Yẹ Samarium koluboti oofa SmCo Magnet
Apejuwe ọja
Samarium-Cobalt oofa (SmCo) ni iye iwọn otutu Br ti o dara julọ (-0,035%/℃) fifun ni idawọle ti o ga julọ ti o wa loke iwọn otutu iṣẹ 150℃. Pelu idiyele ti o ga julọ ju awọn ohun elo oofa miiran lọ, SmCo n pese akojọpọ iyalẹnu ti agbara giga, iduroṣinṣin igbona, ati resistance ipata. Awọn ideri aabo ni gbogbogbo ko nilo ayafi fun awọn ohun elo kan pato. Ṣugbọn SmCo jẹ agaran ati ẹlẹgẹ: ti o ba ju silẹ, yoo fọ.
