I think this is similar to the clear anodic coating with caustic etch, matte finish as pre-treatment. Dissolved aluminum in the caustic solution renders a satin finish to the parts.

The definition "Satin finish" is used for "matte finish" generally. You have to remove 100-120 gr. aluminium per sq.m to obtain this finish on aluminium, in an etching solution of caustic soda [affil links] (free NaOH as 60-120 g/l and preferably with a proprietary additives for homogeneous appearance, at 60-65 deg.C for 10-20 minutes depending on the concentration of the solution.
