Inoa Huahana:
Uea Alloy Sila Aniani 4J28 | Uea Alloy Fe-Ni | Mea Magnetika Palupalu

Mea Hana:
4J28 (Fe-Ni Alloy, Kovar-ʻano Glass-Sealing Alloy)

Nā kikoʻī:
Loaʻa i nā anawaena like ʻole (0.02 mm a 3.0 mm), hiki ke hoʻopilikino ʻia nā lōʻihi

Nā noi:
Ke sila ʻana o ke aniani-a-metala, nā paipu uila, nā mea ʻike, nā ʻāpana vacuum, a me nā mea uila kikoʻī ʻē aʻe

Ka Hana ʻIli:
ʻIli ʻālohilohi, ʻaʻohe oxide, annealed a i ʻole ke anu

Pūʻolo:
ʻAno Coil/Spool, ʻōwili palaki, ʻeke i hoʻopaʻa ʻia me ka vacuum a i ʻole ka ʻōpala i hoʻopilikino ʻia ma ke noi

Wehewehe Huahana:

4J28 alloy wire, i ʻike ʻia hoʻi ʻoUea hui Fe-Ni, he mea hoʻopaʻa aniani a me ka magnetic palupalu pololei. Me kahi ʻano i haku ʻia me ka hao a me kahi 28% nickel, hāʻawi ia i ka hoʻonui wela kūikawā me ke aniani borosilicate, e hoʻohana nui ʻia ana i ka hoʻopili uila a me nā noi sila aniani-a-metala.

uea 4J28hōʻike i nā waiwai sila maikaʻi loa, ka hana magnetic paʻa, a me nā ʻano mechanical hilinaʻi. Hoʻohana nui ʻia ia i nā paipu uila, ka hoʻopili hermetic, nā hale semiconductor, a me nā ʻāpana aerospace a me nā pūʻali koa hilinaʻi kiʻekiʻe.

Nā Hiʻohiʻona:

• Ke Sila Aniani-a-Metala Maikaʻi Loa: Kūpono ka hoʻonui wela me ke aniani borosilicate no nā sila paʻa a hermetic

• Nā Waiwai Magnetic Maikaʻi: Kūpono no nā noi magnetic palupalu a me ka pane magnetic paʻa

• Kiʻekiʻe Ana Kiʻekiʻe: Loaʻa i nā anawaena maikaʻi loa, i huki ʻia me ka pololei no nā ʻāpana uila koʻikoʻi

• Ke kū'ē'ē'ana i ka Oxidation: ʻIli mālamalama, ʻaʻohe oxidation, kūpono no ka vacuum a me ka sila hilinaʻi kiʻekiʻe

• Hiki ke hoʻopilikino ʻia: Hiki ke hoʻopilikino ʻia nā ana, ka ʻōpala, a me nā kūlana o ka ʻili i nā pono kikoʻī o ka mea kūʻai aku

Nā noi:

• Nā paipu uila a me nā mea hana vacuum

• Nā relays a me nā mea ʻike i hoʻopaʻa ʻia i ke aniani-a-metala

• Nā pūʻolo semiconductor a me nā pūʻolo hermetic

• Nā ʻāpana uila mokulele a me nā ʻāpana koa

• ʻO nā ʻāpana optical a me ka microwave e pono ai ka hoʻohālikelike ʻana o ka hoʻonui wela pololei
