What is Iridite finish?
Iridite is a N.C.P. (non-chrome chemical process) that produces a protective chromate conversion film coating on aluminium and its alloys. The process is RoHS and WEEE compliant. It is often used as a protective coating for abraded anodized surfaces and to provide an electrical contact. …
What is the difference between Iridite and alodine?
A. Iridite is a trade name for a whole family of chromate conversion coatings. Alodine 1200S is the trade name for aluminum chromate that meets MIL-C-5541. Iridite 14-2 is the particular trade name for a product that is chromate conversion for aluminum.
What is alodine finish?
Alodine finish is a chemical conversion coating used for metals, particularly aluminum, to improve its resistance to rust and corrosion.
What is clear chromate?
Clear chromate is a chemical conversion coating that is applied over zinc plating during the surface coating process. It protects the substrate and corrodes before the base metal, unlike most other commonly plated metals. Clear chromate films are typically very thin, around .
What is gold Iridite?
Commonly known as Yellow and Clear Iridite or Alodine finishes, chemical conversion coatings are used primarily for paint adhesion on aluminum. Although the iridescent gold finish is very attractive, it is not as durable as an anodized finish. Two classes of coatings are available under Mil-C-5541 and Mil-C-81706.
Is Iridite coating conductive?
These are conductive of electricity and therefore useful in applications in electronic industries where the component needs to retain its electrical conductivity but also be protected against corrosion. In addition this conductivity means it is an excellent pre-treatment for painting and powder coating processes.
What is Iridite NCP?
Iridite NCP is an innovative new process that offers extremely high resistance to corrosion, tested to 1000 hours on many aluminium alloys. For new chrome free technology that meets all environmental standards, bare corrosion resistance without painting, even after heating or baking.
Is alodine 1200 conductive?
Alodine 1200S conforms to MIL-C-5541E Class 1A and 3 coatings, Methods A, B & C application. Alodine coatings are electrically conductive.
What is gold alodine?
Awlgrip Alodine 1201 Is A Chrome Conversion Coating for Aluminum. It Is A Non-flammable, Chromic Acid Based, Coating Chemical That Will Produce A Chrome Conversion Coating on Aluminum And Its Alloys. This Coating Is Gold to Tan In Color And It Becomes A Part of The Aluminum Surface.
When should alodine be used?
Alodine is actually a brand. It is an international brand of various materials from Henkel Technologies for use in conversion, anodizing and functional coatings that are suitable for use on aluminum, magnesium and other non-ferrous materials for corrosion protection and paint adhesion.
Is Iridite conductive?

What is Iridite finish on aluminum?
Chromate (Iridite) on Aluminum. Commonly known as Yellow and Clear Iridite or Alodine finishes, chemical conversion coatings are used primarily for paint adhesion on aluminum. Although the iridescent gold finish is very attractive, it is not as durable as an anodized finish. Two classes of coatings are available under Mil-C-5541 and Mil-C-81706.
What is Iridite chemical film?
Mil-C-5541F, Chemical Films, Chromate ” Iridite “, (Aluminum) Chemical Film coatings are gelatinous films which provide some sort of a barrier medium to retard corrosion on aluminum surfaces and enhance adhesion of subsequent coatings such as paints and primers.
What is the color of Iridite?
Color can vary from colorless to golden – iridescent – brown. Materials conform to Mil-C-81706. Coatings shall be continuous free from powdery areas, breaks, scratches, etc. Sometimes called yellow iridite No dimensional change are effected with Iridite finishes.
Is iridescent gold more durable than anodized gold?
Although the iridescent gold finish is very attractive, it is not as durable as an anodized finish. Two classes of coatings are available under Mil-C-5541 and Mil-C-81706. Both classes provide a minimum of 168 hours of salt spray protection. In March of 2006 CTI completed the installation of a high capacity Iridite coating line.
