Salaku tambahan, magnet SmCo gaduh fitur anu sanés:
Kinerja dipercaya: SmCo magnet pisan tahan ka demagnetization sahingga bisa dipercaya dina loba lingkungan.
Korosi sareng résistansi oksidasi: Kusabab eusi beusi rendah dina bahan komposit, magnet SmCo gaduh résistansi korosi anu saé.Teu kawas NdFeB, SmCo magnét teu perlu electroplating.
Stabilitas suhu: SmCo tiasa ngajaga gaya magnét na dina suhu anu luhur (249-300 ℃) sareng suhu anu rendah pisan (-232 ℃).
Bahan rapuh: Nalika dina sintering, bahanna tiasa regas, kusabab éta rapuh sareng gampang rengat, pamrosésanna gaduh watesan, anu metode pangolahan tradisional henteu tiasa dianggo.Sanajan kitu, eta bisa jadi taneuh, tapi ngan lamun loba coolant dipaké.Éta sabab coolant tiasa ngaleutikan résiko seuneu tina retakan termal sareng lebu ngagiling anu dioksidasi.
Aplikasi:
1. High-tungtung PM motor.Motor PM umum biasana ngagunakeun magnet ferrite atanapi magnet NdFeB.Tapi di tempat dimana hawa ngaleuwihan 200 ℃ atawa torsi lapak badag, ngan motor SmCo PM kompeten.
2. Alat éléktroakustik dina sistem spiker high-end.
3. Sistim instrumen kacida dipercaya.Loba instrumen dipaké dina aerospace, aviation, médis sarta widang lianna kudu make SmCo magnet permanén pikeun mastikeun reliabiliti tinggi jeung kaamanan sampurna.
4. Dina radar penting pisan jeung sistem komunikasi, sajumlah badag tabung gelombang iinditan, magnetrons, chasing tabung, chasing tabung gelombang, gyrotrons jeung alat vakum listrik séjén dipaké, sarta magnet SmCo nyieun balok éléktron sapanjang gerak sapanjang jalur prescribed.
5. SmCo extractors magnét dina sumur jero handap 3000 méter, sarta SmCo drive magnét (pompa) dina lingkungan suhu luhur 200 ℃.
6. sirah nyeuseup magnét, separator magnét, bearing magnét, NMR, jsb.
