Military tungsten alloy swaging rod is made of tungsten alloy rod through calcinations. The normal method used in the processing are extruding, forging and sintering. After calcinations, tungsten alloy swaging rod has higher ductility, toughness and tensile strength than tungsten alloy rod, so it can be used for a longer time. Military tungsten alloy swaging rod can be used for S-125.

The S-125 Neva/Pechora Soviet surface-to-air missile system was designed by Aleksei Mihailovich Isaev to complement the S-25 and S-75. It has a shorter effective range and lower engagement altitude than either of its predecessors and also flies slower, but due to its two-stage design it is more effective against more maneuverable targets. It is also able to engage lower flying targets than the previous systems, and being more modern it is much more resistant to ECM than the S-75. The 5V24 (V-600) missiles reach around Mach 3 to 3.5 in flight, both stages powered by solid fuel rocket motors. The S-125, like the S-75, uses radio command guidance. The naval version of this system has the NATO reporting name SA-N-1 Goa and original designation M-1 Volna (Russian Волна – wave).

With military tungsten alloy swaging rod, S-125 can destroy aircrafts effectively, for its high density, excellent hardness and superior ultimate tensile strength.

The S-25 Berkut  is a surface-to-air guided missile, the first operational SAM system in the Soviet Union. Its NATO reporting name is SA-1 Guild. It was used only to defend Moscow, while the more mobile S-75 (SA-2 Guideline) would be used in almost all other roles. Other names include the R-113 (target acquisition radar), B-200 (target engagement radar), A-11/A-12 (antennas for B-200), and V-300 (a SAM); S-25 is for Systema 25, referring to the system as a whole.

The S-75 Dvina is a Soviet-designed, high-altitude air defense system, built around a command guided surface-to-air missile. Since its first deployment in 1957 it has become the most widely deployed air defense system in history. It scored the first destruction of an enemy aircraft by a surface-to-air missile, shooting down a Taiwanese Martin RB-57D Canberra over China, on October 7, 1959, hitting it with three V-750 (1D) missiles at an altitude of 20 km (65,600 ft). The success was attributed to Chinese fighters at the time in order to keep the S-75 program secret.

Issued in one ounce, half-ounce, quarter-ounce and tenth-ounce sizes, gold eagles (or more accurately American Eagle Gold Coins) are 22 karat (.916 fine) coins struck at the West Point Mint and forged from gold mined in the United States. They are available in three formats: bullion, proof and (since 2006) uncirculated. Since their introduction in 1986, gold eagles have been a hit with investors, with over 13 million of the one-ounce bullion coin being distributed as of November 2010. Gold-plated reproduction eagles have appeared on Internet auction sites, but collectors should have little difficulty in distinguishing these from the genuine article

1.Examine the coin to see if it has the word "copy" stamped upon it in tiny letters. This appears on the more honest of the reproductions.

2.Use a jeweler's loupe to scrutinize the design (Liberty striding forward, by Augustus Saint-Gaudens, the same image that appeared on the double eagle of 1907). Liberty's gown and hair should be crisply realized, especially on the proof and uncirculated coins, which are made with multiple strikes to achieve a meticulous finish. No gold-plated reproduction can hold that degree of detail.

3.Weigh the coin on a pair of digital scales. Every gold eagle bears a denomination expressed as weight in ounces. Make sure that the denomination and the actual weight match up. On fakes, they won't.

4.Look carefully at the accompanying documentation and packaging. Proof and uncirculated gold eagles should be sealed within plastic capsules mounted in satin-lined velvet presentation cases. Each has a certificate of authenticity. The only avenue for bullion gold eagles to be sold to the public is through an authorized dealer. Check if the current owner is such an authorized person, or has a bill of sale from one.
