Abstract

Des alliages magnetiques au Fe-Cr-Co contiennent en plus Cu. Des alliages de Fe-Cr-Co-Cu d'aimants permanents contiennent de preference 22-38% en poids de Cr, 3-30% en poids de Co, 0,2-5% en poids de Cu, le reste etant essentiellement du fer. La presence en quantites limitees d'autres elements tels que par exemple des elements de stabilisation de ferrite ou des elements de terres rares n'est pas ecartee. Les nouveaux alliages ont des proprietes magnetiques superieures telles que, d'une maniere caracteristique, une remanence (Br) dans une plage de 8.000-14.000 gauss, une force coercive (Hc) dans une plage de 200-1.500 oersted (15.920-119.400 A/m), et un produit energetique (BH)max. dans une plage de 1,0-15,0 millions de gauss-oersted (79,6-894 MG.A/m). Ces alliages peuvent etre traites pour obtenir des proprietes magnetiques isotropes ou anisotropes.
