Tungsten Carbide Rings
From Pros & Cons to Facts & Myths:
Tungsten comes from a Swedish term meaning "heavy stone." Tungsten's chemical symbol “W” comes from its earlier name, wolfram. Wolfram comes from the mineral wolframite, in which it was discovered. Wolframite means "the devourer of tin" since the mineral interferes with the smelting of tin. Tungsten has the highest melting point of all metals at an astounding 6,191.6 degrees Fahrenheit. Tungsten is rated at about a 9 on the Mohs scale of hardness. A diamond, which is the hardest substance on earth, is rated at a 10. Tungsten carbide is about 2 or 3 times harder than titanium and cobalt chrome. Tungsten carbide wedding bands are the top selling metal for men’s wedding bands in America today.
"Tungsten rings are indestructible." This is not true. For some reason, many people associate tungsten’s ability to withstand scratching, as proof that it is indestructible. There are dishonest companies posting videos online showing tungsten rings being hit by a hammer and not breaking. These are either edited or they are not really hitting it that hard. Tungsten’s hardness is what makes it so resistant to scratching. That same level of hardness also means that it won’t bend, but it will break or crack if enough force is applied to it, kind of like a diamond. "You want a pure tungsten carbide ring." Pure tungsten carbide rings are not possible. Tungsten carbide by itself is a powder. You need a binder, like nickel, to hold it all together to form a shape. It is kind of like a granola bar. You need the sugar or honey to have all the grains stick together to form the shape of a bar. The ideal amount of tungsten carbide to make jewelry is about 85%.
