What is tungsten carbide? Tungsten is an element that is fused with other materials to become the alloy tungsten carbide. The addition of other metals makes the tungsten carbide harder and more scratch resistant than tungsten alone. This alloy process is similar to the process that iron goes through to become steel. Tungsten carbide has been used in mechanical and industrial applications for many years, and recently has found new life as the longest lasting jewelry material known to man. Manufacturing: Tungsten is ground into a powder and mixed with other metals such as; niobium, tantalum, titanium, chromium, and nickel. The metals are then fused together in an oxygen free furnace, within a die-cast, at over 6,000 degrees Fahrenheit. Interestingly enough, the tungsten itself never melts and mixes with the other metals. Since tungsten has such an extremely high melting point, it can only be heated high enough to “sinter”, or adhere and bond to, the other metals. The nickel within the mixture is referred to as the “binder”, as it assists with the bonding process. Within mechanical and industrial applications, the binder for tungsten carbide is cobalt, but this is not used by reputable tungsten ring sizing manufacturers as it causes oxidation.
