Clear (Trivalent) Alodine, 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 – chemically altering the surface properties of a part – this process helps to prevent metal oxidation in the field. Chemical film is another name for this metal finishing process.
Another advantage of chromate conversion is that it provides adhesion for priming and painting 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 Alodine and chromate conversion coating:
- Any part or casting made of aluminum or magnesium;
- Any part or casting made of zinc, cadmium, copper, silver, tin alloys, or having received zinc plating;
- It can also be used to greatly enhance phosphate coatings and prevent white rust.
Our chromate conversion coating process offers the following advantages:
- Prevents oxide formation
- Prevents corrosion
- Provides adhesion for organic coating (paint, primer, etc.)
- Prepares the part for powder coating
- Microscopically thin
- Flexible and resilient (self-healing)
- Coats in recesses
- Provides color
Depending on your needs, parts may be treated differently by taking into consideration whether the part will be painted or unpainted. Guarantee your product over a much longer period of time when protected by our coatings.
Our Alodine process is now fully RoHS compliant, and exceeds major industry standards, including MIL-C-5541C, MIL-DTL-5541F as well as MIL-C-81706 and MIL-DTL-81706A. Any special information pertaining to your needs will be furnished upon request.
