Hardcoat Anodizing

Anodized Aircraft Parts

Hardcoat Anodizing (Type III) is performed by submerging the component in an acid bath electrolyte solution. The anodic oxide build up actually penetrates the part or component as much as it builds up on the surface. Some benefits are:

  • Corrosion Resistance
  • Abrasion Resistance
  • Electrical Resistance

Hardcoat Anodizing Capabilities

Type of Process
Hardcoat Anodizing
Component or part gains increased corrosion resistance. Also has greater abrasion and electrical resistance.
Process Approvals
For Hardcoat Anodizing we adhere to:
  • AMS 2482: Hard Coating Treatment of Aluminum Alloys PTFE-Impregnated Or Codeposited
  • CSFS020: Anodize, Chromic Acid, Sulfuric Acid and Hard Coat
MIL-A-8625MIL-A-8625 (PDF - 1627KB)
Anodic Oxide builds up on the part.
Base Materials Worked
Aluminum and aluminum alloys.
Type III - Hard Coatings. Produced by immersing the aluminum components into a low temperature acid bath.
The Hardcoat Anodizing Classes we adhere to are:
  • Class 1 - Non-Dyed
Colors range from light tan to gray/brown, from gold to bronze, and many shades of gray.
Anodizing Thickness
From 12.7µ-115µ. Hardcoat Anodizing actually penetrates the metal as much as it builds up on the surface. So, the term "thickness" actually includes the penetration and build-up.
All Hardcoat Anodizing processes are performed manually to ensure the proper care is given to each step.
Additional Operations
We offer several additional operations that may be required for your product: Cleaning, Magnetic Particle Inspection (NDT), Penetrant Inspection (NDT), Hardness & Conductivity Testing (NDT), Dry Film/Solid Film Lubricants and Primer & Topcoat Painting.

Please let us know if you require any of these additional services.
Quality Control
All processes are subject to our rigorous Quality Assurance process. All work is reviewed and inspected to be in compliance with the specification (Process Approval requested).
Industries Served
We are committed to providing the aerospace and defense industries with the highest quality metal finishing, testing, and painting available.
Environmental Responsibility
As a corporate citizen, we are committed to responsibly protecting our environment. We have a state-of-the-art $2 Million Waste Prevention System in place. All hazardous waste materials are 100% recycled and rendered harmless.

We know that this is important to you, and so we maintain an open door policy concerning environmental inspections of our facility.
With over 50 years in the metal finishing industry, we have the expertise you can depend on.
Minimum Order
We can provide Hardcoat Anodizing for prototype to high volume runs.
