.
Pure erbium metal is soft and malleable and has a bright, silvery, metallic lustre. As with other rare-earth metals, its properties depend to a certain extent on impurities present. The metal is fairly stable in air and does not oxidise as rapidly as some of the other rare-earth metals, mainly metallurgical uses; added to vanadium, for example, erbium lowers hardness and improves workability; also a few applications for nuclear industry.
