Permanen Samarium Kobalt Magnet SmCo Magnet
Deskripsi Produk
Magnetik Samarium-Kobalt (SmCo) duwe koefisien suhu Br paling apik (-0,035% / ℃) menehi induksi sing luwih dhuwur ing ndhuwur suhu kerja 150 ℃. Sanajan biaya sing luwih dhuwur tinimbang bahan magnetik liyane, SmCo nyedhiyakake kombinasi energi sing dhuwur, stabilitas termal, lan tahan karat. Lapisan protèktif umume ora dibutuhake kajaba kanggo aplikasi tartamtu. Nanging SmCo banget garing lan rapuh: yen sampeyan nyelehake, bakal pecah.
