Typical applications for tungsten rods include counterweighting and balancing of aircraft control surfaces and rotor blades, guidance platforms, balancing of flywheels, turbines and engine crankshafts, damping governors, filament and fuse masses. Other applications include radiation shielding, gyro rotors, weapons (including armor-piercing applications) and high-temperature tools.
1. Tungsten rods are mainly used as ingredients for casting materials, cutting tools and cutter heads, tungsten wires and thermal conductors for lighting instruments, high-end automobile crankshafts and cylinder barrels, and various heat-resistant steels. Tungsten rods are also used in the manufacture of guns, rocket launchers, satellite aircraft and ships.
2. Tungsten rods are also used in the manufacture of guns, rocket launchers, satellite aircraft and ships.
3. Because tungsten has the characteristics of high temperature resistance and low pollution, it is widely used in the production of crucibles and accessories for ruby sapphire crystal growth and rare earth smelting in the LED industry.
4. Mainly used in casting materials, cutting tools and cutter heads, thermal conductors, as materials and additives, crankshafts and cylinder barrels of advanced automobiles, components of various heat-resistant steels and electrodes, mainly used in guns, artillery, rockets, satellites, Aircraft and ships.
5. Tungsten rods are used as materials for making special steel and tungsten wires, or for electrical contact points. Use tungsten rods containing impurities to process light bulb filaments or electronic tube filaments to ensure excellent high temperature resistance.
