COATINGS FOR ALUMINUM & MAGNESIUM

IHC PRIMARY COATINGS

Anodize

Anodize

Conventional anodize, or Type II anodize, is an anodic coating that converts the surface of the aluminum to aluminum oxide. This generally clear aluminum oxide layer provides excellent corrosion resistance, moderate durability, good adhesion for painting or bonding, and excellent coloring options. This coating is typically about 10-20 µm (.0004 - .0008 inches) thick with only about 1/3 of that thickness as buildup per surface. Common applications are structural and architectural products, gage handles, door hardware, flashlights, fasteners, washers, dials, knobs, and mobile device housings.

Hardcoat

Anodize

Hard anodize, or Type III anodize, is a variation of the conventional anodize process that yields highly wear-resistant coatings. While still providing outstanding corrosion resistance and acting as a good base coat, hardcoat is also extremely abrasion resistant and is commonly referred to as "file hard." Hardcoat is generally a darker coating and does not offer the coloring options of conventional anodize. Coatings are typically 25 - 50 µm (.001 - .002") thick with 1/2 of the thickness as buildup per surface. Common applications include brake caliper pistons, transmission valves, cookware, firearms, tooling and fixtures, and molds.

Chromate Conversion Coatings

Hexavalent and trivalent chromate conversion coatings on aluminum offer good corrosion resistance and bonding properties. Although they are not very durable they do maintain electrical conductivity allowing them to be used in applications where anodize or hardcoat are not suitable. These essentially immeasurably thin coatings are offered in the traditional hexavalent form or the more recent trivalent form to comply with more recent environmental regulations. These coatings are often used in conjunction with anodize and hardcoat to maintain conductivity in certain areas while still providing protection.

Anomag™

Similar to a Type II anodize on aluminum, Anomag provides excellent corrosion resistance and an outstanding bonding surface. Because of its bonding ability and ease of absorption of dirt and oils it is generally not used as a final finish but is used as a base coat for painting or e-coat. Typical coatings are 5-20 µm thick. Applications include structural components, frames, and housings.

Pixodize™

Anodize

Pixodize is a breakthrough graphic anodizing process that goes way beyond the limitations of single color conventional aluminum anodizing processes. Pixodize opens up whole new possibilities for anodized or hardcoated products by infusing virtually any digital image into the coating. If you can picture it, we can Pixodize it. Just like traditional colored work the digital image will be integral to the anodize coating. With no additional buildup over the base anodic coating, it will not peel, flake, or chip off like other topcoat graphics. All this while meeting military, commercial, and industrial specifications make Pixodize the graphic process of choice.
