Architectural titanium's elegant, refined beauty is unsurpassed. As a building material it is available in its natural finish or it can be anodized to a spectacular range of colors. And due to its outstanding corrosion resistance, titanium requires no corrosion-preventive coating.

Natural Surface Finish The basic appearance of natural titanium is pleasing due to its soft reflectivity and subtle silver-gray color. The process of annealing and pickling the titanium induces the reflective metallic surface finish.

A Spectrum of Striking, Saturated Colors TIMET meets our customers' color specifications by anodizing the metal and by modifying the natural surface finish prior to anodizing to vary the hue of a color. We process architectural titanium to achieve a variety of surface textures, from a soft matte to a near gleaming reflectivity. The color and finish are inherent to the film and the metal as a result of the anodizing process. When titanium's natural clear oxide film is increased through anodic oxidation, color is created by the phenomenon of light interference - the rainbow principle.

As light rays travel through the film, they are partially reflected, refracted and absorbed. The reflected rays differ in phase, creating interference that gives the titanium color. As the film thickness increases, the color changes - from bronze, to green, to red-violet, through the full range of spectral colors.
