ʻO ka haku mele ʻana o AlNiCo
Alnico magnetsʻO ia kekahi o nā mea i hoʻomohala mua ʻia he mea magnet mau loa, he mea hoʻohuihui i haku ʻia me ka aluminika, nickel, cobalt, hao a me nā mea metala ʻē aʻe. Ua hoʻomohala maikaʻi ʻia nā mea magnet permanent Alnico i nā makahiki 1930. Ma mua o ka hana ʻana i nā mea hoʻonaninani mau loa i nā makahiki 1960, ʻo ka aluminika-nickel-cobalt alloy ka mea ikaika loa, akā ma muli o ka hoʻokumu ʻana o nā metala koʻikoʻi cobalt a me nickel, e hopena i nā kumukūʻai kiʻekiʻe, me ka hiki ʻana mai o ferrite mau mākēneki mau a me ka honua laha ʻole, nā mea aluminika-nickel-cobalt i nā noi he nui i hoʻololi mālie ʻia. Eia naʻe, i kekahi mau kiʻekiʻe-mahana noi akiʻekiʻe magneticnā koi kūpaʻa, noho mau ka magnet i kahi kūlana unshakable.
ʻO ke kaʻina hana a me ka brand Alnico
Alnico magnetsloaʻa i nā kaʻina hana ʻelua o ka hoʻolei ʻana a me ka sintering, a hiki ke hana ʻia ke kaʻina hoʻolei i nā ʻano nui a me nā ʻano like ʻole; Ke hoʻohālikelike ʻia me ke kaʻina hana hoʻolei, ua kaupalena ʻia ka huahana sintered i kahi liʻiliʻi liʻiliʻi, ʻoi aku ka maikaʻi o ka hoʻomanawanui ʻana o ka blank i hana ʻia ma mua o ka blank product cast, ʻoi aku ka haʻahaʻa o ka waiwai magnetic ma mua o ka huahana hoʻolei, akā ʻo ka machinability. ʻoi aku ka maikaʻi.
ʻO ke kaʻina hana o ka hoʻolei ʻana i ka nickel cobalt aluminika e hui pū ana → hoʻoheheʻe → hoʻolei → hoʻomaʻamaʻa wela → hoʻāʻo hana → mīkini → nānā → hoʻopili.
Hoʻokumu ʻia ka nickel cobalt alumini sintered e ka pauka metallurgy, ke kaʻina hana e hoʻopaʻa ʻia → hana ʻana i ka pauka → kaomi → sintering → hoʻomaʻamaʻa wela → hoʻāʻo hana → machining → nānā → hoʻopili.
ʻO ka hana a AlNiCo
He kiʻekiʻe ke koena o ke koena o kēia mea, a hiki i ka 1.35T, akā haʻahaʻa loa ko lākou coercivity intrinsic, ʻoi aku ka liʻiliʻi ma mua o 160 kA/m, ʻo kona demagnetization curve he hoʻololi nonlinear, a ʻaʻole like ka alumini nickel cobalt permanent magnet loop. me ka pihi demagnetization, no laila pono e uku ʻia ka manaʻo kūikawā i kona kikoʻī i ka wā e hoʻolālā a hana ana i ke kaapuni magnetic o ka hāmeʻa. Pono e hoʻopaʻa ʻia ka magnet mau ma mua. No ka laʻana o ka anisotropic waena AlNiCo alloy, ka haku mele o Alnico-6 he 8% Al, 16% Ni, 24% Co, 3% Cu, 1% Ti, a me ke koena Fe. ʻO ka Alnico-6 he BHmax o 3.9 megagauss-oesteds (MG·Oe), he coercivity o 780 oersted, kahi mahana Curie o 860 °C, a me ka wela hana kiʻekiʻe o 525 °C. E like me ka haʻahaʻa haʻahaʻa o Al-Ni-Co mau mea magnet paʻa, ua pāpā loa ʻia ke hoʻopili ʻana me kekahi mea ferromagnetic i ka wā o ka hoʻohana ʻana, i ʻole e hoʻokau i ka demagnetization irreversible kūloko a i ʻole distortion o.hoʻoheheʻe magneticmahele mānoanoa.
Eia kekahi, i mea e hoʻoikaika ai i kona kū'ē demagnetization, ua hoʻolālā pinepine ʻia ka ʻili o ka Alnickel-cobalt permanent magnet pole me nā kolamu lōʻihi a i ʻole nā koʻokoʻo lōʻihi, no ka mea, ʻo ka alnickel-cobalt permanent magnet material he haʻahaʻa mechanical ikaika, kiʻekiʻe paʻakikī a me ka brittleness, ka hopena. i ka machinability maikaʻi ʻole, no laila ʻaʻole hiki ke hoʻolālā ʻia ma ke ʻano he ʻāpana hoʻolālā, a hiki ke hoʻohana ʻia kahi liʻiliʻi liʻiliʻi o ka wili a i ʻole EDM, a ʻaʻole hiki ke hoʻohana ʻia ka forging a me nā mea hana ʻē aʻe. Loaʻa iā Hangzhou Magnet Power Technology Co., Ltd. ka mana wili pololei o kēia huahana, hiki ke hoʻomalu ʻia ka pololei o ka hoʻoili ʻana i loko o +/-0.005 mm, a loaʻa iā ia ka hana a me ka hana ʻana o nā huahana kūikawā, inā he huahana maʻamau a i ʻole. nā huahana kūikawā kūikawā, hiki iā mākou ke hāʻawi i ke ala kūpono a me ka papahana.
Nā wahi noi o Alnico
Hoʻohana nui ʻia nā huahana alumini-nickel-cobalt i ke ana ʻana, nā mea kani, nā ʻāpana kaʻa, nā leo kiʻekiʻe, nā mea kaua a me nā aerospace a me nā kahua ʻē aʻe. ʻO Sintered alumini nickel cobalt he kūpono ia no ka hana ʻana i nā huahana paʻakikī, māmā, lahilahi, liʻiliʻi, i hoʻohana nui ʻia i nā kamaʻilio uila, nā kīʻaha magnet mau, nā hoʻololi magnetoelectric a me nā ʻano like ʻole. nā kiʻi kīkā uila, microphones, sensor leo, nā paipu nalu hele, (cowmagnet) a pēlā aku. Hoʻohana lākou a pau i nā magnet alumini-nickel-cobalt. Akā i kēia manawa, nui nā huahana e hoʻololi nei i ka hoʻohana ʻana i nā mea magnet honua laha, no ka mea hiki i kēia ʻano mea ke hāʻawi i ka Br ikaika a me ka BHmax kiʻekiʻe, e ʻae ana i ka nui o ka huahana liʻiliʻi.
