A lot of Percussion equipment is made with aluminum. DW makes their pedals out of it. They're light and fast, but break, especially along the base plate in the center where the energy from the heel and from the toes (going in both directions) has the highest amplitude. And you can't tension the screws without stripping the hole. The parts are like butter.

Sonor giant step uses a steel base plate, and I've never stripped a screw hole. So no such issues.
