| Kumbuka: · Tunasalia kama ilivyo hapo juu isipokuwa tu kama tumebainishwa na mteja. Mgawo wa halijoto ya Curie na halijoto ni kwa ajili ya marejeleo pekee, si kama msingi wa uamuzi. · Kiwango cha juu cha joto cha kufanya kazi cha sumaku kinaweza kubadilika kutokana na uwiano wa urefu na kipenyo na mambo ya mazingira. | |||||||||
Kipengele:
1. Sumaku ya AlNiCo ina uingizaji wa mabaki ya juu lakini nguvu ya chini. Inafanya kazi kwa utulivu kwa joto kali, kudumisha sifa zake za magnetic kati
-250ºC na 550ºC. Kulingana na induction ya juu ya sumaku, hutumiwa sana katika kupima vifaa na mifumo ya kugundua.
2. Alnico ni nyenzo dhaifu na inaweza tu kubadilishwa wakati wa mchakato wa kutupa. Mwelekeo wake uliopatikana wakati wa matibabu ya joto, huzalisha shamba la magnetic
na mwelekeo uliobainishwa wa sumaku.
3. Kutokana na nguvu ndogo ya kulazimisha, sumaku za AlNiCo zinaweza kuathiriwa kwa urahisi na nguvu ya sumaku ya nyuma na athari ya chuma. Ndiyo sababu wanaweza kufutwa kwa urahisi
kwa mvuto wa nje. Kwa sababu hii, sumaku za AlNiCo hazipaswi kuhifadhiwa na kupakiwa na miti sawa inayopingana.
4. Katika mzunguko wa wazi, mgawo wa urefu / kipenyo (L / D) unapaswa kuwa angalau 4: 1. Kwa urefu mfupi
5. Sumaku za AlNiCo hutenda vyema dhidi ya oxidation. Hakuna mipako inayohitajika kwa ulinzi wa uso.
Maombi:
Tumia katika bidhaa zenye usikivu wa hali ya juu kama vile Ala, Mita, Simu za mkononi, sehemu za Gari. Vifaa vya Electroacoustic, Motors, Kufundisha na Anga
kijeshi, nk.
Thamani zote zilizotajwa ziliamuliwa kwa kutumia sampuli za kawaida kulingana na IEC 60404-5. Vigezo vifuatavyo vinatumika kama maadili ya marejeleo na yanaweza kutofautiana.
