Introduction of Tungsten Rings

Tungsten is a very hard and dense metal, mined from Wolfram ore and symbolized by a (W) on the periodic table of elements. It melts at an extraordinary 6,100 degrees Fahrenheit–the highest melting point of all metals. On its own, tungsten is vulnerable to scratches and damage just like any other metal, such as titanium and steel. Tungsten does not gain its extreme hardness until it is combined with a carbon alloy, transferring it into tungsten carbide (WC) with a hardness between 8.5 and 9.5 on the Mohs hardness scale. Tungsten carbide is four times harder than titanium, twice as hard as steel, is virtually unscratchable, and has been widely used for decades in industrial applications such as cutting tools, mining machinery, and rocket engine nozzles.

So tungsten rings are also can be called as tungsten carbide rings, they are durable enough for every-day use and keep their original polish and luster for life. Tungsten carbide can only be scratched or damaged by extreme measures, like abrasion from diamonds or corundum. Consequently, activities that would normally require the removal of conventional wedding bands for their protection can be performed without concern by the wearer of a tungsten carbide wedding band. While extremely strong and scratch-resistant, tungsten carbide is a bit more brittle than traditional metals used in wedding bands.
