Name a non-ferrous metal that is notably light.

Explanation:
Aluminium is notably light because it has a very low density for a metal. Its density is about 2.7 g/cm³, which is far lighter than copper (around 8.9 g/cm³), tin (about 7.3 g/cm³), or silver (about 10.5 g/cm³). Being non-ferrous means it doesn’t contain iron, and among common non-ferrous metals, aluminium’s lightness stands out. This combination—low density with good strength—explains why aluminium is the go-to choice when keeping weight down is important.
