Hard Anodizing of Aluminum Parts from Duralectra
Use
a hard 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 Duralectra. We make
extensive use of the Sanford Process®,
a hard anodizing 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. Developed more than forty years ago, hard anodizing
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: Duralectra
is a NADCAP approved vendor for the major aerospace
and commercial contractors. We certify to government
and commercial specifications Duralectra
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, Duralectra
applies Taber Testing, Coating Thickness, Coating Weight
and Salt Spray Testing using an outside testing laboratory.
