"Actually, aluminum is extremely reactive, and any bare surface instantly
grows a microscopic oxide layer (corundum) that is air tight and prevents
further oxidation. In extreme heat, aluminum can begin to burn (similarly
to magnesium), and can even burn under water by stealing the oxygen from
water. The mixture called thermite is powdered aluminum and iron oxide.
When ignited, the aluminum steals the oxygen from the rust, generating a
great deal of heat and leaving molten iron. Also, powdered aluminum is a
primary ingredient in slow explosives such as fireworks. "

"Most solid rockets burn a mixture of ammonium perchlorate and aluminum
held together by a rubbery polymer. "
