Does Tungsten Carbide rust? Is there a rust-proof Tungsten ...

Jul 26, 2009· Tungsten carbide does not rust. 'Rusting" in general refers to the chemical reaction of a metal or alloy with something in the environment, causing the metal to be attacked and degrade. Iron, for example, is attacked slowly by oxygen to form iron oxide, which we know as the classic rust.

Are Titanium and Tungsten wedding rings for life?

Titanium rings which are very strong and durable, but they could be scratched like gold or silver rings. Tungsten is totally resistant to abrasion. Being one of the hardest metals known to man, tungsten carbide rings are virtually scratch proof. Can it be bent? With a tungsten ring you never have to worry about it bending out of shape.

Tungsten Rings FAQ | Frequently Asked Questions

In tungsten carbide, hardness is dictated by the oxygen content and the alloying binders. The ideal mixture is a percentage of tungsten at 89%, a nickel alloy at 10% and other carbon elements at 1%. We intentionally avoid less tungsten because this make the ring less durable and prone to scratching.

Tungsten carbide - Wikipedia

Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments ...

Carbide - Wikipedia

In chemistry, a carbide is a compound composed of carbon and a less electronegative element. Carbides can be generally classified by the chemical bonds type as follows: (i) salt-like, (ii) covalent compounds, (iii) interstitial compounds, and (iv) "intermediate" transition metal carbides. Examples include calcium carbide (CaC 2), silicon carbide (SiC), tungsten carbide (WC; often called ...
