/Black tungsten carbide ring: there is supposed to be the test from scratch?
Titanium Kay I bought to replace his former band. Http: / / www.titaniumkay.com/Black-Tungsten-Carbide-7mm-Flat-Wedding-Ring-P103262.html It's been three weeks and is badly scratched, revealing the silver underneath. He works with computers, so nothing hard in the ring. I called the company and sent to another, but now I'm worried that the same will happen with the new! Is it a myth that tungsten carbide is not zero? Someone else has experience with a tungsten carbide black scratch? Thank you!
Tungsten carbide (WC) is always black or gray-black. It is as hard as corundum and could be scratched with emery (corundum), although it would be a lot of work. You can, of course, be lined with diamond. On the website, it says that the folder is nickel. That means that grains Toilet fixed in 10% (guess) of Ni it is soft. Perhaps it is not properly annealed.
