Typically referred to as Type I chromic acid anodizing process entails an electro-chemical treatment process that helps create a thin, supple oxide film on the metal base with high ability to stop oxidation of aluminum surface. Once completed, the thickness of the surface film can range between 0.00005-0.0001 ‘’ resulting an electrically non-conductive aluminum oxide film.

The key ingredient used in Type I Anodizing procedure is chromic acid, which produces a thinner and softer film opposed to Type II or III (hard coat) with advanced forming character. Being highly obstinate to perform against susceptible environment, chromic acid anodizing expert services is used especially for components used in aircrafts, vulnerable to stressful applications. Apart from aluminum, chromic acid anodizing also works excellent with an array of alloy products.

Why Need Chromic Acid Anodizing Expert Services

As said before, Type I or chromic acid anodizing is predominantly demanding in case of critical applications whereas exceptional standard corrosion resistance quality is vital. When it comes to the procedure, it is no difficult or easier than rinse course applies to Type II or sulfuric acid. Oftentimes, however, rinse of parts and getting the desired outcome of anodizing become difficult due to the eccentric configuration of base materials or parts. Sheet metal parts, precision machining components with edges, tiny holes for threading or special cutting are tend to trap chemical solution, which creates rinsing a tricky process. This is where you need support of a chromic acid anodizing expert, who knows if parts are offered necessary treatment prior to the anodizing process, the issue can be effectively eliminated.

With chromic acid anodize, metal pats typically look grayer in color while its thinner film absorbs less amount of tint as dyed. They can be black dyed for employing them as protective and non-reflective layer used on optical components. Opposed to Type II and Type III products finished with chromic acid anodize are softer, lithe and less porous.
