Issues come up when people use the same grinder for different materials - especially aluminum. Aluminum will embed in the grinding wheel, and once it heats up, can cause the wheel to explode.

I'm a welder and I have never heard that before in my life. I've used a disk covered in alum. to grind steel lots of time, no blown up disks. Unless you have personally seen it happen, I think whoever told you that is full of shit lol.
On that note though...wierder things have happened, pure oxygen and oil has been known to explode.
