Tungsten Carbide Education: What is Tungsten Carbide. Tungsten carbide (WC) is durable and hard, it is four times harder than titanium, ten times harder than ceramic and twice as hard as stainless steel, so it cannot be resized.
Description: Named from the Swedish word meaning heavy stone, tungsten is a gray-white metal that is stable and unaffected by air, acids or bases. It has the highest melting point of any element and often is used in alloys that must resist great amounts of heat, such as light-bulb filaments. Tungsten also is used in television tubes, paints, high-temperature lubricants, tanning leather and fluorescent lighting.
