vanadium statistics and information usgsvanadium, when present in small amounts in certain ferrous alloys, can significantly improve their properties. manufacturers of automobiles and machinery recognized the toughness and fatigue resistance of vanadium alloys as far back as the early 1900's, incorporating the alloys in axles, crankshafts, gears, and other critical components.

vanadinite uses and physical propertiesvanadinite, along with carnotite and roscoelite, are important ores of vanadium metal. vanadinite is also a minor ore of lead. both vanadium and lead are produced wherever vanadinite is mined. vanadinite is very popular as a specimen with mineral collectors. they enjoy its bright colors, showy hexagonal crystals, resinous color, and adamantine luster.
