Precision Color Anodizing
Enhance both form and function with Diamond Metal Finishing’s precision color anodizing—MIL‑A‑8625 Type II dyed finishes in black, red, green, orange, gold, and more. Delivering vibrant, corrosion-resistant coatings with consistent color depth, minimal dimensional change.
Color Anodizing (Various Colors via Dyeing)
At Diamond Metal Finishing, our color anodizing services combine engineering-grade durability with striking visual aesthetics. Using MIL‑A‑8625 Type II Class 2 sulfuric acid anodizing, we deliver a medium-thickness aluminum oxide layer that readily absorbs dyes—resulting in vibrant, long-lasting finishes on precision aluminum components.
Our dyeing process is controlled to ensure uniform coloration across batches, even on complex geometries and tight-tolerance parts. Whether you need high-contrast black for laser marking, color-coded components for assembly, or decorative hues for branding, DMF’s in-house anodizing and dyeing line meets the demand.
Backed by ISO 9001:2015 certification and full MIL‑A‑8625 compliance, our color anodizing enhances corrosion resistance, wear durability, and thermal stability—all while allowing you to distinguish parts with vivid, professional-grade finishes.

Frequently Asked Questions
What is color anodizing?
Color anodizing is a Type II anodizing process where aluminum parts are dyed after oxide film formation—resulting in vibrant, corrosion-resistant finishes.
Which colors do you offer?
We offer black, red, green, orange, gold, and clear finishes. Custom colors may be available depending on volume and feasibility.
Will the colors fade over time?
Our sealed anodized finishes are UV- and corrosion-resistant, offering stable performance in most environments.
Can I get multiple colors in one order?
Yes, depending on part quantities and production batch scheduling. Contact us to discuss your requirements.
What part types are suitable for color anodizing?
Any aluminum part made from a compatible alloy, such as 6061, 2024, or 7075, can be color anodized—especially enclosures, housings, brackets, and trim components.
Do you offer masking for selective coloring?
Yes. We can mask specific areas such as threads or electrical contact zones—just indicate them in your technical drawing.
Do you offer post‑anodize sealing and PTFE impregnation?
We provide hot‑water, nickel‑fluoride, or polymer seals to lock in corrosion resistance and color fastness. PTFE infusion is also available for low‑friction or non‑stick requirements.
Is color anodizing RoHS compliant?
Yes, our dyeing and anodizing processes use RoHS-compliant materials.
What are your typical lead times?
Standard turnaround for Type II runs is 3–5 business days, depending on part volume, masking complexity, and color requirements. Expedited service is available on request.
