Les aimants en n\u00e9odyme standard peuvent r\u00e9sister \u00e0 des temp\u00e9ratures allant jusqu\u2019\u00e0 80 \u00b0C. Lorsqu\u2019ils sont expos\u00e9s \u00e0 des temp\u00e9ratures au-del\u00e0 de ce seuil, m\u00eame pendant une courte p\u00e9riode, leurs propri\u00e9t\u00e9s magn\u00e9tiques sont alt\u00e9r\u00e9es et affaiblies. Selon l\u2019intensit\u00e9 de la chaleur et la dur\u00e9e, ces dommages peuvent \u00eatre permanents et irr\u00e9versibles.<\/p>

Pour cette raison, nous recommandons fortement de choisir un aimant en n\u00e9odyme \u00e0 tol\u00e9rance \u00e9lev\u00e9e \u00e0 la temp\u00e9rature, ou de passer \u00e0 des aimants en ferrite, SmCo ou Alnico face \u00e0 des applications \u00e0 haute temp\u00e9rature.<\/p>

Dans l\u2019ensemble, les aimants en Alnico<\/strong> offrent la r\u00e9sistance \u00e0 la temp\u00e9rature la plus \u00e9lev\u00e9e parmi les aimants permanents, jusqu\u2019\u00e0 650 \u00b0C sans subir de perte de performance. Le seul inconv\u00e9nient est leur force d\u2019attraction relativement faible, qui est assez inf\u00e9rieure au n\u00e9odyme.<\/p>

Les aimants en SmCo<\/strong> offrent un \u00e9quilibre int\u00e9ressant entre la r\u00e9sistance \u00e0 la chaleur et la force d\u2019attraction. En fait, ils ne sont que l\u00e9g\u00e8rement plus faibles que les aimants n\u00e9odyme courants, tout en offrant une excellente r\u00e9sistance \u00e0 la corrosion et une temp\u00e9rature maximale de 350 \u00b0C.<\/p>

Enfin, les aimants en ferrite<\/strong> sont une bonne alternative \u00e0 un prix plus comp\u00e9titif, \u00e9tant tr\u00e8s r\u00e9sistants \u00e0 la corrosion, \u00e0 l\u2019humidit\u00e9 et \u00e0 l\u2019oxydation. Ils peuvent r\u00e9sister \u00e0 des temp\u00e9ratures allant jusqu\u2019\u00e0 250 \u00b0C.<\/p>

Les aimants en n\u00e9odyme<\/strong> sont les plus sensibles aux temp\u00e9ratures \u00e9lev\u00e9es et peuvent \u00eatre facilement endommag\u00e9s. Le seuil standard est de 80 \u00b0C. Il est en effet possible de les fabriquer avec des traitements sp\u00e9cifiques pour augmenter leur r\u00e9sistance. Ceux-ci sont indiqu\u00e9s par une lettre dans le nom, apr\u00e8s leur grade : un aimant \u00ab H \u00bb est con\u00e7u pour fonctionner \u00e0 des temp\u00e9ratures allant jusqu\u2019\u00e0 120 \u00b0C, \u00ab SH \u00bb jusqu\u2019\u00e0 150 \u00b0C, \u00ab UH \u00bb jusqu\u2019\u00e0 180 \u00b0C, \u00ab EH \u00bb jusqu\u2019\u00e0 200 \u00b0C.<\/p>
