Which non-ferrous metal is described as light and hard?

Explanation:
The key idea is comparing metals by how light they are and how hard they feel in use. Titanium stands out because it has a low density, so it’s light, and it also offers high strength and hardness, especially in its common alloys, making it hard enough for demanding engineering tasks. Aluminium is light but softer, copper is heavier and more ductile (not as hard), and tin is relatively soft. So titanium best matches both lightness and hardness.
