Abstract: A fluorine resin coated aluminum structure comprising:(a) an aluminum substrate with a roughened surface;(b) a coating of aluminum oxide formed on the surface of the aluminum substrate; and(c) a baked coating of a fluorine resin firmly bonded to the aluminum oxide coating, the fluorine resin coating having a thickness of about 5 to about 100 microns and a surface roughness represented by an R.sub.max value of about 5 to about 60 (.mu.) and an R.sub.z value of about 4 to about 50 (.mu.). This aluminum structure is especially useful as a material for cookware because of its superior anti-stick and low friction characteristics and the good adhesion of the resin coating to the substrate.
