Terbium Metal 99.9% is the important additive for NdFeB permanent magnets to raise the Curie temperature and improve temperature coefficiency. Another most promising use of distilled Terbium Metal, code 6563D, is in the magnetostrictive alloy TEFENOL-D. There are also other applications for some special master alloys. The other main application is for making magnets.
