Re: Copper plate aluminum heads

[green-thumbs]

There is a treatment called anodizing in which aluminum can be given various color treatments that seem to hold up very well. The object to be treated is made the anode
and the type of salt in the electrolyte determines the color. Along the same line as electroplating but a different process. Copper is above aluminum on electrochemical
scale so in a corrosive environment the aluminum would be sacrificed. That is not to
say it can not or is not done.
