Uea/ Kaha/Koʻokoʻo o ka Mu 49 (FeNi50)

ʻO ka hao nickel hao magnetic palupalu i loko o ke kumu nickel hao me nā helu like ʻole o Co, Cr, Cu, Mo, V, Ti, Al, Nb, Mn, Si a me nā mea ʻē aʻe o ke alloy, ʻo ia ka mea maʻalahi loa o ke kola hao nickel, kahi ʻano o nā ʻano like ʻole a me nā kikoʻī, dosage ma hope o ka pepa kila silicon a me ka hao maʻemaʻe uila. Ke hoʻohālikelike ʻia me nā kola magnetic palupalu ʻē aʻe, ʻo ke kola i ke kahua geomagnetic he kiʻekiʻe loa ka permeability magnetic a me ka ikaika coercive haʻahaʻa, aia kekahi mau kola i ka loop hysteresis rectangular, a i ʻole ka ikaika induction magnetic koena haʻahaʻa loa a me nā ʻano permeability magnetic mau a he kumu kūikawā.
Loaʻa i kēia ʻano metala nā waiwai anti-rust maikaʻi a me nā waiwai hana, ke ʻano a me ka nui hiki ke hana i nā ʻāpana kikoʻī loa. No ka mea, ʻoi aku ke kiʻekiʻe o ka resistivity o ka metala ma mua o ka hao maʻemaʻe a me ka pepa kila silicon, a maʻalahi hoʻi e hana ʻia i kāʻei lahilahi, no laila ma lalo o kekahi mau microns kāʻei lahilahi, e pili ana i kekahi mau MHZ ma ke alapine kiʻekiʻe.
ʻOi aku ka kiʻekiʻe o ka ikaika o ka induction magnetic saturated a me ka mahana Curie o ka alloy ma mua o nā mea magnetic ferrite palupalu, i ka ʻoihana aerospace a me nā ʻoihana uila ʻē aʻe e hana i ka ʻike kiʻekiʻe, ka pololei o ka nui, ka nui liʻiliʻi, ka pohō haʻahaʻa ma ke alapine kiʻekiʻe, ka paʻa o ka manawa a me ka mahana a me ka hana o nā ʻāpana uila kūikawā. I ke kamaʻilio ʻana, nā mea hana, nā kamepiula uila, ka mana mamao, ka ʻike mamao a pēlā aku ua hoʻohana nui ʻia i loko o ka ʻōnaehana.

Aia nā mea hoʻohuihui magnetic palupalu i loko o kahi kahua magnetic nāwaliwali me ka permeability kiʻekiʻe a me ka ikaika coercive haʻahaʻa o nā mea hoʻohuihui. Hoʻohana nui ʻia kēia ʻano mea hoʻohuihui i nā uila lekiō, nā mea hana pololei a me nā mika, ka mana mamao a me ka ʻōnaehana hoʻokele aunoa, hoʻohana nui ʻia ka hui ʻana no ka hoʻololi ikehu a me ka hana ʻike, ʻo nā ʻano ʻelua o kahi mea nui i ka hoʻokele waiwai aupuni.

Maʻalahi ka magnetization o ke kahua magnetic waho ma lalo o ka hana a ka mea makeneka palupalu, a nalowale ke kahua magnetic a me nā mea makeneka ma hope o ka wehe ʻana i ke kahua makeneka.
He liʻiliʻi a haiki ka wahi o ka loop hysteresis, ʻoi aku ka ikaika coercive ma mua o 800 a/m, resistivity kiʻekiʻe, liʻiliʻi ka pohō o ke au eddy, permeability kiʻekiʻe, induction magnetic saturation kiʻekiʻe. Hoʻoponopono nui ʻia i loko o nā pepa a me nā ʻāpana. Ua hoʻomākaukau ʻia ka heheʻe. Hoʻohana nui ʻia no nā mīkini uila, nā ʻoihana kelepona i nā ʻāpana koʻikoʻi like ʻole (e like me ke kumu hoʻololi, ka relay iron core, ka choke coil, a pēlā aku). ʻO ka mea maʻamau i hoʻohana ʻia he kila uila kalapona haʻahaʻa, ka hao eminem, ka pepa kila silicon, ka mea hao magnetic palupalu, ka hao, ka cobalt soft magnetic alloy, ka nickel iron iron silicon soft magnetic alloy, a pēlā aku.

Ma lalo o ka hana o ke kahua magnetic waho ma hope o ka magnetization maʻalahi, koe wale nō ke kahua magnetic o ka ikaika induction magnetic (magnetic induction) a me ka nalo ʻana o ka alloy magnetic. He liʻiliʻi a haiki ka wahi loop Hysteresis, ʻoi aku ka ikaika coercive (Hc) ma mua o 10 Oe (e ʻike i ka precision alloy). I ka hopena o ke kenekulia 19, ua hana ʻia me ke kila kila kalapona haʻahaʻa a me ke kumu transformer. 1900, ua pani koke ka pepa kila silicon kiʻekiʻe magnetic i ke kila haʻahaʻa-kalapona, i hoʻohana ʻia i ka hana ʻana i nā huahana ʻoihana mana uila. I ka makahiki 1917, ua hoʻololi ka Ni - Fe alloy i nā pono o kēia manawa o ka ʻōnaehana kelepona. A laila, ʻo ka Fe - Co alloy me nā waiwai magnetic like ʻole (1929), Fe - Si - Al alloy (1936) a me Fe - Al alloy (1950) e hoʻokō i ke kumu kūikawā. I ka makahiki 1953, ua hoʻomaka ʻo Kina i ka hana ʻana o ka pepa kila silicon i ʻōwili wela ʻia. I ka hopena o nā makahiki 50 a ua hoʻomaka e aʻo iā Ni - Fe a me nā alloy magnetic palupalu e like me Fe, Co, 60 s i hoʻomaka mālie e hana i kekahi o nā alloy magnetic palupalu nui. I ka makahiki 70, ua hana ʻia ke anuanu i ʻōwili ʻia kāʻei kila silicon.
ʻO nā waiwai magnetic o ka alloy magnetic palupalu: (1) ka ikaika coercive (Hc) a me nā pohō hysteresis haʻahaʻa (Wh); (2) ʻoi aku ke kiʻekiʻe o ka resistivity (rho), haʻahaʻa ka pohō eddy current (We); (3) permeability mua (mu 0) a me ke kiʻekiʻe kiʻekiʻe loa

ʻO nā ʻano nui o
Hiki ke hoʻokaʻawale ʻia i ke kila uila haʻahaʻa kalapona a me ka hao eminem, ka pepa kila silicon, ka hao nickel palupalu magnetic alloy, ka hao, ka cobalt palupalu magnetic alloy, ka hao, ka silicon alumini palupalu magnetic alloy, a pēlā aku, ma ke ʻano o ka ʻoihana mana uila, hoʻohana nui ʻia i ke kahua magnetic kiʻekiʻe me ka induction magnetic kiʻekiʻe a me ka pohō kumu haʻahaʻa o ka alloy. I ka ʻoihana uila, hoʻohana nui ʻia i ke kahua magnetic haʻahaʻa a waena paha me ka permeability kiʻekiʻe a me ka coercivity haʻahaʻa o ka alloy. Ma lalo o ke alapine kiʻekiʻe e pono e hoʻohana i ke kaula lahilahi a i ʻole ke kū'ē kiʻekiʻe o ka alloy. Hoʻohana pinepine ʻia ka pepa a i ʻole ke kaula.
