Color Tint of Chromate Conversion Coating

Material: die-cast aluminum and possibly magnesium Is it possible to apply a tint to the chromate conversion process to get reliable colors similar to the common bright colors available in the anodizing process? Anodizing cannot be used due to the need for electrical conductivity. Either bright blue or bright yellow/gold is being sought to look like an anodized part. This will be needed for batch processing of a production part rather than on a sample basis so consistent appearance quality is required.

Michael,

Clariant Corporation in Charlotte NC sells dyes for the chromate conversion process, however whether or not your parts will look as if they have been anodized, my guess is no. Castings for the most part do not accept dyes very well, but the only way be sure is to try it.

Good Luck
