Walgren hard coat and other anodize processes impart superior wear resistance and exceptional dielectric properties; they also produce a non-conductive surface with homogeneous porosity.

Walgren anodizing technology used in aerospace / military applications includes Type I, II, III, phosphoric and Oxalic Acid. Tartaric, Boric Sulfuric and Thin Film Sulfuric are often specified as chrome alternatives. In addition to anodize technology, Walgren supplies the sector with systems for Alodine chromate conversion coating as well as in-line nondestructive testing packages, including fluorescent penetrant inspection.

OEMs and military suppliers specify the anodizing process for its performance and versatility. They choose Walgren because our anodizing equipment has an unrivaled track record for reliability and performance, and our management and technical team is the most experienced in the world for the adaptation of anodizing technology to the specialized needs of aerospace and defense.
