Fact about the material Tungsten Carbide
"Tungsten" (from the Swedish and Danish tung sten, means "hard-" or, more accurately, "heavy-stone") is used in English, French, Italian as the name of the element, although in many other languages (e.g. in German and Spanish) it is known as "wolfram", and this is also the origin of its chemical symbol, W and the atomic number is 74. Tungsten carbide, WC, or tungsten semicarbide, W2C, is a chemical compound containing tungsten and carbon. Colloquially, tungsten carbide is often simply called carbide. Our Tungsten Carbide Rings are composed of 85-88% of Tungsten Carbide, with a minority composition of materials including Tantalum, Titanium, Niobium and Chromium.
In its raw form, tungsten is a steel-gray metal that is often hard to work. Of all metals in pure form, tungsten has the highest melting point (3,422 °C, 6,192 °F), lowest vapor pressure and (at temperatures above 1,650 °C) the highest tensile strength. Tungsten has the lowest coefficient of thermal expansion of any pure metal. It is remarkable for its robust physical properties, especially the fact that it has the highest melting point of all the non-alloyed metals and the second highest of all the elements after carbon.
Tungsten Carbide Jewelry
Tungsten Carbide is the only metal that can be permanently polished and scratch-free. The polish and finish will virtually last forever and will never deform. It is 10 times harder than 18k gold, 5 times than steel and 4 times than titanium. Many people also enjoy the heavy weight of a tungsten carbide ring. The enduring polish of a tungsten ring together with the solid weight, speak of commitment, security and an everlasting bond.
