Tungsten Rods, also called tungsten alloy rods, are made by refining metal powders at a specific high temperature using special high-temperature powder metallurgy technology, along with Anviloy 1150. This results in a material with low thermal expansion coefficient, good thermal conductivity, and excellent material properties.
At high temperatures, tungsten rod serves as a material with a high melting point and low thermal expansion coefficient. The addition of tungsten elements increases workability, toughness, and weldability. The material's performance is established in the manufacturing industry, and tungsten rodseliminate problems related to heat treatment of other cutting tool materials.
Tungsten is a non-ferrous metal and an important strategic metal. Tungsten ore was called "heavy stone" in ancient times. In 1781, Swedish chemist Karl Wilhelm Scheele discovered white tungsten ore and extracted a new element, tungstic acid, in a specific high temperature condition. In 1783, Spaniard Don Fausto d'Elhuyar discovered black tungsten ore and also extracted tungstic acid from it. In the same year, tungsten powder was obtained from carbon reduction of tungsten trioxide for the first time, and the element was named. The content of tungsten in the earth's crust is 0.001%. Twenty kinds of tungsten-containing minerals have been discovered. Tungsten deposits generally form with the activity of granitic magma. Refined tungsten is a shiny silver-colored metal with a very high melting point and hardness. Its atomic number is 74. It is gray or silver-white, has high hardness, high melting point, and is not easily eroded by air at room temperature. Its main purpose is to manufacture light filaments and high-speed cutting alloy steel, superhard molds, optical instruments, chemical instruments - its element symbol is W. The tungsten wire drawn from tungsten rods can be used as a filament in light bulbs and electron tubes.
When a fighter jet reaches the target area, it drops its payload quickly. Modern munitions are different from those in the past. In the past, heavy explosive bombs were dropped. For example, a Tomahawk missile can carry 450 kilograms of TNT or high explosives. Modern fighters can't carry much explosive material, so a new concept was introduced targeting the impact on the target: instead of the traditional explosives, a metal rod made of tungsten alloy is dropped, which is the tungsten rod.
Dropping a small rod from tens or even hundreds of kilometers away at extremely high speed is enough to sink a destroyer or an aircraft carrier, let alone a car or an airplane. It can play a role because of the high accuracy at high altitudes and extremely fast speed.
Tungsten rods have special properties as one of types of refractory metals such as low thermal expansion and good thermal conductivity, sufficient resistance to electrical resistance, and a high elastic modulus. Therefore, tungsten rods are widely used in various fields in the form of supporting wires, introducers, printer needles, various electrodes and quartz furnaces, light filaments, high-speed tools, auto products, and sputtering targets.
