Type of aluminum alloy for anodizing cathodes

We do sulfuric acid anodizing of aluminum. We are presently using aluminum anodes in our tanks and aluminum clamps to hold our sheet stock. What is the best aluminum alloy to use for this application. We use hydrofluoric acid for our sheet and rack strip. We are presently using 6061 alloy.
