Ke kila kalaponaʻO kēia mea metala i kamaʻāina i nā mea a pau, ʻoi aku ka maʻamau i ka ʻoihana, ʻo kēia kila i ke ola he mau noi hoʻi, ma ka ʻōlelo holoʻokoʻa, ākea kāna kahua noi.
He nui nā pōmaikaʻi o ke kila kalapona, e like me ka ikaika kiʻekiʻe, ke kūpaʻa maikaʻi ʻana, ka plasticity ikaika, a me nā mea ʻē aʻe, no laila ua hoʻohana nui ʻia i ke kūkulu ʻana, automotive, aerospace a me nā māla ʻē aʻe.
ʻOiai nā mea maikaʻi o ke kila kalapona, loaʻa nō hoʻi nā hemahema, ua maʻalahi ʻo ia i ka rust, ʻano ʻōlelo, e ʻilihune ke kūpaʻa corrosion, no laila, i ka hoʻohana ʻana, pono mākou e hoʻolohe i ka mālama ʻana a me nā ana anti-corrosion.
Ke kila kalaponaʻO ka hao a me ke kalapona ka hapa nui o ke kalapona. Wahi a ka ʻike o ke kalapona a me ka hoʻohui ʻana o nā mea ʻē aʻe, hiki ke hoʻokaʻawale ʻia nā ʻano o ke kila kalapona i nā ʻano like ʻole, maʻamau i hoʻokaʻawale ʻia i ke kila kalapona haʻahaʻa, ke kila kalapona medium, ke kila kalapona kiʻekiʻe a me ke kila kila a me nā ʻano ʻē aʻe.
ʻO ke kila kila ka mea maikaʻi loa, ʻo kāna kahua noi ʻaʻole wale ia ma luna o nā mahina ʻē aʻe, akā i ka ʻoihana hana kaʻa, hoʻohana pinepine ʻia ke kila kalapona i ka hana ʻana i nā ʻāpana mīkini, huila, a me nā mea ʻē aʻe, i hiki ai ke hoʻomaikaʻi i kona pale ʻana a me ke ola lawelawe.
Eia kekahi, he maikaʻi ka weldability a me ka machinability. Hiki ke hana ʻia ke kila kalapona e ka welding, ke anu anuanu, ka wela wela a me nā ʻano ʻē aʻe e hoʻokō ai i nā koi kaʻina hana like ʻole, e like me kekahi mau ʻāpana a me nā ʻāpana like ʻole i kēlā me kēia lā, aerospace aircraft fuselage, nā ʻēheu a me nā ʻāpana ʻē aʻe hiki ke hana ʻia, i ka ʻoihana hana pū kekahi i kona wahi.

I kēia lā, nui nā mea hana ma ka mākeke i ke kila kalapona i kēia mea, hoʻopuka kēlā me kēia mea hana i ke kalapona kila ka maikaʻi, pehea mākou e ʻike ai i ka maikaʻi o ke kila kalapona i kēia mea e koho ai?
1. ʻIke mea waiwai: ʻo ke kila kalapona kiʻekiʻe ka mea maʻamau i kahi ʻike mea pono, e like me ka helu maʻamau, ka papa, a me nā mea ʻē aʻe.
2. Ka maikaʻi o ka hiʻohiʻona: Hiki iā ʻoe ke hele i ka hale hana e nānā i ke ʻano o ke kila kalapona ma ka pūnaewele, me ka palahalaha ʻole o ka ʻili, ʻaʻohe māwae maopopo, pores, inclusions a me nā hemahema ʻē aʻe. Pono ka ʻili kila kalapona kiʻekiʻe, ʻaʻohe hemahema.
3. Pono pono: Ke ana i ka pono o ke kalapona kalapona, me ka lōʻihi, ka laulā, ka mānoanoa, a me nā mea ʻē aʻe.
