Tungsten rod
At high temperature, tungsten alloy rod is a material with high melting point and low thermal expansion coefficient. The addition of tungsten alloy elements improves workability, toughness and welding. The properties of the material are built on tungsten alloy rods in manufacturing to eliminate problems associated with heat treatment of other tool materials.
Tungsten is found in 0.001% of the Earth's crust. Twenty tungsten-bearing minerals have been found. Tungsten deposits are usually formed with granitic magma activity. After smelting, tungsten is a silver-white glossy metal with a very high melting point and great hardness. Atomic number 74. Steel gray or silver white, high hardness, high melting point, at room temperature is not corroded by air; Mainly used in the manufacture of filament and high speed cutting alloy steel, super hard die, also used in optical instruments, chemical instruments.
When the plane reaches the target, it quickly drops its ammunition. Modern munitions are not the same as before, before the ammunition is very heavy explosives, such as Tomahawk missiles can carry 450 kilograms of TNT, high explosive. Modern aircraft, which do not carry much explosives, have changed the concept of striking targets in a new way. Instead of using conventional munitions, they drop a metal rod made of tungsten. This is called a tungsten rod.
Tungsten rods possess special properties, such as low thermal expansion with good thermal conductivity, adequate resistance to electrical resistance, and high elastic modulus. Therefore, tungsten rods are widely used in various fields. Such as support line, import line, printer needle, various electrodes and quartz furnace, filament, high-speed tools, automotive automatic products, sputtering target material.
