Hard anodizing with Mg and Si present

What is the affect of Magnesium at .4-.6 % levels combined with Silicon 9.5-11.5 on the hard anodizing process? Can it be done? How is surface finish affected?

It is a very poor candidate for hard anodizing. It can be run thru the process, but the outcome will be unacceptable to many end users.

High alloy die-castings can be hard anodized. The coating is not as hard nor as uniform in appearance and thickness as hardcoat on wrought alloys. All hard anodizing will result in an increase in surface roughness.
