In general, the abrasive used to make most homeshop type grinding wheels is for grinding steel (aluminum oxide) Don't let the name fool you, aluminum will clog the bejabers out of your wheel and you will have a mess trying to get your parts smooth. Contact any good industrial supply company in your area and request info.on silicone carbide wheels for grinding aluminum. Their grinding wheel people will advise you on grit size and wheel hardness for your intended use. The same applies to disc and belt sanders. Look up Norton in your industrial directory, they are one of the worlds best for grinding and polishing supplies. Doug Bell Sr.

Don't forget to wear a mask when using silicone carbide wheels. It is not good for the lungs. It gets in the air much worse than aluminum oxide wheels do. The reason it cuts so good is it breaks down fast and doesn't load up. All that silicone carbide that is breaking down goes in the air. This is assuming you are talking about the common green colored silicone carbide wheels that I use to sharpen carbide cutters.
