More info
Erbium (Er) Metal is a rare earth element with atomic number 68 and the symbol Er. It does not oxidize as rapidly as some of the other rare earth metals as it is fairly stable in air. It has a high electrical resistivity. HM stocks various rare earth materials for use in electronics, petrochemicals, metallurgy, machinery, energy, environmental protection, agriculture, and other fields. We also offer pure metals and compounds for R&D applications.
