Aluminum Anodizing Process and Finishing Available from D-CHN

Aluminum Anodizing process is the combining science with nature to create one of the world's best metal finishes. For over 40 years D-CHN has been providing aluminum anodizing of components and products to a wide range of industries.

Aluminum anodizing a part is an electrochemical process that thickens and toughens the naturally occurring protective oxide. The resulting aluminum anodize finish, depending on the process, is the second hardest substance known to man, second only to the diamond. The anodic coating is part of the metal, but has a porous structure, which allows secondary infusions, (i.e. organic and inorganic coloring, lubricity aids, etc.).

Where the Finish Always Comes First
When you need to give an aluminum surface the hardness of case-hardened steel while maintaining the light- weight of the aluminum, you need DURALECTRA-CHN. Our custom finishes will make your surface sapphire- hard, corrosion and abrasion-resistant, help it conduct and resist heat, give it lubricity, dielectric properties, and even color it. We make exclusive use of the SANFORD PROCESS�, a proprietary, hard anodizing that is so versatile it enables us to hard coat virtually all alloys (including 2000 series & cast) and to meet your particular requirements.

The anodizing finish is the only one in the metals industry that satisfies each one of the factors that must be considered when selecting high performance aluminum anodize finish:

Durability
Most aluminum anodize processed products have an extremely long life span and offer significant economic advantages through maintenance and operating savings. Anodizing is a reacted finish that is integrated with the underlying aluminum for total bonding and unmatched adhesion.

Color Stability
Exterior anodic coatings provide good stability to ultraviolet rays, do not chip or peel, and are easily repeatable.

Ease of Maintenance
Scars and wear from the aluminum anodizing fabrication, handling, installation, frequent surface dirt cleaning and usage are virtually non-existent. Rinsing or mild soap and water cleaning usually will restore an anodized surface to its original appearance. Mild abrasive cleaners can be used for more difficult deposits.

Aesthetics
Anodizing offers a large increasing number of gloss and color alternatives and minimizes or eliminates color variations. Unlike other finishes, anodizing allows the aluminum to maintain its metallic appearance.

Cost
A lower initial finishing anodized cost combines with lower maintenance costs for greater long-term value.

Health and Safety
Anodizing is a safe process that is not harmful to human health. An anodized finish is chemically stable, will not decompose; is nontoxic; and is heat resistant to the melting point of aluminum (1,221 degrees F.)

Since the anodizing process is a reinforcement of a naturally occurring oxide process, it is non-hazardous and produces no harmful or dangerous by-products.
