Hard Anodize Aluminum Processing Available at D-CHN

Hard Anodize aluminum processing has been provided by D-CHN for over 40 years. We have provided hard anodize aluminum processing for a very wide range on industries.

Hard anodize process, what is it? Developed more than forty years ago, this anodizing method is an electrochemical process that involves placing an aluminum part into an electrolytic bath and applying electrical current through the bath. This process forms an oxide coating (sapphire-hard) on the aluminum part. The oxide coating is built up by a process of anodic oxidation in a cooled acid electrolyte, thus preventing any thermal or physical distortion of precision-engineered components. This oxide coating can be harder than case hardened steel and provide excellent abrasion resistance; it is protective to the aluminum part and can be very durable.

Where the Aluminum Finishing 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.

Today, D-CHN is solving hard anodize finishing problems and supplying quality finishes for all of the following industries:

Medical and Pharmaceutical	Marine Accessories
Consumer Products	Industrial Machinery
Hardware and Tools	Automotive
Computer Components	Military Suppliers
Gears and Pulleys	Advertising Specialties
Writing Instruments	Electronics
Cookware and Serving Pieces	Camping and Hiking Equipment
Cosmetics and Fashion	Aerospace Technologies
AND MORE

The thickness of the anodized piece can be very closely controlled and be applied to a wide variety of parts to suit applications from many industries. Secondary treatments such as impregnation with solid film lubricants and colored dyes are available.

You'll find D-CHN hard anodize parts anywhere you find aluminum surfaces... on the moon, under the sea, in hospitals, schools, laboratories, factories, and in your own home. Hard anodizing is produced by specialist finishing companies, like D-CHN a member of IHAA.

NADCAP Approved Source: We are an approved vendor for the major aerospace and commercial contractors. We certify to government and commercial specifications.

Coating Properties: The coating properties are dependent upon alloy type and the process specification will typically give details of: Thickness, Corrosion Resistance, Hardness & Wear Resistance, Electrical Resistance, Temperature Resistance, and Friction Coefficient after Lubrication.

When you need to give an aluminum surface the hardness of casehardened steel while maintaining the lightweight and strength of the aluminum, you need D-CHN. We make extensive use of the Sanford Process®, a hard anodize process that is so versatile it enables us to hardcoat virtually all alloys (including 2000 series)

The Sanford Process® is the leading technology in the global hard anodizing market. Advantages of the Sanford Process® include the capability of hard anodizing all aluminum alloys, higher abrasion resistance, superior coating hardness and uniformity, higher thermal conductivity and corrosion resistance, and the ability to dye with bright vibrant colors.

Hard Anodize Coating Quality: D-CHN uses the following standards when Anodizing Aluminum (Sulfuric Acid):
MIL-A-8625, Type III, Class 1 and 2, BAC-5821
Class 1 and 2, AMS-2468, and AMS-2469.
For Chemical Conversion Coatings on Aluminum, MIL-C-5541 is used.
Testing for Inorganic Chemical Treatments, D-CHN applies Taber Testing, Coating Thickness, Coating Weight and Salt Spray Testing using an outside testing laboratory.
