Anodizing Services
At National Aerospace Processing, we provide NADCAP-accredited anodizing services that enhance the durability and performance of aluminum and metal components used in aerospace and defense applications. Our advanced anodizing processes create a protective layer that improves corrosion resistance, extends component lifespan, and meets strict specifications. NAP ensures high-quality anodized finishes that align with the demanding standards of modern aircraft and defense systems.
Types of Anodizing
Sulfuric Acid Type II, Class I Sodium Dichromate Seal
Sulfuric acid Type II anodizing with a sodium dichromate seal creates a highly durable oxide layer that enhances corrosion resistance for aerospace and military components. Our process strengthens aluminum surfaces, ensuring long-term reliability for mission-critical applications.
Features & Benefits
- Exceptional Corrosion Resistance: Forms a protective oxide layer to withstand harsh environments.
- Enhanced Structural Integrity: Strengthens aluminum surfaces for long-term reliability in aircraft finishing.
- Compliance Ready: Meets aerospace, military, and most OEM specifications.
Sulfuric Acid Type II, Class I Nickel Acetate Seal
This anodizing technique uses a nickel acetate seal to improve corrosion protection and adhesion properties while maintaining a smooth, uniform finish. Commonly used in aerospace metal finishing for components that require both resilience and an aesthetically refined surface.
Features & Benefits
- Advanced Corrosion Protection: Enhances resistance to oxidation and wear.
- Smooth, Consistent Finish: Produces an even surface ideal for metal finishing in aerospace applications.
- Improved Paint Adhesion: Creates an ideal surface for primers and coatings.
AMS2471
AMS2471 aerospace anodizing enhances components with a controlled oxide layer that delivers superior wear resistance and corrosion protection. Our services meet the highest industry standards, ensuring optimal performance and reliability for aerospace applications.
Features & Benefits
- Excellent Corrosion Resistance: Provides a durable barrier against oxidation.
- Improved Paint Adhesion: Ideal for priming and aerospace finishing.
- Consistent Quality: Anodizing process is controlled to meet exacting standards.
MIL-PRF-8625
MIL-PRF-8625 anodizing meets military and aerospace requirements for corrosion resistance and surface durability. This specification ensures optimal performance and enhances component longevity in harsh operational environments.
Features & Benefits
- Military-Grade Protection: Compliant with aerospace and defense applications.
- Thicker Anodized Coating: Increases resistance to wear and environmental factors.
- OEM-Compliant: Meets strict aerospace anodizing requirements.
Now Offering Expanded Anodizing Capabilities
NAP has expanded our services to meet the evolving needs of aerospace, military, and industrial applications:
- TY IIB Anodizing – Provides the same seal options as TY II but with a thinner coating. Designed as a replacement for type 1C anodizing, it offers improved corrosion resistance with reduced thickness.
- Class 2 Anodizing – Available for both TY II and TY IIB with Seal C. While “Class 1” refers to clear color anodizing, “Class 2” indicates a dyed finish. We currently offer red and black as our only color options.
General Aerospace Anodizing Process
The first step of our aerospace anodizing process is meticulous surface preparation, including cleaning and degreasing to remove all contaminants. Components are then processed in our state-of-the-art 16-tank anodizing system, featuring DI water rinse sections for precision treatment. This system allows us to accommodate parts up to 120 inches in length to suit a wide range of aerospace components.
NAP adheres to stringent industry standards, including AMS2471 and MIL-PRF-8625, to ensure high-quality anodizing processes that meet or exceed the specifications of most aerospace OEMs. With rigorous quality control measures, our experts ensure proper coating thickness, optimal adhesion, and superior corrosion resistance.
