A fluorine resin coated aluminum material which is prepared by a process comprising the steps of coating a fluorine resin on an aluminum material having a magnesium content of from 0.01 to 10.0 wt %, and sintering the coated resin at a temperature not lower than the decomposition point of said fluorine resin.

Aluminum material coated with fluorine resin

A process and apparatus for electrolytic etching of aluminum or its alloy is disclosed wherein an electric current is passed between an anode and a cathode which are spaced opposed in an electrolytic bath with a workpiece removably supported on an insulating frame so that the side of the workpiece to be etched faces the cathode, the insulating frame being disposed between the anode and the cathode and having at least one opening formed therein.
