About Tungsten Carbide Rings
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 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%.
- Tungsten carbide is the most scratch resistant metal known to man but is not scratch proof.
- Tungsten carbide jewelry is affordable, and has a nice weight to it, like gold and platinum.
- Tungsten rings are quick and easy to remove from your finger in case of medical emergency, easier than gold.
- Tungsten does not bend out of shape due to its hardness, so in an accident the ring will not become deformed where it would injure your finger even more.
- It is hypoallergenic, people with allergies to gold jewelry can wear tungsten jewelry. However it does contain traces of nickel.
- Tungsten wedding bands come in a natural gun metal grey color, but can be plated black, white, or even gold colors.
Some things to take note of
- Just like a diamond, tungsten is very scratch resistant and will not bend out of shape, but it will break if enough shock or pressure is applied to it. This includes dropping it from a height onto something hard like concrete or tiles.
- Due to its hardness, tungsten rings cannot be resized.
- Tungsten carbide is not easily turned back into cash. Gold is traded on the world’s commodities markets and is very liquid. This means anyone can change gold into cash or gold is just like cash. Tungsten is not traded and easily valued if you want to pawn it someday, it will be difficult.
Black tungsten rings are created by plating a standard tungsten carbide band with a black titanium alloy coating which can wear off over time. If needed in the future, the coating can be reapplied for only $20.
