Tungsten is a non-ferrous metal and an important strategic metal. Tungsten ore was called "heavy stone" in ancient times. In 1781 by the Swedish chemist Karl. William. Sheyer discovered scheelite and extracted a new element acid-tungstic acid. In 1783, it was discovered by the Spanish Depuria that wolframite also extracted tungstic acid. In the same year, tungsten trioxide was reduced with carbon for the first time. Tungsten powder, and named the element. The content of tungsten in the earth's crust is 0.001%. There are 20 kinds of tungsten-containing minerals that have been discovered. Tungsten deposits are generally formed with the activity of granitic magma. After smelting, tungsten is a silver-white shiny metal with extremely high melting point and high hardness. The atomic number is 74. Steel gray or silver-white, high hardness, high melting point, not corroded by air at room temperature; the main purpose is to manufacture filaments, high-speed cutting alloy steel, super-hard molds, and also used in optical instruments and chemical instruments[tungsten;wolfram]— —The element symbol W. Wire drawn from tungsten rods can be used as filaments in light bulbs, electronic tubes, etc.
When the fighter plane reaches the sky above the target, it quickly drops ammunition. Modern ammunition is different from before. The ammunition used in the past was heavy explosives. For example, Tomahawk missiles can carry 450 kilograms of TNT explosives and high explosives. Modern fighter planes can't carry many explosives. It has changed a new concept of attacking the target. Instead of using traditional ammunition, it puts a metal rod made of metal tungsten, which is a tungsten rod. From an altitude of tens of kilometers or hundreds of kilometers, a small stick was dropped at an extremely high speed, enough to sink a destroyer or an aircraft carrier. In this way, let alone a car or an airplane. So it can play a role in high precision and very fast speed.
