Magnet Samarium Cobalt Permanen Magnet SmCo
Deskripsi Produk
Magnet Samarium-Cobalt (SmCo) memiliki koefisien suhu Br terbaik (-0,035%/℃) yang memberikan induksi tersedia absolut lebih tinggi di atas suhu kerja 150℃.Meskipun biayanya lebih tinggi dibandingkan bahan magnetik lainnya, SmCo memberikan kombinasi luar biasa antara energi tinggi, stabilitas termal, dan ketahanan terhadap korosi.Lapisan pelindung umumnya tidak diperlukan kecuali untuk aplikasi tertentu.Namun SmCo sangat renyah dan rapuh: jika terjatuh, ia akan pecah.
