Tungsten alloy shot is used as the shot of Saiga-12, for its high density, high hardness and resistance to high temperature.

The Saiga-12 is a 12-gauge shotgun available in a wide range of configurations, visually patterned after the Kalashnikov series of assault rifles. Like the Kalashnikov rifle variants, it is a rotating bolt, gas-operated gun that feeds from a box magazine. All Saiga-12 configurations are recognizable as Kalashnikov-pattern guns by the large lever-safety on the right side of the receiver, the optic mounting rail on the left side of the receiver and the large top-mounted dust cover held in place by the rear of the recoil spring assembly.

The Saiga-12 is manufactured by the arms division of Izhmash, in Russia. It was previously imported into the US by European American Armories, although their agreement expired in 2005 and Izhmash then began exporting through the Russian-American Armory Company. The current export import partner is Wolf Performance Arms. Izhmash also manufactures Saiga 20s and Saiga 410s in 20-gauge and .410 bore, as well as the Saiga semi-automatic hunting rifles in a number of centerfire calibers.

Tungsten alloy shot has increased the lethality of Saiga-12, for its high density, high hardness and other properties.

Tungsten alloy shot is used as the shot for shotgun hunting shells. Tungsten alloy shot is used as the shot of SPAS-12.

The Franchi SPAS-12 is a combat shotgun manufactured by Italian firearms company Franchi from 1979 to 2000. Only five percent (about 1,850) of the estimated SPAS-12 shotguns manufactured were imported into the U.S. The SPAS-12 is a dual-mode shotgun, adjustable for semi-automatic or pump-action operation. The SPAS-12 has been sold to military and police users worldwide, on the civilian market, and has been featured in films and TV shows.

The appearance and intended purpose of the SPAS-12 initially led to its "combat" designation. Franchi renamed the model the Sporting Purpose Automatic Shotgun in 1990, after the importation ban of 1989 (when it was called the Special Purpose Automatic Shotgun). This allowed continued sales to the U.S. as a limited-magazine-capacity, fixed-stock model until 1994. Following the Federal Assault Weapons Ban, exports to the U.S. ceased. In September 2004 the ban expired, but Franchi had already ended production of the SPAS-12.

Using tungsten alloy shot, the force of SPAS-12 is improved.

Tungsten alloy shot is used as the shot for shotgun hunting shells. AA-12 uses tungsten alloy shot as its hunting shot.

AA-12, originally designed and known as the Atchisson Assault Shotgun, is a shotgun developed in 1972 by Maxwell Atchisson. The most prominent feature is reduced recoil. The current 2005 version has been developed over 18 years since the patent was sold to Military Police Systems, Inc. The original design was the basis of several later weapons, including the USAS-12 combat shotgun. AA-12 is fully automatic only but fires at a rate of 300 rounds per minute, making it possible to fire one round at a time with brief trigger pulls. It is fed from either an 8-shell box magazine, or a 20- or 32-shell drum magazine.

Tungsten alloy shot has increased the lethality of AA-12, for its high density, high hardness and other properties.

Tungsten-rhenium wire has room and high temperature strength, good ductility after recrystallization, the resistance rate is high, low resistivity, resistant to oxidation and carburization resistance, "water cycle response" capability and welding performance and good.

Tungsten-rhenium wire is powder metallurgy, machining and electrochemical machining pressure as the main technical expertise to wire with different characteristics, Rod, and products for the product, in order to create a single crystal sapphire as the main application areas, it is the tungsten industry system with high technological content and added value of a branch.

Tungsten-Rhenium Wire Introduction

Abbreviation: Tungsten Rhenium Wire for Sapphire
Tungsten-rhenium wire is a kind of tungsten and rhenium alloy composed of different proportions according to wire.

Common models are: W-3Re (rhenium-containing 3%) W-5Re (rhenium containing 5%) W-20Re (rhenium containing 20%) W-25Re (rhenium containing 25%) W-26Re (rhenium containing 26%)
Wherein the model W-25Re (rhenium-25%), 0.5mm diameter tungsten rhenium wire is widely used in the manufacture of single crystal sapphire.
