I've been surface finishing some 6061 aluminum bar stock making a chassis. These 3M sanding disks with a small spritz of Alumicut are working great and last long. In fact the finish is better as the abrasive clogs, smoother.

I thought I'd have to go to finer grits, but I can start and stop at 320! After sanding I'll burnish the outsides to get a typical "brushed finish" aluminum. These are really great sanding disks for aluminum. One tip, keep the orbital sander moving in circles across the piece, not moving longitudinally. This pattern gives a satin finish with no patterns created. I'm using a 5 inch Dewalt cordless random orbital sander.
