L' aluminium est un métal non-ferreux largement utilisé en métallerie. C'est un matériau très léger. De fait, sa densité est d'environ 2,7 g/cm3, alors que l'inox a une densité de 8 g/cm3. C'est pourquoi l'aluminium est parfois préféré pour cette qualité de légèreté, notamment dans les avions ou les navires.
