I was doing layout work on the surface plate on a 3 1/2 X 6 1/4 X 11 1/4" 7075 block, not thinking about the aluminum streaks on the granite plate until too late. I know drain cleaners (sodium hydroxide) mixed with in a strong solution will make the bright smears to disappear but I'm concerned about the granite of the plate.
A: Aluminum oxide offers versatility and durability, making it suitable for a wide range of materials and sanding tasks, while silicon carbide provides sharper and harder abrasive properties, ideal for tackling rough sanding on more complex materials and achieving a finer finish on surfaces with high tensile strength.
When sanding aluminum-oxide finishes, the same concept applies. Rather than start with the most aggressive grit you can find (the large mallet), start with something finer, like an 80 grit (the ice pick). The finer belt will break up the finish, and after that, you can move to the rougher grit to get the floor flat and take it from there.
Aluminum Oxide Grit — Sharp, hard, and durable, it prepares surfaces for coating. It also frosts glass. Silicon Carbide Grit — Quickly cleans granite, ceramics, silicon, quartz, cemented carbides, and other tough materials.
