ʻO nā mea Alnico (haku ʻia o ka aluminika, nickel, a me ka cobalt me ​​nā mea liʻiliʻi ʻē aʻe e like me ka titanium a me ke keleawe) ʻae ʻia nā latitude hoʻolālā e hāʻawi ana i nā hōʻailona kiʻekiʻe, nā ikaika kiʻekiʻe a me nā coercivities kiʻekiʻe. Hoʻohālikelike ʻia nā mākēneki Alnico e ke kūpaʻa o ka mahana maikaʻi a me ke kūpaʻa maikaʻi i ka demagnetization mai ka haʻalulu a me ka haʻalulu. Hāʻawi nā magnets Alnico i nā ʻano wela ʻoi loa o kēlā me kēia kumuhana hana magnet i loaʻa. Hiki iā lākou ke hoʻohana no nā noi hana mau kahi e manaʻo ʻia ai ka mahana loa a hiki i ka 930F.

Hana ʻia nā mākēneki Alnico ma o ka hoʻolei ʻana a i ʻole ke kaʻina hana hewa. Paʻakiki loa a palupalu ʻo Alnico magnet. ʻAʻole hiki ke hoʻokō ʻia ka mīkini a ʻeli ʻana paha e nā ʻano maʻamau. Hoʻopaʻa pinepine ʻia nā puka i loko o ka waihona. Mākēneki e hoʻolei 'ole sinter e like me ka hiki i koi' ia ka nui a hiki i ka abrasive wili e hoʻopau ana a me ke ahonui e hoʻoliʻiliʻi

Hoʻohana ʻia nā hana hoʻolei hana kūikawā e hoʻokō ai i ka ʻike kū hoʻokahi crystalline palaoa i loaʻa ma ka papa alnico 5 a me 8. Hoʻonohonoho ʻia kēia mau papa anisotropic e hana i nā huahana magnet kiʻekiʻe i kahi kuhikuhi i kuhikuhi ʻia. Loaʻa ka orientation i ka wā o ka mālama ʻana i ka wela, e ka hōʻoluʻolu ʻana i ka ninini ʻana mai 2000F ma kahi helu i kāohi ʻia i loko o kahi māla uila e kūlike i ka ʻaoʻao i makemake ʻia o ka magnetization. ʻO Alnico 5 a me Alnico 8 he anisotropic a hōʻike i kahi ʻaoʻao i makemake ʻia o ke kuhikuhi, e kikoʻī ʻia ke ʻano Mākēneki i kāu kaha kiʻi ke hoʻouna ʻoe i kahi kauoha iā mākou.

ʻO Cast Alnico 5 ka mea i hoʻohana mau ʻia o nā cast Alnico's a pau. Hoʻohui ia i nā hōʻailona kiʻekiʻe me kahi huahana ikehu kiʻekiʻe o 5 MGOe a ʻoi a hoʻohana pinepine ʻia i nā mīkini hoʻohuli, nā kamaʻilio, nā mika a me nā mea kani, ʻike i nā hāmeʻa a me ka hoʻopaʻa ʻana i nā noi. ʻO ke kūpaʻa kiʻekiʻe aʻe i ka demagnetization (kaohi coercive) o Alnico 8, nā mea cobalt i 35%, hiki i kēia mea ke hana maikaʻi no nā lōʻihi pōkole a i ʻole ka lōʻihi i ke anawaena o ke anawaena ma lalo o 2 a 1.

Hāʻawi nā mea Sintered Alnico i nā pono ʻume mākenēki haʻahaʻa akā ʻo nā ʻano mīkini mole ma mua o ka hoʻolei ʻana i nā mea Alnico. Kūpono loa nā mākēneki Sintered Alnico i nā liʻiliʻi liʻiliʻi (ma lalo o 1 oz.) I kēia kaʻina. ʻO ka hui ʻana o ka pauka metala i makemake ʻia e kaomi ʻia i ke kinona a me ka nui i ka make, a laila sinter ma 2300 F i kahi lewa hydrogen. Kūpono ke kaʻina hana sinter i ka hana nui o ka leo, a me nā hopena i nā ʻāpana i ʻoi aku ka ikaika ma mua o nā mākēneki kiloi. Hiki ke hoʻokō ʻia nā hoʻomanawanui pili loa me ka wili ʻole ʻana.

'Apono kūpono:
Nā hiʻohiʻona o Alnico Mākēneki:

* Nā loli liʻiliʻi i nā pono magnet i nā hopena wela
* ʻO ke kiʻekiʻe o ka mahana hana e hiki ke kiʻekiʻe ma mua o 450oC ~ 550oC.
* Kaohi koi haʻahaʻa.
* Hiki i ka pale kūpaʻa kūpaʻa paʻa, ʻaʻohe pale e pono ai no ka pale o luna.

• kūpono no nā mākēneki liʻiliʻi liʻiliʻi me ke ʻano paʻakikī
• Ke aniani kuikahi, ikaika nui
• Kūlana maʻamau, ka nui kikoʻī
• ʻOiai nā mea, hana paʻa
• Kūpono no ka magnet magnet
• ʻO ke kūpaʻa wela maikaʻi loa (temp. Coefficient o Br ka mea liʻiliʻi loa ma waena o nā mākēneki paʻa mau ʻē aʻe
