Holmium Foil is a thin foil of the rare earth metal holmium that we produce in 24 variations. Known for its high magnetic permeability even at high temperatures, holmium has applications in research magnets as well as magnetic bearings in turbines. It also offers corrosion resistance and a high melting point that makes this foil useful for high temperature electrodes. With its unique magnetic properties available in a wide range of sizes, our Holmium Foil range can meet the needs of research and development across a range of fields.
