Hardcoat Anodizing of Aluminum Parts Available at D-CHN

Hardcoat Anodizing of aluminum parts has been provided by D-CHN for over 40 years. We have provided hard anodizing processing for a very wide range on industries.

Use a hardcoat anodizing process when you need to give an aluminum surface the hardness of casehardened steel while maintaining the lightweight and strength of the aluminum, For that, you need D-CHN. We make extensive use of the Sanford Process®, a hardcoat 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 coat 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.

Today, D-CHN is solving hardcoat anodizing 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

Developed more than forty years ago hard anodize 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.

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.

Hard Anodizing Quality: D-CHN is a NADCAP approved vendor for the major aerospace and commercial contractors. We certify to government and commercial specifications 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. Testing for Inorganic Chemical Treatments, D-CHN applies Taber Testing, Coating Thickness, Coating Weight and Salt Spray Testing using an outside testing laboratory.
