Resolve 8 Finish Risks Before Processing
Use these anodizing design guidelines to define the interfaces your assembly depends on.
Define the Finished Size Before Machining

| Your drawing | Before-treatment and final dimensions with datums. |
|---|---|
| Our review | Specified thickness, outward growth and measurement plan. |
Keep Your Threads and Bores Functional
State thread and bore acceptance in the finished condition. Anodizing masking, allowance or an approved secondary operation may be needed.
| Your input | Thread callout, gauge and critical bore limits. |
|---|---|
| Our review | Masking feasibility and final fit checks. |
Draw the Areas That Must Stay Untreated
Identify grounding, bonding and other conductive interfaces explicitly. Define mask boundaries and final contact requirements.
| Your input | Contact areas and clear boundary dimensions. |
|---|---|
| Our review | Masking method, transitions and inspection access. |

Check Your Clearance After Finishing
A shaft, slot or sliding interface must work after the finish is complete. Review both mating components and their treatment states.
| Your input | Counterpart, clearance and service environment. |
|---|---|
| Our review | Finished mating state and usable gauges. |
Review Access, Edges and Trapped Solution

Anodizing surface finish starts with the substrate. Define machining marks, brushing direction or blast texture before approving a sample.
| Your input | Original surface and desired texture. |
|---|---|
| Our review | Pretreatment, appearance sample and handling. |
Choose Your Alloy and Finish as One System
Material names and color names alone do not define an acceptable finished part.
6061 Aluminum
For anodizing 6061 aluminum, identify temper, machining state, cosmetic faces and final dimensions.
6063 Aluminum
For anodizing 6063 aluminum, review extrusion surface, handling marks and the intended appearance.
7075 Aluminum
For anodizing 7075 aluminum, confirm grade, condition and the complete finish specification.
Clear, Black & Color
Clear anodizing is undyed anodic oxide, not clear paint. Black anodizing and other colors require agreed samples.
Brushed or Blasted

Welded & Cast Parts
Review filler metal, weld zones and casting alloy separately; appearance may differ from wrought stock.
Type II anodizing is commonly used for protective and decorative finishes; Type III anodizing is a hardcoat route for specified wear-focused requirements. Thickness, sealing and supplier capability require project review. No certification or universal performance is implied.
Plan Your Finish, Samples and Repeat Orders
Compare the same delivered condition rather than a color-only price.
Finish Review
Agree alloy, callout, masks and critical fit.
Treated Sample
Review actual color, texture and final dimensions.
Repeat Release

Answers Before Your First Order
What is anodizing?
Anodizing is an electrochemical conversion of the aluminum surface into an anodic oxide layer. It differs from paint and deposited metal plating. Choose the finish around the exact alloy, service environment, appearance and final fit.
Type II vs Type III anodizing: which fits your part?
Type II is commonly considered for protective and decorative finishes; Type III is a hardcoat route for wear-focused requirements. Specify thickness, sealing, appearance and tests. Actual availability and compliance with your complete specification must be confirmed before ordering.
Does anodizing change dimensions or affect threads?
Yes. Surface conversion and outward growth affect mating dimensions. Define finished limits, required thickness and measurement method. Review machining allowance and masking separately for tight bores, threads and locating faces; do not apply one universal growth ratio.
Can anodizing be color matched and selectively masked?
Agree the alloy, pretreatment, texture and a representative physical color sample, including permitted variation and viewing conditions. Draw mask boundaries for contacts, threads and critical fits; confirm feasible methods and allowable rack marks.
How much does anodizing cost, and what is the minimum order?
Cost depends on part size, alloy, incoming surface, finish type, quantity, racking, masking, sample work and inspection. Small batch anodizing can carry a minimum processing charge. Request your actual trial and production quantities; no universal minimum is stated here.
How long does anodizing take?
Confirm separate milestones for preparation, sample approval, processing, inspection and delivery. Material condition, required masks, special tests, batch scheduling and any machining affect the actual quotation schedule.
Anodizing vs powder coating or plating: how do you choose?
Compare substrate, exposure, appearance, electrical requirements, wear and finished fit. Anodizing converts the aluminum surface; powder coating applies a polymer coating; plating deposits another material. Review the complete finishing system rather than treating these routes as interchangeable.
Can anodized aluminum be machined, and what should your drawing specify?
Machining after anodizing removes the finish locally. Agree whether exposed areas are acceptable or need further treatment. Your drawing should identify alloy/condition, finish specification and revision, thickness, color, seal, masks, rack-contact zones, final dimensions and acceptance records.
