 series aluminum | Road Bike, Cycling Forums
Sc7000 is simply an aluminum alloy with a small amount of scandium mixed in. There is apparently a great benefit to a frame's integrity using scandium mixed in as the Soviet Union had used it in manufacturing their MiGs. Don't be mislead into thinking that it's pure scandium however.
The Pros and Cons of Aluminum-Framed Handguns
A while back, I acquired a Smith & Wesson 1911SC, scandium/aluminum frame commander sized pistol and I absolutely love it. Lighter to carry, either on my belt or in my vest. Great trigger right out of the box and several very nice "custom" features. Dandy shooter, perhaps even better than my partially accurarized Colt Commander.

derosanorthamericaHow do you make a frame with a scandium alloy?Adding scandium to the alloy improves the grain structure of the final product and makes it easier to weld at the same time. The only other way to make a frame with these alloys is to bond them together (as trek used to do in the late 80s/early 90s for example) with tubes and lugs.durability of scandium frames | Mountain Bike Reviews Forum
mtbrWhy is scandium a stronger alloy than aluminum?Recalculating.... Scandium is alloyed with other metals besides aluminum. As D8 said, it alighns the structure better and makes a stronger alloy. The Rissians discovered this years ago.durability of scandium frames | Mountain Bike Reviews Forum
mtbrDoes a scandium frame have Dings?I've been riding a scandium frame for 6 years with many horrific crashes and the frame is still straight and there are no dings on any of the tubes. Okay, so if that alloy is stronger than 60 series, they should be able to get away with thinner walls, therefore less weight. Is that how it works?

Aluminum will be plastically deformed by stress, and it will not spring all the way back after the stress is removed. That means it will stretch, bend or whatever, in reaction to stress. Don't know what the round count would be, but aluminum frame guns, with or without Scandium, should stretch and eventually become unserviceable.
