Aluminum Anodizing
for Custom Metal Parts
We provide Standard Type II and Hard Type III anodizing for custom aluminum parts, supporting corrosion protection, wear resistance, appearance and functional requirements.
Surface Protection and Appearance for Aluminum Parts
Anodizing creates a controlled oxide layer on the surface of aluminum parts, helping improve corrosion resistance, wear performance and surface appearance.
We support anodizing for custom aluminum components according to part geometry, application requirements and the specified finish.
Corrosion Protection
Anodized surfaces can provide improved protection against oxidation and environmental exposure.
Wear Performance
The anodized layer can improve surface durability for functional and repeatedly handled components.
Color & Appearance
Clear, black and selected dyed finishes can support both functional and appearance-sensitive applications.
Custom Part Requirements
Finish selection can be coordinated with drawings, masking, critical surfaces and dimensional requirements.
Choose the Right Anodizing Process for Your Aluminum Parts
Standard Type II and Hard Type III anodizing serve different appearance, protection and performance requirements. Select the process that best matches your application.
Standard Anodizing (Type II)
A versatile anodizing option for corrosion protection, appearance and color finishing on general-purpose aluminum components.
Hard Anodizing (Type III)
A harder anodized surface for improved wear resistance and functional performance in demanding industrial applications.
Color and Surface Appearance for Anodized Aluminum
Anodized aluminum can be specified with natural, black or selected dyed finishes according to the application and appearance requirements.
Final appearance is also influenced by the aluminum alloy, surface preparation and selected anodizing process.
Natural / Clear
A clean metallic appearance for aluminum parts where corrosion protection and a neutral finish are preferred.
Black Anodizing
A widely used dark finish for industrial, electronic and appearance-sensitive aluminum components.
Dyed Color Options
Selected colors can be used for identification, product appearance and branded component applications.
Surface Texture
Machined, polished or blasted surfaces can create different visual textures before the anodizing process.
For appearance-sensitive projects, share your target color, finish reference or physical sample during project review.
From Machined Aluminum Part to Final Anodized Finish
We can coordinate aluminum part manufacturing and anodizing within one sourcing workflow, helping maintain drawing, finish and inspection requirements throughout production.
Part Manufacturing
Aluminum parts are machined according to your drawings, tolerances and surface finish requirements before anodizing.
Preparation & Masking
Before anodizing, critical areas such as threads, sealing surfaces or selected contact points can be masked when an anodize-free surface or tighter dimensional control is required.
Anodizing & Inspection
After anodizing, finished parts are checked for color, appearance and key project requirements. Masked threaded holes or protected areas remain untreated as specified.
Key Details to Review Before Anodizing
Anodizing results depend on the aluminum alloy, part geometry, surface condition and functional requirements. Reviewing these details before production helps reduce avoidable variation and protects critical features.
Aluminum Alloy
Different aluminum alloys can respond differently to anodizing and may produce variations in color, appearance and surface finish.
Critical Dimensions
Close-tolerance fits, bores and mating features should be identified before processing because anodizing can affect finished dimensions.
Threads & Masking
Threads, sealing surfaces and other areas that require special treatment or masking should be clearly marked on the drawing.
Color & Appearance
Target color, gloss level and cosmetic expectations should be confirmed with drawings, reference samples or approved finish standards.
Contact & Rack Areas
Electrical contact points are required during anodizing, so acceptable rack or contact locations should be considered for visible surfaces.
Inspection Requirements
Appearance, dimensional checks and other acceptance requirements can be defined according to the function and visibility of the part.
Typical Aluminum Parts for Anodizing
Anodizing is widely used for machined and fabricated aluminum components that require corrosion protection, controlled appearance or improved surface performance.
Machined Housings
CNC-machined aluminum housings and bodies for functional assemblies and equipment.
Brackets & Mounts
Structural brackets, mounting components and support parts requiring durable finished surfaces.
Enclosures & Panels
Aluminum enclosures, covers and panels where appearance and corrosion resistance are both important.
Handles & Controls
Handles, knobs and control components requiring consistent color and a finished appearance.
Heat Sinks & Profiles
Extruded or machined aluminum profiles and heat-sink components with functional surface requirements.
Precision Functional Parts
Custom aluminum components with defined dimensional, masking, cosmetic or wear-related requirements.
