The two common methods for colorizing Stainless Steel are light interference and titanium coating by physical vapor deposition (PVD)
*Although we do not offer supply only sheets for Ti-Stainless steel, we are happy to custom fabricate based upon your project’s needs. We selectively partner with vendors offering the highest quality materials available in many sizes and thicknesses. Please call or email us for details.Ti-Stainless is a stainless steel sheet metal with with titanium alloy in its coating. There are several methods to achieve color on stainless steel. From the chemical bath process of Interference Stainless Steel to electroplating with tinting agents. Ti-Stainless is one of the most effective methods to achieve a unique tone or color on stainless is through titanium and other alloys applied to the surface of the stainless steel.In its raw sheet form, titanium is an expensive and difficult material to machine and fabricate. It has low ductility. This means that it doesn't want to bend, and that it will typically revert to its form. This is why the titanium-nickel alloy is used as a "memory-metal" for products like eyeglasses. On the other hand, this also means that titanium will take more time to machine when in sheet form.This is where Ti-Stainless has distinct advantages over other raw titanium sheet. Ti-Stainless, also known as titanium-coated stainless steel or generally as PVD stainless steel, is an more economical solution to those desiring a custom color with the longevity of titanium and stainless steel. Titanium-coated stainless steel can come in heavy gauge sheets because it is a thin layer of titanium chemically bonded with a thicker layer of stainless steel. Stainless steel coated with titanium may increase its scratch and corrosion resistance, making its durability superior to many other metal options. This durable titanium-coating makes it a high-quality option for colored metal systems.
Interference Stainless Steel
*Although we do not offer supply only sheets for light interference stainless steel, we are happy to custom fabricate based upon your project’s needs. We selectively partner with vendors offering the highest quality materials available in many sizes and thicknesses. Please call for details.Light Interference Coatings (LIC) on stainless steel provide a broad range of color which changes in various lights. From a deep blacks to bold bright colors, the light interference process brings a whole spectrum to stainless steel. The fine coating adds an aesthetic layer to the metal without sacrificing the innate high-performance qualities of stainless steel.There is no material in architectural use today that equals the iridescence produced by light interference on stainless steel. The effect is made by immersing the material in an acid bath, which forms a chromium oxide film layer on the surface. The acid bath produces interference colors by closely controlling the thickness of the chromium oxide film layer. This oxide film layer is clear, yet remarkable colors are produced by the physics of light interference.The colors generated are those obtainable by separation of the light spectrum. Light reflects off the dual surfaces, the surface of the metal and the surface of the oxide film. Depending on the thickness of the oxide film or the angle of the light reflecting back to the eye, different colors can be obtained. Portions of the light wave are enhanced in relation to other adjacent wavelengths, or portions are counteracted by the misalignment of these wavelengths.
