Dysprosium Metal is an important additive for NdFeB permanent magnets to raise the Curie temperature and improve temperature coefficiency. Another most promising use of high purity Dysprosium Metal is in the magnetostrictive alloy TEFENOL-D. There are also other applications for some special master alloys. Dysprosium Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, discs and powder. It is highly susceptible to magnetization, they are employed in various data-storage applications, such as in hard disks.
