Vanadium (V) is a hard but malleable silver-grey metal. It rarely occurs in nature in its pure metallic form, but is commonly found as a compound in other minerals. Vanadium-bearing minerals, such as vanadinite (Pb 5 (VO 4) 3 Cl), patronite (VS 4) and carnotite (K 2 (UO 2) 2 (VO 4) 2 ·3H 2 O) have been mined historically.

Vanadium-steel alloys are very tough and are used for armour plate, axles, tools, piston rods and crankshafts. Less than 1% of vanadium, and as little chromium, makes steel shock resistant and vibration resistant. Vanadium alloys are used in nuclear reactors because of vanadium's low neutron-absorbing properties.
