Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard silvery-grey malleable transition metal.The elemental metal is rarely found in nature but once isolated artificially the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation..

Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals at approximately one third that of steel has a great affinity towards oxygen and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver both in its color and
