The Material Science and Industrial Genesis of Tungsten Carbide Wedding Bands
The remarkable properties of a tungsten wedding band originate not from a precious metal but from a sophisticated ceramic-metallic compound known as tungsten carbide （WC） a material forged from the elemental tungsten and carbon atoms. Tungsten itself which is also called wolfram is a rare chemical element with the highest melting point of any pure element on the periodic table a property that immediately suggests immense strength and heat resistance.
However pure tungsten is too brittle for jewelry necessitating its fusion with carbon in a process that yields the composite alloy. This alloy is then mixed with a binder metal typically corrosion-resistant nickel which acts as a molecular "glue" to hold the super-hard carbide particles together enabling the final product to be shaped and worn. This compound boasts an astounding 9 on the Mohs scale of mineral hardness
