Ma muli o kāna conductivity uila maikaʻi loa, ʻo ke keleawe he mea hoʻohana nui ʻia i nā noi uila.Loaʻa iā ia kekahi mau waiwai kino a me nā kemika e lilo ia i mea hoʻokele uila kūpono.
ʻO ka mua, he kiʻekiʻe ka conductivity uila ke keleawe.ʻO ka conductivity e pili ana i ka hiki o kahi mea ke lawe i ke au uila.Loaʻa i ke keleawe kekahi o ka conductivity uila kiʻekiʻe loa o nā metala āpau.ʻO kona conductivity i ka lumi wela ma kahi o 58.5 miliona Siemens no ka mika (S/m).ʻO kēia conductivity kiʻekiʻe ʻo ia ka mea hiki i ke keleawe ke lawe maikaʻi i ka uku a hōʻemi i ka nalowale o ka ikehu ma ke ʻano o ka wela.Hiki iā ia ke kahe maikaʻi o nā electrons, hiki ke hoʻoili i ka mana ma nā mamao lōʻihi me ka ʻole o ka nalowale o ka mana.
ʻO kekahi o nā kumu he conductive nui ke keleawe ʻo kona ʻano atomic.Hoʻokahi wale nō electron i loko o kona pūpū waho loa, i hoʻopaʻa ʻia i ka nucleus.Hāʻawi kēia ʻano i nā electrons e neʻe manuahi i loko o ke ʻano lattice o ke keleawe.Ke hoʻohana ʻia kahi kahua uila, hiki i kēia mau electrons manuahi ke neʻe maʻalahi ma o ka lattice, e lawe ana i kahi au uila me ka liʻiliʻi.
Eia kekahi, he haʻahaʻa ka resistivity o ke keleawe.ʻO ka pale ʻana e pili ana i ke kūpaʻa kūlohelohe o kahi mea i ke kahe o ke au uila.He 1.68 x 10^-8 ohm-mika (Ω·m) ka resistivity o ke keleawe ma ka lumi wela.ʻO kēia resistivity haʻahaʻa, ʻo ia ka mea e hāʻawi liʻiliʻi loa ke keleawe i ke kahe o nā electrons, e hōʻemi ana i ka nalowale o ka ikehu a me ka hana wela.He mea koʻikoʻi ka resistivity haʻahaʻa no nā noi e pili ana i nā koi kiʻekiʻe o kēia manawa, e like me ka lawe mana a me nā uea.
ʻO ka maikaʻi o ke kalaiwa uila ma muli o kāna mau mea wela.Loaʻa iā ia ka conductivity thermal kiʻekiʻe, ʻo ia hoʻi ke alakaʻi maikaʻi ʻana i ka wela.He mea maikaʻi loa kēia waiwai i nā noi uila no ka mea hiki i ke keleawe ke hoʻopau i ka wela i hana ʻia e ke kahe o ke au uila.ʻO ka hoʻoheheʻe wela kūpono e kōkua i ka mālama ʻana i ka paʻa a me ka hilinaʻi o nā ʻāpana uila, pale i ka overheating a me ka hōʻoia ʻana i kā lākou hana lōʻihi.
Eia kekahi, ʻo ke keleawe he metala ductile loa.ʻO ka Ductility e pili ana i ka hiki o kahi mea ke huki ʻia i loko o nā uwea lahilahi me ka ʻole o ka haki ʻana.ʻO ka ductility kiʻekiʻe o ke keleawe he mea kūpono ia no ka uea no ka mea hiki ke hana maʻalahi a hana ʻia i mau uea lahilahi a maʻalahi.Hiki ke hoʻokuʻu ʻia kēia mau uea i nā hoʻonohonoho paʻakikī, e hoʻolilo iā lākou i mea kūpono no nā ʻano uila like ʻole, me nā hale noho, ʻoihana a me nā hale ʻoihana.
Hōʻike ʻo Copper i ka pale corrosion maikaʻi.Ke hōʻike ʻia i ka ea, hana ia i kahi ʻāpana oxide pale e pale ai i ka corrosion a me ka degradation.He mea koʻikoʻi kēia ʻano i nā noi uila no ka mea e hōʻoia i ka hilinaʻi lōʻihi a me ka lōʻihi o nā conductors keleawe.ʻO ke kūpaʻa corrosion o Copper e hiki ai iā ia ke mālama i kona conductivity uila no ka manawa lōʻihi a i nā wahi paʻakikī.
ʻO kekahi mea maikaʻi o ke keleawe ma ke ʻano he conductor uila ʻo ia ka nui a me ka loaʻa.He mea nui ke keleawe i laha nui a puni ka honua.ʻO kēia hiki ke hoʻolilo iā ia i koho maikaʻi loa no nā noi uila no ka mea hiki ke loaʻa a maʻalahi hoʻi i ka hoʻohālikelike ʻia me nā metala high-conductivity ʻē aʻe.
I ka hōʻuluʻulu ʻana, he mea hoʻokele uila maikaʻi loa ke keleawe ma muli o kāna conductivity uila kiʻekiʻe, resistivity haʻahaʻa, nā waiwai wela, ductility, corrosion resistance, a me ka nui.ʻO kāna ʻano atomic kū hoʻokahi a me nā waiwai kino e hiki ai ke lawe pono i nā uku me ka liʻiliʻi o ka ikehu.ʻO ka hana uila ʻokoʻa o Copper e lilo ia i mea waiwai nui i nā noi uila he nui, mai ka lawe mana a me nā uea i nā ʻāpana uila a me nā kaapuni.
