Titanium ring

Titanium rings are jewelry rings or bands which have been primarily constructed from titanium. The actual compositions of titanium can vary, such as "commercial pure" (99.2% titanium) or "aircraft grade" (primarily, 90% titanium, 6% aluminum, 4% vanadium), and titanium rings are often crafted in combination with other materials, such as gemstones and traditional jewelry metals. Even with these variations in composition and materials, titanium rings are commonly referred to as such if they contain any amount of titanium. Rings crafted from titanium are a modern phenomenon, becoming widely available on the market around the 1990s. Titanium rings offer several unique properties: they are biocompatible (hypoallergenic), lightweight, corrosion-resistant, and have the highest strength-to-weight ratio of any crystalline metal.

Titanium rings offer several unique properties: they are biocompatible (hypoallergenic), lightweight, corrosion-resistant, and have the highest strength-to-weight ratio of any crystalline metal. Anodization of titanium rings is the process whereby an oxide film is formed on the surface of the titanium via an electrolytic process to create color. In the case of titanium rings, this process is performed it is machined into shape. Oxidation changes the ordinary titanium color (generally silver, depending on composition and processing) and increases corrosion-resistance. The anodization process is extremely simple to carry out: the piece is immersed in an electrolyte, cola is popularly used, and a DC voltage, around 100 volts, is applied. The voltage controls the thickness, and thus the colour, of the anodization. .]] Dyes are not necessary to color anodized titanium. The color that results on a titanium ring depends on the thickness of the oxide coating, which is determined by the anodizing voltage. The image to the left shows the color spectrum range that can be achieved by anodizing. The colors, which are simply different wavelengths of light, arise from constructive interference between the light reflected from the surface of the oxide layer and light reflected from the metal surface below. ==See also== Tungsten ring
