Elemental aluminium reduces the oxide of another metal, in this common example iron oxide, because aluminium forms stronger and more stable bonds with oxygen than iron:
Fe2O3 + 2 Al → 2 Fe + Al2O3

In thermite welding aluminium powder is used along with ferric oxide. Aluminium has more affinity towards oxygen and it reduces ferric oxide to elemental iron during welding and also produces lot of heat. The molten elemental iron thus formed will seal the broken parts to have a strong bonding.
