Il magnesio è l'elemento chimico della tavola periodica degli elementi che ha come simbolo Mg e come numero atomico 12. Il magnesio è l'ottavo elemento più abbondante e costituisce circa il 2% della crosta terrestre; inoltre è il terzo per abbondanza tra gli elementi disciolti nell'acqua di mare. In natura, per la sua elevata reattività, non esiste allo stato libero, ma si trova combinato con altri elementi. Questo metallo alcalino terroso è principalmente usato come agente legante nella produzione di leghe alluminio-magnesio.
