Military tungsten alloy cube is usually consisted of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe. The most important property for tungsten alloy cube is that small volume with high density, which means it can be used as counterweight for F-22.

F-22 is a single-seat, twin-engine fifth-generation supermaneuverable fighter aircraft that uses stealth technology. It was designed primarily as an air superiority fighter, but has additional capabilities that include ground attack, electronic warfare, and signals intelligence roles. Lockheed Martin Aeronautics is the prime contractor and is responsible for the majority of the airframe, weapon systems and final assembly of the F-22. Program partner Boeing Defense, Space & Security provides the wings, aft fuselage, avionics integration, and training systems.

The space for counterweight in F-22 is limited. That requires counterweight must reduce its weight significantly. Military tungsten alloy cube has high weight but small value. So it is ideal counterweight for F-22.

Military tungsten alloy cube is usually consisted of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe. The most important property for tungsten alloy cube is that small volume with high density, which means it can be used as counterweight for Type 094 submarine.

The Type 094 submarine is a class of ballistic missile submarine developed by the Chinese People's Liberation Army Navy. The first-of-class was constructed at Huludao Shipyard in Huludao, Liaoning and launched in July 2004. Four submarines are believed to have been constructed.

The Type 094 submarine is capable of carrying 12-16 of the more modern JL-2s with a range of approximately 8,000-12,000 km, and is capable of targeting some of the Western Hemisphere from close to the Chinese coast. The Type 094 is believed to replace the Type 092 submarine (NATO reporting name: Xia class) for the People's Liberation Army Navy.

Using military tungsten alloy cube, Type 094 submarine reaches to a definite magnitude so that can relize immersion.

Compared with lead, the density of military tungsten alloy cube is higher but value is smaller. Otherwise, military tungsten alloy cube is nontoxic. So military tungsten alloy cube is ideal counterweight for Type 094 submarine.

Ballistic missile submarine is a submarine equipped to launch submarine-launched ballistic missiles (SLBMs) with nuclear warheads. In the US Navy they have the designation SSBN and they are nicknamed 'boomers', a common term of art used in everyday briefings and base operations. Virtually all ballistic missile submarines are nuclear powered and are therefore nuclear submarines.

Using military tungsten alloy cube, ballistic missile submarine reaches to a definite magnitude so that can relize immersion.

Military tungsten alloy has high density but small value, so it is quir suitable for ballistic missile submarine.

Submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term most commonly refers to a large, crewed, autonomous vessel. It is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub.

Using military tungsten alloy cube, submarine reaches to a definite magnitude so that can relize immersion.

When purchasing gold jewelry, less costly options exist that give the look of gold without the hefty price. Gold-plated and gold-filled jewelry are two options that feature a base metal and a layer of gold, which gives the appearance of gold but not the price tag.

Gold-filled Jewelry
Gold-filled jewelry uses a technique in which thin layers of gold are bonded by heat and pressure to a brass center. Several layers of a core metal are surrounded by at least 10k gold. Jewelers usually note the ratio of gold to base metals. United States requirements state that gold-filled jewelry must contain no less than 1/20 its weight in gold.

Gold-plated Jewelry
Gold-plated jewelry has a thin molecule of gold overlaying a base metal such as zinc, copper or nickel. This thin layer is not 14k and usually wears off the base within a short period of time. Jewelry makers utilize an electrochemical process to bind the thin layer of gold to the base metal. Gold-plated jewelry may contain varying thicknesses of gold.
Pros and Cons of Gold-filled Jewelry
Gold-filled jewelry lasts much longer than gold-plated jewelry. The gold used is at least 10k gold, unlike gold-plated jewelry, which contains less than 10k gold. The bonding process and layers make the jewelry more durable. If you plan to wear a jewelry piece frequently, you should choose gold-filled over gold-plated. The only drawback is that gold-filled jewelry will be more costly initially.

Pros and Cons of Gold-plated Jewelry
The thin layer of gold-plated jewelry is soft and easily scratched. Therefore, jewelers such as Gem Fashion do not recommend wearing gold-plated jewelry on a frequent basis. Skin oils and the environment eventually wear off the gold layer. However, gold-plated jewelry is less expensive than gold-filled jewelry.

History
Gold jewelry has been popular since the days of ancient Egypt and Greece. Rolled or filled gold experienced popularity during the Victorian era because the gold-filled jewelry was more affordable for the middle class. During the Edwardian era, the popularity of smaller pieces made gold-filled jewelry less popular. A resurgence in popularity occurred during the Retro or Retro Modern period of the 1930s. When the U.S. Department of Commerce began restricting gold-filled jewelry to jewelry with at least 20 percent gold, gold-plated jewelry gained popularity.

There are several ways that gold jewelry is made, and normally the gold content is noted somewhere on the jewelry in a 14K format. There are varying degrees of karats of gold, but by itself, gold as a pure metal is too weak to make jewelry. It is combined with an alloy metal such as nickel to make the metal strong enough to make jewelry. If there is no notation as to the degree of gold in a necklace, there are a few home remedies that you can try to test your gold and see whether it is real.

1.Test gold by looking at the "gold" in the sun. Gold should retain its color in the sun as well as the shade. Many metals glitter in the sun, but gold isn't one of them.

2.Stick a sharp needle or pin in the gold. If it fractures or cracks, it isn't gold. Gold is malleable, meaning it can bend and be dented but it doesn't crack easily.

3.Gold is heavy. It will sink to the bottom and stay there. If you are gold panning, a great test is to rock the pan back and forth with some water. Gold should stay at the bottom and not move around much.

4.A sure-fire way to test gold is to wear it on your skin. If your skin turns a greenish color, that isn't gold you are wearing, but more likely another metal with possibly a bit of gold content. A pure gold piece of jewelry will not react with skin.

5.Try running a magnet over the "gold." Precious metals like gold and silver are not magnetic, so if your "gold" is attracted by the magnet, that isn't a good sign. Of course, if it isn't, that doesn't guarantee it is gold. Lots of things are nonmagnetic, like wood.

6.The best way to test gold is to take it into an expert to be tested. Experts have sophisticated acid tests that can determine the exact gold content and tell you the gold price per gram and how much your item is worth.
