Magnet Kobalt Samarium (Magnet SmCo)
Penerangan Produk
Magnet Samarium-Kobalt (SmCo) mempunyai pekali suhu Br terbaik (-0,035%/℃) memberikan aruhan tersedia yang lebih tinggi mutlak melebihi 150℃ suhu kerja.Walaupun kos yang lebih tinggi daripada bahan magnetik lain, SmCo menyediakan gabungan tenaga tinggi, kestabilan haba dan rintangan kakisan yang luar biasa.Salutan pelindung biasanya tidak diperlukan kecuali untuk aplikasi tertentu.Tetapi SmCo sangat rangup dan rapuh: jika anda menjatuhkannya, ia akan pecah.
