Alodine Conversion (Chromate, Iridite)

Ensure that your parts can withstand the elements, no matter the environment.

Chromate Conversion, also known as Alodine and Iridite, provides corrosion resistance for aluminum parts. Through passivation, or chemically altering the surface properties of a part, this process helps to prevent oxidation in the field. Zinc, cadmium, copper, silver, magnesium, and tin alloys benefit from chromating as well. It can also be used to greatly enhance phosphate coatings and prevent “white rust”. Another advantage of this process is that it adds adhesion for priming and paint, on the otherwise unpaintable surface of aluminum. In some cases, it can substitute for primer – and the chromate coat can even be left unpainted because of its self-healing properties. Parts that undergo this conversion can remain electrically conductive, although the process itself does not add or enhance conductivity.

Typical and proven applications of CCC:

• Any part or casting made of aluminum, magnesium, or the other materials listed above; or having received zinc plating or other phosphate coatings.

Our chromate conversion coat process offers the following advantages:

• Prevents oxide formation
• Prevents corrosion
• Provides adhesion for organic coating (paint, primer, etc.)
• Microscopically thin
• Flexible and resilient (self-healing)
• Coats in recesses
• Provides color

Depending on your needs, parts may be treated with a yellow/gold or clear coating. Both offer superior protection at a minimal cost to you. Guarantee your product over a much longer period of time when protected by our coatings.

Our process exceeds major industry standards, including MIL-C-5541C, MIL-DTL-5541F and MIL-C-81706. Any special information pertaining to your needs will be furnished upon request.
