Alnico Magnet ni sumaku ya aloi ya Aluminium, Nickel, Cobalt, Iron na vipengele vingine vya kufuatilia vya chuma, ambayo ni kizazi cha kwanza cha nyenzo za kudumu za sumaku ambazo zilitengenezwa hapo awali.
Vifaa vya Magnet vya Kudumu vya Alnico vina faida ya Br ya juu (hadi 1.5T) na mgawo wa joto la chini, magnetic imara, upinzani wa joto la juu, upinzani wa unyevu na upinzani wa oxidation.Wakati mgawo wa halijoto ni -0.02%/℃, kiwango cha juu cha halijoto cha kufanya kazi kinaweza kufikia 550℃.Ubaya ni kwamba shurutisho iko chini sana na mkondo wa demagnetization hauna mstari.Kwa hivyo, ingawa sumaku za Alnico zina sumaku kwa urahisi, pia ni rahisi kuondoa sumaku.
Kulingana na mchakato wa uzalishaji, inaweza kugawanywa katika Sintered Alnico na Cast Alnico.Sura ya bidhaa ni zaidi ya pande zote na mraba.Mchakato wa kutupwa unaweza kusindika kwa ukubwa na maumbo tofauti;
Ikilinganishwa na mchakato wa kutupa, bidhaa ya sintered ni mdogo kwa bidhaa za ukubwa mdogo.Uvumilivu wa mwelekeo wa nafasi zilizoachwa wazi ni bora kuliko ule wa bidhaa iliyopigwa wakati sifa za sumaku ziko chini kidogo kuliko ile ya bidhaa iliyopigwa.
Alnico sasa inatumika sana katika ala za magnetoelectric, flowmeters za sumakuumeme, relays, ala za kufundishia, pickups za gitaa la umeme, maikrofoni, vitambuzi, mirija ya mawimbi ya kusafiri, sumaku za ng'ombe na nyanja zingine.

Kumbuka: Halijoto ya Curie na mgawo wa halijoto hutumika kama marejeleo pekee, si kama vigezo vya hukumu.Wateja wana mahitaji maalum, yanaweza kubinafsishwa kulingana na mahitaji ya mteja. |
