Limiting Heavy Rare Earths Reliance for Neodymium Magnets
The growth in demand for neodymium-iron-boron (NdFeB) permanent magnets to maintain magnetic performance at high temperatures led to the inclusion of heavy rare earths such as dysprosium and terbium. The addition of these elements increases the coercivity of NdFeB i.e. it allows the magnets to operate at higher temperatures without losing their magnetic properties. The…
Read MoreRare Earth Magnets in Electric Vehicle Motors
The global move towards the electrification of vehicles continues to gather momentum. In 2010, the number of electric cars on the world’s roads reached 7.2 million, of which 46% were in China (iea.org/reports/global-ev-outlook-2020). By 2030, the number of electric cars is expected to swell to 250 million, a massive growth in a relatively short time.…
Read MoreMagnet Comparison: Neodymium and Samarium Cobalt Rare Earth Magnets
Neodymium Iron Boron NdFeB (i.e. Neodymium) and Samarium Cobalt SmCo are both ultra-strong rare-earth permanent magnets. Both are brittle in nature and subject to catastrophic damage if subject to severe impact (i.e. dropping). However, that is where the similarity ends and, when selecting a magnet material for a specific application, our design engineers assess each…
