You get a very exothermic redox reaction taking place - it’s known as the thermite reaction and is used in welding applications such as rail track laying.

With MnO2, the reaction equation is

3MnO2 + 3Al → 2Al2O3 + 3Mn
Molten metallic manganese is produced, along with aluminium oxide and a lot of heat energy.
