Application of Erbium Metal
Erbium Metal, is mainly metallurgical uses. Added to vanadium, for example, Erbium lowers hardness and improves workability. There are also a few applications for nuclear industry. Erbium Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, discs and powder.Erbium Metal is used as additives for hard alloys, non-ferrous metals, hydrogen storage matrix materials, and reducing agents for making other metals.
