Ua ʻike anei ʻoe i ka ʻokoʻa ma waena o nā pā uwea alumini a me nā pā uwea kila kila?

◉  Nā pā uwea aluminia mekila kohu ʻolenā pā uwea ʻO nā mea ʻelua i hoʻohana pinepine ʻia i kā mākou huahana pā uwea. Eia kekahi, he laumania loa nā pā uwea alumini a me ke kila kila, he nani ko lākou helehelena, a makemake nui ʻia e nā mea kūʻai aku he nui, ʻike ʻoe i ka ʻokoʻa ma waena o lākou me nā kikoʻī?

ʻO ka mea mua, hoʻohui ʻia nā mea hoʻohuihui ʻē aʻe i ka alumini alloy, e hoʻomaikaʻi i ka ikaika o ka alumini maka, ka paʻakikī a me nā waiwai mechanical ʻē aʻe. ʻO ke ʻano kikoʻī, loaʻa i ka alumini alloy nā ʻano penei: māmā, plasticity, pale i ka corrosion, conductivity uila maikaʻi a hiki ke hana hou ʻia.

ʻO ke kila kila kila e pili ana i ka chromium content o 10.5% a ʻoi aku paha o ke kila, loaʻa iā ia nā hiʻohiʻona koʻikoʻi: kūpaʻa ikaika i ka pala, hana wela kiʻekiʻe maikaʻi, ʻili laumania maʻalahi e hoʻomaʻemaʻe a mālama, a he nani a lokomaikaʻi hoʻi ke ʻano.

◉Eia ka wehewehe kikoʻī o ko lākou ʻokoʻa.

1. Ikaika a me ka paʻakikī: ʻoi aku ka ikaika a me ka paʻakikī o ke kila kila ma mua o ka alumini metala, ʻo ia hoʻi ma muli o kona nui o ka chromium.

2. Ka nui o ka paʻa: ʻo ka nui o ka alumini alumini he 1/3 wale nō o ke kila kila, he mea māmā ia.

3. Hana ʻana: ʻoi aku ka maikaʻi o ka plasticity alumini me ka alumini, maʻalahi ke hana i nā ʻano hana like ʻole, ʻoiai ʻoi aku ka paʻakikī o ke kila kila, ʻoi aku ka paʻakikī o ka hana ʻana.

4. Ke kūpaʻa wela kiʻekiʻe: ʻoi aku ka maikaʻi o ke kila kila ma mua o ka alumini metala, hiki ke hoʻohana ʻia no nā hanana wela kiʻekiʻe 600°C.

5. Ke kūpaʻa ʻana i ka pala: loaʻa i nā mea ʻelua ke kūpaʻa maikaʻi i ka pala, akā ʻoi aku ka mana o ke kila kila.

6. Kumukūʻai: ʻoi aku ka haʻahaʻa o ke kumukūʻai me ka alumini metala, a ʻoi aku ke kiʻekiʻe o ke kumukūʻai me ke kila kila.

◉No laila, pono mākou e hoʻohana i nā koi kikoʻī o ka manawa i ke koho ʻana i nā mea pono no nā pā uwea ʻelua. Ma ke ʻano laulā, makemake nui ʻia ka alumini me nā mea māmā; makemake ʻia ke kūpaʻa i ka pala, makemake ʻia ke kila kila ikaika kiʻekiʻe; hiki iā ʻoe ke koho i ka alumini me nā mea i hoʻohana ʻia no ke kumukūʻai.
