Aluminum Anodizing

Aluminum Anodizing

Aluminum anodizing is a controlled electro-oxidation process that transforms the metal's natural oxide into a dense hard layer of 6 to 25 µm, offering corrosion resistance, wear durability and bright color options without adding weight. After laser or router cutting, parts are mounted on racks in an acidic electrolyte bath where electric current grows hexagonal oxide cells whose pores readily accept dye. We offer five standard colors — clear, black, red, blue and gold — each sealed in boiling deionized water to fix pigments and meet MIL-A-8625F corrosion requirements. The treatment slightly increases dimensions (≈ 0.0005" growth per face), maintains electrical insulation and provides excellent adhesion for paint or adhesives. As each part must be cleaned, racked, anodized, dyed, sealed then dried, anodizing adds approximately 10 business days to overall lead time.

Standard colors: clear, black, red, blue and gold. Ideal for enhancing corrosion resistance and visual appearance of aluminum parts.

What is it for?

Unlike paint, which sits on top of the surface, anodizing becomes an integral part of the aluminum: the oxide layer is grown from the metal itself, so it won't chip or peel. It's the treatment of choice when a part has to keep its look and corrosion resistance for years, indoors or outdoors.

The process only applies to aluminum alloys. At Laseo, you can combine it with cutting and bending of 3003 aluminum, 5052 aluminum, 6061 aluminum, as well as aluminum checker plate. Other metals (steels, stainless) are better suited to powder coating.

Why choose it

• Protection without added weight: the hardened layer protects against corrosion and wear without adding any appreciable weight — a plus for moving or transported parts.
• Long-lasting looks: clear, black, red, blue and gold colors, dyed into the body of the oxide for a finish that resists scratches far better than paint.
• Electrical insulation: the anodized surface is non-conductive, handy for enclosures and electronics mounts.
• Good adhesion: an excellent primer for paint or adhesive applied afterward.

Typical use cases

Nameplates and device faceplates, panels and brackets exposed to Canadian winters, electronics enclosures, decorative hardware, components for outdoor, transport and light machinery equipment — anywhere aluminum needs to stay clean and protected for the long haul.
