Can you anodize zinc?

We are producing a part which is an aluminum extrusion, Alloy #6005-T5. We want to change to a Zinc, or Zinc aluminum casting. What type of plating can we now use to replace the gold anodizing we were doing?

Although zinc can be anodized it is not really a commercial process and it's not for decorative effect. Yellow chromated on zinc will look reasonably like gold anodizing but certainly not a good color match. If you don't need conductivity, maybe electrophoretic lacquering would give you the appearance you want.
