our new tungsten ring should last for a lifetime and always look great! There are a just a few points to keep in mind to ensure your ring stays in it's pristine condition for years to come.

Do not drop your ring on a hard surface or purposely hit it with hard metal tool, such as a hammer.

Do not clean your tungsten ring in a jewelers ultrasonic cleaner, or with a steam cleaner or ionic cleaner.

DO not clean your tungsten ring with any chemicals as this can cause spotting.

DO only clean your tungsten ring with a mild soap and water. This will remove dirt, grime, lotions and keep your ring sparkly clean!

Also known as wolfram, tungsten is a chemical element with the chemical symbol W and atomic number 74. The word tungsten comes from the Swedish language tung sten directly translatable to heavy stone, though the name is volfram in Swedish to distinguish it from Scheelite, in Swedish alternatively named tungsten.A hard, rare metal under standard conditions when uncombined, tungsten is found naturally on Earth only in chemical compounds. It was identified as a new element in 1781, and first isolated as a metal in 1783. Its important ores include wolframite and scheelite.

The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all the non-alloyed metals and the second highest of all the elements after carbon. Also remarkable is its high density of 19.3 times that of water, comparable to that of uranium and gold, and much higher (about 1.7 times) than that of lead. Tungsten with minor amounts of impurities is often brittle and hard, making it difficult to work. However, very pure tungsten, though still hard, is more ductile, and can be cut with a hard-steel hacksaw. Tungsten’s many alloys have numerous applications, most notably in incandescent light bulb filaments, X-ray tubes (as both the filament and target), electrodes in TIG welding, and superalloys. Tungsten’s hardness and high density give it military applications in penetrating projectiles. Tungsten compounds are most often used industrially as catalysts.

In the aerospace industry applications. China developed the first generation of tungsten heavy alloy performance good in the 1960s, since immediately after the birth of self-developed China's first artificial satellite navigation device has been successfully applied, then this new material has the first in China an intercontinental missile and developed by a variety of new fighters, helicopters, has been successfully applied. Developed to meet the needs of Chinese communications satellite, but also successfully developed a new type of density up to 18.5g/cm3 high proportion of tungsten-based alloys. A variety of high-performance W-Cu alloys in the rocket (missile) combustion chamber, nozzle, throat, rudder and other parts of the development of high temperature has been applied.

Military industrial applications. China has successful developed the W-Ni-Fe heavy alloy, provides of a variety of wear, shaped charge of the development a key material. W-Ni-Cu heavy alloys also play an important role in doing gyrorotor high proportion of material in China's first nuclear submarine of the research and development.

In the civilian industry and nuclear industrial applications. In the nuclear power industry, used for nuclear reactor insulation and shielding materials, tungsten heavy alloy has a good prospect. In civilian industry, high-density tungsten alloy has been more widely used; mobile phones and golf oscillator rod weight will be a wide range of products. Processing done in the electric performance of the anvil block material to make electrical upsetting of hundredfold increase production efficiency, has significant economic benefits.

In summary, the development of tungsten processing industry does not only play a very important role in building on the national economy, also has a significant impact on the modernization of national defense.

The predecessor of Al-Khalid main battle tank (MBT) is 90-II which is developed in China. Al-Khalid MBT is equipped by composite armor and rolling homogenous armor. The tank can perform night operation which is also equipped by thermal imaging system. The main weapon of Al-Khalid MBT is a 125mm caliber smoothbore gun which carrying 39 ammunitions. The smoothbore gun can launch depleted uranium (DU) ammunition, tungsten alloy penetrators, kinetic energy cartridge and high explosive grenade. Otherwise, there are 12.7mm caliber machine gun and 7.62mm caliber machine gun in the tank.

In recent years, Pakistan Army is modernizing Al-Khalid MBT. They attempt to modernize the tank to the most advanced tank in the world. Al-Khalid MBT is called as Super Al-Khalid MBT after modernization, which is equipped by integrated battle management system (IBMS) and active protection system. For the new design of structure, the armor of new tank can endure the strike from all of 120~125mm caliber anti-tank shells who are on service at present. What’s more, the fire control is more advanced, and the firing rate of main artillery has been improved by 9 shells per minute. Meanwhile, Super Al-Khalid MBT is also equipped by Sagem the third generation thermography made in France, laser sight, anti-tank missile tracking system and Valta electro-optical countermeasures device made in Ukraine.
