Abũbuwan amfãni da rashin amfani na Sm2Co17 da SmCo5 m Magnetic kayan

Idan aka kwatanta da SmCo5, daSm2Co17yana da fa'idodi masu zuwa:

1. A abun ciki na cobalt da samarium a cikin dabara na Sm2Co17 m Magnetic abu ne m fiye da na SmCo5 m Magnetic abu, wanda ƙwarai kubutar da kudin da albarkatun kasa.Domin samarium da cobalt albarkatun kasa ne in mun gwada tsada rare karafa, don haka farashin Sm2Co17 m maganadisu abu ne m fiye da na SmCo5;

2. The Magnetic shigar zazzabi coefficient na Sm2Co17 m Magnetic abu ne game da -0.02% / ℃, shi zai iya aiki a cikin kewayon -60 ~ 350 ℃, wanda shi ne m zuwa SmCo5 m Magnetic abu;

3.Curie zafin jiki yana da girma.The Curie batu na Sm2Co17 abu ne game da 840 ~ 870 ℃, da kuma Curie batu na SmCo5 abu ne 750 ℃.Wannan yana nufin cewa Sm2Co17 ya fi juriya ga yanayin zafi fiye da SmCo5.Duk da haka, idan aka kwatanta da SmCo5 m Magnetic abu, da masana'antu tsari na Sm2Co17 ne mafi rikitarwa.Don inganta haɓakawa, dole ne a tsufa don lokuta masu yawa, kuma farashin tsari ya fi na SmCo5.A cikin m maganadisu, Sm2Co17 Magnetic abu ne wani irin m maganadisu tare da m high sabis zafin jiki.

Saboda karuwar buƙatun maganadisu na dindindin da aka yi amfani da su sama da 400 ℃ a cikin sararin samaniya da masana'antar lantarki, jama'a suna maraba da kayan magnetic dindindin tare da zazzabi mai sabis da ingantaccen aiki.Ko da yake yawan zafin jiki na Alnico na dindindin maganadisu yana sama da 500 ℃, ƙarfin ƙarfin sa ya yi ƙasa kaɗan don biyan buƙatun amfani mai amfani.NdFeb rare duniya m maganadisu jiki yana da high coercivity da kuma mai kyau m yi, amma amfani zafin jiki ba zai iya saduwa da sama bukatun, saboda low Curie zafin jiki da kuma babban zazzabi coefficient.Saboda kyakkyawan aikin sa, Sm2Co17 kayan magnetic na dindindin an yi amfani dashi sosai a cikin motar, kayan aiki daidai, na'urar microwave, firikwensin, ganowa da sauran manyan filayen fasaha.
