One of the most common, and hardest, tungsten compounds is tungsten carbide. Because of its strength when made into compounds, tungsten is used to harden saw blades and make drill bits. It can take around 10 minutes to cut just one drill bit from tungsten using a diamond cutting system, according to the BBC. Some jewelers also use tungsten carbide to make wedding bands and other rings.
Its resistance to heat is helpful when using it in the heating elements for electrical furnaces, spacecraft applications, welding and other high-temperature applications. It was also used in making different types of lighting for this reason. The hotter a filament can get without melting, the brighter the bulb. In 1908 inventor William D. Coolidge discovered that tungsten was an ideal filament material. Today, though, most bulbs use more energy efficient materials. It is still used in X-ray filaments and in electrical contacts of various electronics, however.
