Aluminium–scandium alloys (AlSc) are aluminum alloys that consist largely of aluminium (Al) and traces of scandium (Sc) as the main alloying elements.In principle, aluminium alloys strengthened with additions of scandium are very similar to traditional nickel-base superalloys in that both are strengthened by coherent, coarsening resistant precipitates with an ordered L1 2 structure.
The Smith & Wesson Model 327PD is an eight-shot double-action revolver that has a 4-inch stainless steel barrel with no muzzle brake or ports. It has a scandium alloy frame and a titanium cylinder. It comes with rosewood Hogue grips. It uses a light-gathering HI-VIZ front sight and an adjustable V-notch rear sight.
In 2001 an aluminium-scandium alloy framed version was introduced in .357 Magnum designated as the Model 340. This revolver weighs 10.9 ounces. [2] The model M&P 342 was introduced in 2001 as a special run of revolvers that are identical to a Model 340 but chambered only for .38 Special +P due to some police departments ammunition restrictions.

Smith & Wesson Model 340PD—first revolver made of scandium alloy, very light, possibly the final evolution of the classic J-frame Chief's Special introduced over 60 years earlier, weighs 12 ounces (340 g). [40] Smith & Wesson Model 617—An 8-shot .22 L.R. revolver with 3" barrel, the frame and cylinder are made from lightweight alloy.
It has a frame constructed of scandium enhanced aluminum alloy, a titanium alloy cylinder, and a corrosion resistant steel barrel liner. Unloaded it weighs only 12 ounces (340 g) and when loaded remains under 1 pound (0.45 kg). [2] With no external hammer it operates double action only.
The alloy Al 20 Li 20 Mg 10 Sc 20 Ti 30 is as strong as titanium, light as aluminium, and hard as some ceramics. [60] Some items of sports equipment, which rely on lightweight high-performance materials, have been made with scandium-aluminium alloys, including baseball bats, [61] tent poles and bicycle frames and components. [62]
The rear sights are fixed; similar to those found on the small J-Framed .38 Special and .357 Magnum as well as the medium-sized K-frame service revolvers.
