Long-Life Grinding Wheels forAngle Grinders— Use on Metals. Wheels are a blend of aluminum oxide and zirconia alumina, which removes more material and lasts three times as long as our General Purpose Grinding Wheels. They are also known as Type 27 wheels, raised-hub wheels, and grinding discs.
The first consideration is the material to be ground. This determines the kind of abrasive you will need in the wheel. For example, aluminum oxide or zirconia alumina should be used for grinding steels and steel alloys. For grinding cast iron, non-ferrous metals and non-metallic materials, select a silicon carbide abrasive.

Grinding aluminum will only clog up your stone grinding wheel. It is the next person inline who is going to grind either steel or iron. Aluminum mixed with iron or steel particles is actually very dangerous. If you have finished grinding your aluminum piece and forget to clean the stone grinding wheel then you are creating a potential fire hazard.

Fortunately, because aluminum is a soft metal, it doesn't cause sparks during grinding, and is actually more prone to melting or breaking away from the main material in small portions. Contrastingly, hard metals are much more prone to sparking during the grinding process, which makes grinding hard metals such as titanium incredibly dangerous.

High quality, aluminum-specific products are designed to cut smoothly while minimizing burr formation. They also significantly reduce the noise and vibration through the cut, and are therefore easier to control. Wheels are available for cutting or grinding only, or as combination cutting/grinding wheels.
It is not cost effective to grind aluminum, even skim passes, as it clogs the wheel so much and so fast that it does not "cut". Going to a larger grit size and a very frangible resin will allow it to cut better, but you will go thru wheels very fast. My thought is that you found it in a hand grinder with a 1/4" thick cutoff wheel.
Dust in particular, such as that caused by aluminum grinding, can be inhaled and cause damage to internal organs at a nearly microscopic level. Fire/Explosion Risks: The aforementioned dust can create an explosion risk given the right conditions, such as when it is exposed to flames or sparks. These conditions can cause small fires at the best ...
