Standard Anodizing (Type II) for Custom Aluminum Parts
We provide Type II anodizing for custom aluminum parts requiring corrosion protection, controlled appearance and a wide range of color options for functional and cosmetic applications.
What Standard Type II Anodizing Provides
Type II anodizing forms a controlled oxide layer on aluminum, providing corrosion protection while supporting natural, black and selected dyed finishes for functional and cosmetic parts.
It is commonly used when a project requires a practical balance of surface protection, appearance, color options and dimensional control without the heavier build associated with hard anodizing.
Corrosion Protection
The anodic oxide layer improves protection of aluminum surfaces against environmental exposure and everyday service conditions.
Color & Appearance
Type II supports natural, black and selected dyed finishes for projects where both appearance and surface protection are important.
Improved Surface Durability
The anodized surface provides better wear and handling resistance than untreated aluminum for many general-purpose applications.
Functional & Cosmetic Parts
Suitable for machined housings, brackets, enclosures, controls and other aluminum components with defined finish requirements.
Type II Anodizing for Natural, Black and Dyed Finishes
Type II anodizing can provide natural, black and selected dyed finishes for aluminum parts where corrosion protection and controlled appearance are required.
Final color can vary with aluminum alloy, machining condition, surface preparation and finishing requirements.
Review Critical Features Before Type II Anodizing
Type II anodizing changes the finished aluminum surface, so critical dimensions, threads, mating features and cosmetic areas should be identified before production.
Drawings that clearly define functional surfaces and finish requirements help us select appropriate preparation, masking and inspection methods.
Critical Dimensions
Close-tolerance diameters, bores, fits and mating surfaces should be identified so the anodized condition can be considered during manufacturing and inspection.
Threads & Bores
Internal threads, threaded holes and precision bores can be reviewed for masking or other process controls when anodic coating is not required on those features.
Cosmetic Surfaces
Visible surfaces should be identified on the drawing when appearance, color consistency or allowable contact marks are important.
Rack & Contact Areas
Electrical contact is required during anodizing, so acceptable rack or contact locations should be considered for parts with controlled cosmetic surfaces.
Alloy & Surface Condition
Aluminum grade, machining marks and surface preparation can influence final color and appearance and should be considered before finishing.
Drawing Requirements
Finish type, color, masked areas, cosmetic surfaces and critical inspection requirements should be noted whenever they affect part function or acceptance.
Typical Aluminum Parts
Finished with Type II Anodizing
Type II anodizing is widely used on custom aluminum parts where corrosion protection, appearance control and a practical finished surface are required.
It is commonly applied to CNC machined housings, brackets, covers, fittings and other aluminum components that benefit from both functional protection and a clean finished appearance.
Machined Housings
Aluminum housings and blocks often use Type II anodizing to improve corrosion resistance and surface durability.
Brackets & Mounts
Structural and support components can use anodizing for a controlled finish and better service performance.
Precision Components
Functional machined parts can be anodized when appearance, dimensional coordination and surface protection are all important.
Type II Anodizing vs Type III Hard Anodizing
Type II and Type III anodizing both create an anodic oxide layer on aluminum, but they are generally selected for different performance priorities.
Type II is commonly used where corrosion protection, appearance and color options are important, while Type III hard anodizing is more focused on wear resistance and demanding functional surfaces.
Type II Anodizing
Type III Hard Anodizing
Which Anodizing Type Should You Choose?
Choose Type II when appearance, corrosion protection and color flexibility are the main priorities. Consider Type III when the part requires greater emphasis on wear resistance and functional surface performance.
