Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited for anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized. The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum oxide is not applied to the surface like paint or plating, but is fully integrated with the underlying aluminum substrate, so it cannot chip or peel. It has a highly ordered, porous structure that allows for secondary processes such as coloring and sealing.
Unlike organic coatings, anodization enhances the native crystalline structure of aluminum. It yields a surface hardness comparable to sapphire, providing unparalleled abrasion resistance. In demanding sectors like aerospace and medical devices, anodizing preserves tight dimensions while offering superior dielectric properties, thermal dissipation, and non-outgassing properties under extreme conditions.

Understanding the micro-structure and technological standards of oxide film growth.
Anodizing is completed within an acid electrolyte bath where the aluminum component acts as the anode, and a cathode is connected to the negative terminal of a direct current source. When current is passed, water molecules are split, releasing oxygen ions at the surface of the aluminum. These ions fuse with the aluminum to form a thin, highly structured, porous aluminum oxide (Al₂O₃) layer. The thickness of this oxide coating determines the end-use capabilities of the component.
| Finish Type | Electrolyte Acid | Film Thickness | Primary Characteristics | Applications |
|---|---|---|---|---|
| Type I (Chromic) | Chromic Acid | 0.5µm - 2.5µm | Thinnest coating, self-healing, minimal fatigue impact | Aerospace structural frames, fatigue-sensitive aircraft parts |
| Type II (Sulfuric) | Sulfuric Acid | 5µm - 25µm | Highly porous structure, excellent dye absorption, corrosion resistance | Consumer electronics, automotive levers, cosmetic enclosures |
| Type III (Hardcoat) | Sulfuric Acid (Low Temp) | 25µm - 100µm+ | Extreme wear resistance, high hardness (up to 65 Rockwell C) | Hydraulic cylinders, military valves, marine gear housings |
| Chemical Conversion (Alodine) | Chromate/Non-Chromate | Molecular Scale | Conductive surface finish, excellent base for paints | Electrical shielding boxes, grounding plates |
Historically, hexavalent chromium was used as the industry standard for sealing anodized parts to maximize salt-spray corrosion protection. Today, our engineering team has optimized green alternative processes, including trivalent chromium conversion (TCP) and hot nickel-free demineralized water seals. These methods guarantee compliance with RoHS, REACH, and other environmental mandates without sacrificing corrosion metrics (meeting up to 240 hours of neutral salt spray per ASTM B117).
Providing custom-tailored surface solutions for various highly-regulated fields.
Exposed to abrasive subterranean particulate matter and corrosive gases. Our Type III hardcoat anodizing for fire and gas safety detection sensors, flame sensors, explosive and toxic gas detectors, and hydrant pit box enclosures prevents early wear and mechanical failure.
For high-altitude performance, weight reduction is critical. We manufacture turbine inlets and transmission components out of lightweight aluminum alloys, applying a precision-controlled Type I or Type II finish that retains fatigue strength while resisting extreme temperature differentials.
E-Bike connectors, levers, and tubes demand high aesthetic appeal combined with weather resistance. Our colored Type II sulfuric anodization delivers deep, UV-stable pigments alongside resistance to perspiration, road salt, and physical impact.
Components such as tabletop cooking stoves and cream whippers require non-toxic, non-reactive surfaces. Our food-grade hot water sealing and electro-polishing processes prevent bacterial buildup and withstand high-alkaline commercial washing detergents.
