ndfeb(Nd - Fe - B)

Permanent magnetic materialIt's mainly aluminum, nickel, cobalt(AlNiCo)Metal permanent magnet, first generationSmCo5A permanent magnet

(Referred to as1:5Samarium cobalt ii alloy)And the second generationSm2Co17 (Referred to as2:17Samarium cobalt ii alloy)Permanent magnet,

Third generation rare earth permanent magnetic alloyNdFeB (It's called ndfeb). With the development of science and technology, neodymium

The properties of ferroboron permanent magnetic materials have been improved and their application fields have been expanded. High magnetic energy product (50Trillion gaussian

Material 400 kj/m3), high coercivity (28 eh,32 eh) and high service temperature (240 c)

Sintered ndfeb has been industrialized production. The main raw material of ndfeb permanent magnet is the rare earth metal neodymium (Nd

)32%, metallic element iron (Fe)64%And boron (B)1%(small amount added

Dysprosium (Dy), terbium (Tb), cobalt (Co), niobium (Nb), gallium (The Ga), aluminum (Al),

Copper (Cu), etc. Ndfeb ternary permanent magnet material isNd2Fe14Bcompound
