Both titanium and tungsten are considered model metals in the jewelry industry because they were not available to the consumer market as commodities until ten years ago. They have gained tremendous popularity since the introduction and become an integral part of the jewelry material spectrum.
Due to the rather little exposure, many questions arise concerning titanium and tungsten when it comes to choosing jewelry. The followings are some points of consideration if you are seriously thinking about buying a titanium or tungsten wedding ring.
1. Hardness
Titanium and tungsten are both known for the superior hardness over traditional metals such as gold, silver and platinum. One thing worth noting is that it is not the metals themselves in a pure form that possess the hardness, it is their alloys that do. Roughly speaking, the hardest form of tungsten carbide is harder than titanium alloys, and only under extreme circumstances, such as abrasion from diamonds, can it be damaged.
2. Ductility
Titanium is more ductile than tungsten in the common alloys used in jewelry. In other words, when a wedding ring is under high pressure,...
