SHEET MAT-01
Figure 1. Representative trace for this section, drawn to show the shape of the decision it holds. Values shown on each sheet are supplied against your own specification.
Compare the materials behind magnetic performance.
Rare-earth inputs and alternative permanent-magnet materials each solve different engineering and supply-chain requirements.
NdPr
Neodymium-praseodymium products in the upstream NdFeB value chain.
Explore01.02Dysprosium
A heavy rare-earth element used to improve high-temperature demagnetisation resistance.
Explore01.03Terbium
A strategic material associated with high-performance thermal stability.
Explore01.04Ferrite
A cost-effective alternative where size and maximum energy density are less critical.
Explore01.05SmCo
High-temperature and corrosion-resistant performance for demanding environments.
Explore01.06Alnico
A long-established permanent-magnet material with strong temperature characteristics.
ExploreMetals specified for more than magnetism.
Alloying, catalytic and energy-storage materials are bought on composition, purity and process performance — a different set of decisions from permanent-magnet selection.
