Kajaba iku, magnet SmCo duwe fitur liyane:
Kinerja sing bisa dipercaya: Magnet SmCo tahan banget kanggo demagnetisasi, saengga bisa dipercaya ing akeh lingkungan.
Karat lan resistance oksidasi: Amarga isi wesi kurang ing materi gabungan, wesi sembrani SmCo duwe resistance karat banget.Boten kados NdFeB, SmCo wesi sembrani ora perlu electroplating.
Stabilitas suhu: SmCo bisa njaga gaya magnet ing suhu dhuwur (249-300 ℃) lan suhu sing sithik banget (-232 ℃).
Bahan brittle: Nalika ing sintering, materi uga brittle, amarga iku brittle lan gampang kanggo kokain, Processing wis watesan, kang cara Processing tradisional ora bisa digunakake.Nanging, bisa uga lemah, nanging mung yen akeh coolant digunakake.Iki amarga coolant bisa nyilikake risiko geni saka retak termal lan bledug grinding teroksidasi.
Aplikasi:
1. High-mburi PM motor.Motor PM umum biasane nggunakake magnet ferrite utawa magnet NdFeB.Nanging ing panggonan sing suhu ngluwihi 200 ℃ utawa torsi kios gedhe, mung motor SmCo PM sing kompeten.
2. Piranti electroacoustic ing sistem loudspeaker dhuwur-mburi.
3. Sistem instrumen sing dipercaya banget.Akeh instrumen sing digunakake ing aerospace, penerbangan, medis lan lapangan liyane kudu nggunakake magnet permanen SmCo kanggo njamin linuwih lan safety sing sampurna.
4. Ing sistem radar lan komunikasi sing penting banget, akeh tabung gelombang lelungan, magnetron, tabung chasing, tabung gelombang chasing, gyrotron lan piranti vakum listrik liyane digunakake, lan magnet SmCo nggawe sinar elektron ing sadawane dalan sing wis ditemtokake.
5. SmCo Magnetik extractors ing sumur jero ngisor 3000 meter, lan SmCo Magnetik drive (pump) ing lingkungan suhu dhuwur saka 200 ℃.
6. Kepala nyedhot Magnetik, separator Magnetik, bantalan Magnetik, NMR, etc.
