Rare earths in magnets
Neodymium, praseodymium, dysprosium, terbium and samarium in magnets
The five pages explain the roles these elements may play in NdFeB or SmCo magnets. Relevant specialist links provide further information about metals, oxides, compounds and element-specific prices.
Five elements
The roles of the elements in permanent-magnet materials.
The application or temperature class alone does not establish a fixed element content. Batch documentation or suitable analysis is decisive.
Important limitation
Magnet mass is neither element mass nor oxide mass
A complete magnet consists of a material phase, a coating and, where applicable, composite components. Its total weight, magnet grade or application does not establish an element-specific purchase value.
Holmium is not a common standalone magnet category for this purchasing service. A device associated with holmium or a magnetised holder establishes neither holmium in the magnet nor a holmium alloy.
