Vanadium has a number of excellent physical properties and chemical properties, so the use of vanadium is very extensive, there is metal "vitamins" known. The initial vanadium is mostly used in steel, which improves the grain coarsening temperature by refining the microstructure and grain of the steel, thus increasing the strength, toughness and wear resistance of the steel. Later, the excellent improvement of vanadium in TI alloy was gradually discovered, and applied to the aerospace field, which made the aerospace industry make a breakthrough progress. With the rapid development of science and technology, the demand for new materials is increasing. Vanadium is more and more widely used in the field of non steel, including aerospace, chemistry, batteries, pigments, glass, optics, medicine and many other fields.

Can be distinguished metal-vanadium vanadium traces all over the world.
