CHROMATE CONVERSION / IRIDITE
Chromate conversion is a thin film coating applied on aluminum components that offers excellent corrosion resistance and is a great primer for painting applications. Chromate conversion is also frequently referred to as chem film and yellow Iridite, as well as the brand names Iridite and Alodine.
Promotes paint adhesion
Offered in hexavalent chrome and RoHS compliant chemistries
The most common finish is clear and yellow
Used as a corrosion preventative film for electrical applications where low resistant contacts are required
When applied, very little to no dimensional change
Most commonly used in aerospace and military/defense industries
Chromate Conversion, Mil-DTL-5541 Specified, Protected Aluminum
The excellent strength and relatively lightweight of aluminum means it is a popular choice for a wide variety of components in the transport, aerospace, medical, telecommunications, military, and related industries. Unfortunately, aluminum surfaces that are exposed to moisture can degrade, leading to reduced performance and potential part failure. To reduce the risk of this happening, many manufacturers choose to apply chromate plating to their aluminum parts. As an established chromate conversion provider that meets Mil-DTL-5541 standards, Co-operative Plating is prepared to undertake this process for you.
The Mil-DTL-5541 specification was specifically created to provide standards to ensure that military defense weapons, if aluminum or made with an aluminum alloy, were coated for maximum corrosion resistance and provided a surface with better paint adhesion than uncoated aluminum. For military clients and related partner industries, our aluminum chromate conversion coatings meet the requirements of MIL-DTL-5541 and the two classes of the chemical conversion coating. The chromate process provides a clear iridescent finish, sometimes slightly golden, and low electrical resistance.
Aluminum Conversion Coating Can Enhance Part Life and Performance
Not only does a conversion coating have an immediate protective effect on your aluminum parts, but it also has a number of other benefits. A suitable aluminum conversion coating provides an excellent primer, meaning that subsequent plate or paint will adhere firmly and evenly. Conversion coating offers low resistance and is extremely thin, meaning that the dimensions of the part remain virtually unchanged.
