Small Parts Anodizing
At Diamond Metal Finishing, our Small Parts Anodizing service is engineered to deliver precise, durable oxide coatings on miniature aluminum components without compromising dimensional accuracy or performance. Whether you’re anodizing electrical connectors, micro fasteners, valve stems, or detailed medical housings, DMF ensures uniform coating thickness and repeatable quality—down to the smallest parts.
Our MIL‑A‑8625 Type II anodizing line is optimized for tight-tolerance parts with intricate geometries, offering both Class 1 (clear) and Class 2 (dyed) options. Using controlled chemistry, current density, and temperature regulation, we achieve high-purity aluminum oxide films from 5 to 25 µm (0.0002″–0.001″) with minimal dimensional growth.
DMF’s process supports full masking, racking, and PTFE infusion for high-wear, high-precision components. Backed by ISO 9001:2015 certification and batch traceability, our anodizing for small parts meets the needs of industries where performance, aesthetics, and consistency are non-negotiable.

Frequently Asked Questions
What is small parts anodizing?
It’s the anodizing of miniature or tight-tolerance aluminum components using custom racking and low current densities to ensure uniform coatings.
Can you mask threads or contact points?
Yes. We offer precision masking for threads, mating surfaces, and contact zones to maintain fit and function.
What colors are available for small parts anodizing?
We offer standard colors like Black, Clear, Red, Green, Orange, and Gold. Custom colors may be available for volume orders. Some vibrant hues may appear slightly muted on small parts due to surface area and alloy type.
What dimensional changes should I expect?
Typical growth is 0.0001″ to 0.0005″ per side depending on thickness and alloy. Always confirm with our team for your specific part.
What’s the turnaround time for small parts anodizing?
Standard lead time is 3–5 business days. Rush services available depending on volume and part specs.
Do you offer PTFE coating or sealing?
Yes. We offer hot-water, nickel-acetate, or polymer sealing, plus optional PTFE infusion for high-wear applications.
Do you offer PTFE coating or sealing?
Yes. We offer hot-water, nickel-acetate, or polymer sealing, plus optional PTFE infusion for high-wear applications.
Which aluminum alloys are best for small parts anodizing?
Commonly anodized alloys include 6061, 6063, 7075, 2024, and 5052. These alloys support consistent oxide layer growth and high-quality dyed finishes. Some cast aluminum alloys may yield less uniform results due to their silicon content.
Can I specify which areas to leave uncoated?
Yes. We offer precision masking and plugging for threads, bores, contact pads, and mating surfaces. Please specify on your technical drawings for accurate masking during setup.
What is the typical coating thickness for small components?
Coating thickness generally ranges from 5–25 µm (0.0002″–0.001″), depending on the part geometry, alloy, and desired finish. We help you select the optimal thickness based on performance and tolerance requirements.
Do you offer hardcoat (Type III) anodizing for small parts?
For high-wear applications, we can recommend Type III anodizing on select alloys and part geometries. However, due to higher film thickness, this may not be suitable for extremely tight-tolerance or delicate parts.
What sealing options are available for small parts?
We offer hot-water, nickel-acetate, and polymer sealing, depending on corrosion resistance, dye retention, and end-use requirements.
Can anodized small parts be laser marked?
Yes. Black and clear anodized parts offer excellent contrast for laser etching. Colored finishes may also be laser marked with reduced contrast.
Can I combine small parts anodizing with other finishing services?
Absolutely. We offer laser engraving, digital printing, screen printing, and PTFE infusion—all under one roof for a streamlined production workflow.
How soon can I get my anodized parts back?
Our standard turnaround is 3–5 business days, depending on volume and part complexity. Rush services are available upon request.
