Tungsten

About 50% of the tungsten ore mined in the world is used for smelting high-quality steel, about 35% for producing hard steel, about 10% for making tungsten wire, and about 5% for other purposes. Tungsten has a wide range of applications, and the most common one is tungsten carbide (WC) cemented carbide. Such hard alloys are commonly used as durable metals in metal processing, mining, oil extraction and construction industries. In addition, tungsten filaments are also widely used in light bulbs and vacuum tubes. Tungsten is also commonly used as an electrode. Tungsten is extremely hard and compact, making it an ideal choice for making heavy metal alloys. Such alloys are used in armor, heat sinks, and high-density applications such as heavy objects, balancing heavy objects, and heavy objects for ships and aircraft. Because tungsten is very dense, darts often contain 80% to 97% tungsten. High-speed steel contains tungsten, sometimes 18% tungsten. High-temperature alloys used for manufacturing turbine blades, durable parts and protective layers contain tungsten (such as Hastelloy, tungsten-chromium-cobalt alloy, etc.). Compounds of tungsten can be used as catalysts.
