There are lots of metals out there, but none of them boast the same unique set of attributes that tungsten carbide does. Carbide is incredibly dense (it’s almost twice as heavy as silver and three times as heavy as iron), has a hardness that rivals diamond, is impervious to heat, rust and scratches and can be molded into many different shapes. It’s no wonder that tungsten carbide is used in so many different applications throughout the world, from the tools used in manufacturing to the undersea equipment required to explore for oil and natural gas.
But what exactly is the melting temperature of tungsten carbide? Tungsten, as mined from Wolframite ore, has the highest melting point of any known element at 6,192 degrees Fahrenheit (3422 degrees Celsius). However, tungsten is also extremely strong and resists a lot of damage, which makes it ideal for use in industrial applications.
Tungsten carbide, which is also known as tungsten cemented carbide or WC, is made by heating tungsten powder with carbon at high temperatures. This process transforms the tungsten into a very hard, dense alloy with a hardness that is 8.5 to 9.5 on the Mohs scale.
Because tungsten is so hard and dense, it can be pressed and shaped into a wide range of components, including tungsten saws and tungsten drill bits. This allows workers to cut through anything, including hardened steel, with relative ease. Tungsten carbide’s strength and durability also allow it to be recycled over and over again, a feat that few other metals can claim.
