I assume it to be annodised Al.
Possible, but I've never heard it termed that.
And whilst anodizing might prevent galvanic corrosion and has a pretty good bond with the Al, it is a notoriously difficult surface to get a good bond to.
When Lotus were researching the gluing&pining together of the Aluminium substructure for the Elise
, they had to use a 180C heat-set epoxy and thoroughly clean the bond faces.
