Anodizing Sourcing Across Asia
Type II and Type III hardcoat anodizing for aluminum parts, sourced from vetted manufacturers across India, China, Vietnam and Thailand, with color matching, coating verification, and logistics handled for you.
Your trusted partner for anodizing sourcing
Anodizing looks simple on a spec sheet, coating type, color, done, but the result depends on tank chemistry, rack contact points, and dye consistency staying controlled from batch to batch. AASA connects U.S. businesses with overseas anodizing partners across India, China, Vietnam, and Thailand that hold that control, matched to your alloy, coating type, and whether the part needs Type II color anodizing or Type III hardcoat for wear resistance.
We stay involved past the initial factory match. AASA reviews your drawing for masking needs on threads, bores, or press-fit features, confirms color and coating thickness against a sample before full production, and monitors consistency across the run. Every order is inspected before it ships, and freight and customs are coordinated through the same team, so a batch of anodized brackets or housings arrives matched, verified, and ready to use.

Comprehensive anodizing capabilities
Anodizing covers more than color. Coating type, hardness, and sealing method all change based on whether a part needs to look right or perform under wear. AASA sources across the capabilities below, and factory selection is based on the coating type and testing your part actually requires.
Conventional anodizing for corrosion resistance and cosmetic finish, the standard choice for color and general-purpose parts.
Thicker, denser coating for wear resistance and surface hardness on functional and sliding-contact parts.
Dye immersion after the anodic coating forms, matched to standard colors or a supplied reference sample.
Pore-sealing processes that lock in color and maximize corrosion resistance of the finished coating.
Precision masking of threads, bores, and electrical contact points to keep critical features coating-free.
Eddy current thickness testing, adhesion checks, and salt spray testing to confirm coating meets your spec.
Send your drawing or spec and we'll come back with a factory match and a quote in 48 hours — no obligation.
Join the manufacturers already sourcing anodized aluminum parts through AASA.
Anodizing is an aluminum finishing process, and the alloy underneath changes how the finished coating looks and performs. Some alloys anodize clear and consistent, others carry a natural tint or favor function over cosmetics. AASA sources anodizing across the alloys below and can advise on the right fit for your part.
- 6063 - Clearest cosmetic finish
- 6061 - Structural, consistent color
- 5052 - Corrosion resistant sheet
- 7075 - High strength, hardcoat
- 2024 - Aerospace, functional tint

Direct Factory vs Sourcing Through AASA
Reduce sourcing risks, simplify supplier management, and gain access to a vetted network of anodizing partners across India, China, Vietnam, and Thailand, all through a single point of contact.
Direct Factory
- Limited to the tank capacity and color range of one factory
- Time-consuming supplier research and qualification
- You manage engineering communication
- Quality oversight depends on your internal resources
- Need to coordinate production updates yourself
- Limited alternatives if production issues occur
- You handle supplier negotiations
- Separate management of logistics and export documentation
- Multiple contacts across different vendors
- Higher risk when sourcing from an unfamiliar supplier
AASA Sourcing
- Access to a network of vetted anodizing manufacturers across Asia
- Factory selection based on your part, budget, and quality requirements
- Dedicated sourcing and engineering support throughout the project
- Independent quality inspections before shipment
- Regular production monitoring and progress reporting

What is the difference between Type II and Type III hardcoat anodizing?
Type II anodizing uses a sulfuric acid process to build a moderate oxide layer suited to corrosion resistance, color, and general cosmetic finish. Type III, known as hardcoat anodizing, builds a thicker, denser coating that adds wear resistance and surface hardness, making it the choice for functional parts like pistons, valves, and sliding or wear-bearing components. AASA can recommend which type fits your application based on function and appearance requirements.
Can AASA match a specific anodized color?
Yes. Color anodizing uses a dye immersion step after the anodic coating forms, and factories in AASA's network can match standard colors or work from a physical sample or color reference to get close to a custom shade. Because dye uptake varies slightly by aluminum alloy, we recommend a sample approval step before full production.
Does anodizing add dimensional thickness to a part?
Yes. Anodizing grows the oxide layer partly into and partly out of the original surface, so it does add measurable thickness, typically a few microns for Type II and up to 25 to 50 microns or more for Type III hardcoat. For parts with tight tolerances or press-fit features, this growth should be accounted for in the drawing before anodizing.
Can AASA anodize parts with tight tolerances or threaded features?
Yes. AASA's factory partners can mask threads, bores, and other critical features to keep them free of coating buildup, and can plan for anodizing growth on toleranced dimensions. Sharing your drawing with called-out critical features lets us confirm the right masking and process approach before production.
Which aluminum alloys anodize best?
6063 and 6061 generally anodize with a clear, consistent cosmetic finish and are common choices for architectural and appearance parts. 5052 and 7075 anodize well for structural and hardcoat applications. 2024 and other copper-bearing alloys anodize with a yellow or gray tint and are typically chosen for function over cosmetic appearance. AASA can advise on alloy selection based on your finish requirements.
Which countries does AASA source anodizing from?
AASA's anodizing network spans India, China, Vietnam, and Thailand. Country selection depends on your alloy, coating type, color requirements, production volume, and target landed cost.
What information do you need to quote anodizing?
We typically need a drawing or technical specification, aluminum alloy, anodizing type (Type II or Type III), color or finish requirements, coating thickness spec if applicable, estimated order quantities, and your desired timeline. If you don't have complete documentation yet, our team can still discuss your requirements and help determine what's needed to move the project forward.
