Tungsten bar / strip / rod
Tungsten is a non-ferrous metal, is also an important strategic metal, tungsten ore in ancient times is known as “heavy stone”.1781 by Swedish chemist Karl.William.Scheelite was discovered and a new elemental acid, tungstic acid, was extracted. in 1783, tungsten was also extracted from the tungsten deposit discovered by the Spaniard DE purya. In the same year, tungsten powder was obtained for the first time by carbon reduction of tungsten trioxide, and the element was named. The content of tungsten in the earth’s crust is 0.001%. Twenty kinds of tungsten minerals have been discovered. Tungsten deposits are usually associated with the activity of granitic magma. After smelting tungsten is silver white shiny metal, melting point is very high, very hard. Atomic number 74. Steel gray or silver white, high hardness, high melting point, not subject to air erosion at room temperature, the main purpose is to manufacture filament and high-speed cutting alloy steel, superhard die, also used in optical instruments, chemical instruments. Tungsten rod drawn into the wire, can be used as a light bulb, tube and other inside filament.
When the aircraft arrives over the target, it quickly drops its ammunition. Modern munitions are not the same as before, the ammunition used to be heavy explosives, such as tomahawk missiles with 450 kg of TNT, high explosive. Modern warplanes don’t carry much explosives. It changes the way a new concept strikes targets. Instead of using conventional ammunition, they drop a metal rod made of tungsten, called a tungsten rod. From altitudes of tens or hundreds of kilometers, a stick can be dropped at a tremendous speed, enough to sink a destroyer or an aircraft carrier, not to mention a car or an aircraft. So it works with a high degree of accuracy, very fast speed.
