Tungsten is a chemical element, also known as wolfram, and it has some pretty amazing properties. Out of all the metals, tungsten has the highest melting point and the highest tensile strength. It is extremely durable and somewhat rare.But tungsten wedding bands are not made out of pure tungsten-instead they are made out of tungsten carbide.Pure tungsten is too difficult to work with, so tungsten that is used for industrial applications-and in jewelry-is compounded into its carbide form.ungsten is a chemical element, also known as wolfram, and it has some pretty amazing properties.
