Incazelo emfushane:

Okokuqala kwavela ekuqaleni kwawo-1970, uzibuthe we-FeCrCo noma uzibuthe we-Iron Chromium Cobalt wakhiwa i-Iron, i-Chromium, ne-Cobalt. Okuhle okubalulekile kozibuthe be-Fe-Cr-Co amathuba okubumba angabizi kakhulu.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izinto ezisetshenziswayo ziyi-vacuum melt to alloy ingot, khona-ke izingosi zengxubevange zingenziwa ngomshini ngokuginqika okushisayo, ukugoqa okubandayo kanye nazo zonke izindlela zomshini zokubhola, ukujika, ukubhora, njll. ukuze kulolonge omazibuthe be-FeCrCo. Ozibuthe be-FeCrCo banezici ezifanayo ezinozibuthe be-Alnico njenge-Br ephezulu, i-Hc ephansi, izinga lokushisa eliphezulu lokusebenza, ukuzinza okuhle kwezinga lokushisa nokumelana nokugqwala, njll.

Kodwa-ke, omazibuthe be-FeCrCo abangapheli baziwa ngokuthi ama-transformer kumamagnet angunaphakade. Kulula ukucutshungulwa kwensimbi, ikakhulukazi ukudweba ngocingo nokudweba kweshubhu. Lokhu kuyinzuzo abanye omagnethi baphakade abakwazi ukuqhathanisa nayo. Ama-alloys e-FeCrCo angashisa kalula futhi enziwe ngomshini. Cishe akukho ukulinganiselwa komumo nobukhulu bazo. Zingenziwa zibe izingxenye zomumo ezincane neziyinkimbinkimbi ezifana nebhulokhi, ibha, ishubhu, i-strip, ucingo, njll. Ububanzi bazo obuncane bungafinyelela ku-0.05mm futhi ukuqina kwe-thinnest kufinyelela ku-0.1mm, ngakho-ke afanele ukukhiqizwa okuphezulu- ukunemba izingxenye. Izinga lokushisa eliphezulu leCurie lingaba ngu-680°C kanti izinga lokushisa eliphakeme kakhulu lokusebenza lingaba phezulu lifike ku-400°C.
