Aluminum Anodizing

Reid Metal Finishing

A Brief Overview

Aluminum anodizing entails converting aluminum to aluminum oxide and coating a surface with aluminum oxide. This treatment benefits you since it provides superior corrosion resistance/durability, allowing the treated surface to withstand dyeing (for coloring) without compromising the target material. Aluminum anodizing also provides electrical insulation, a critical property in countless machinery that interacts closely with moisture, electrical charge, or both.

With increased chemical resistance comes physical durability. Scratches and abrasions build up in virtually every piece of machinery. While this treatment is not a perfect cure-all, it is a worthy investment that will pay off with lower repair/replacement costs. Lastly, aluminum anodizing permits a surface to act as a base for primer and secondary coatings.

Part shape

There is a direct correlation between the complexity of a shape and the cost to anodize. Many small nooks and crannies require more attention and careful quality control to ensure the anodizing went as planned.

Part size

As you may expect, more surface area costs more to anodize, though if the shape is relatively simple, the per-unit-area cost may be fairly low. If a part is excessively large or bulky, that part could require further specialized preparations and treatment to ensure proper aluminum anodizing treatment.

Part complexity

Part complexity refers to physical complexity and whether or not multiple metals/alloys are exposed on the part surface. The anodizing process accounts for the electrochemical effect that multiple metals or exposed materials might have on the final result. Our expert team ensures that these factors are always considered.

Type of anodizing treatment

Different anodizing treatments have varying costs depending on raw material pricing (primarily chromic and sulfuric acids), labor, and skill sets required for a given treatment, time, and cleaning/disposal of anodizing waste products. Please contact us for a detailed quote.
