ʻO ka pā kila ʻōwili wela kahi ʻano kila kaulana i hoʻohana nui ʻia i ka hana ʻana, ke kūkulu ʻana a me nā ʻoihana kaʻa.

Hanaʻia ia ma ke kauʻana i ke kila wela ma o nā pahu i nā mahana kiʻekiʻe, kahi e hoʻonui ai i kona lōʻihi, ikaika a me ka maikaʻi holoʻokoʻa. ʻO kekahi o nā pōmaikaʻi nui o ke kila ʻōwili wela ʻo ia kona versatility. Hoʻohana ʻia ia i nā ʻano hana like ʻole, mai ke kūkulu hale a me nā alahaka i ka hana ʻana i nā mīkini a me nā mea hana. ʻO kona ikaika a paʻa hoʻi e lilo ia i koho kaulana no ka hana ʻana i nā ʻāpana kaʻa. ʻO kekahi pōmaikaʻi o ke kila ʻōwili wela ʻo ia ka maikaʻi o ke kumukūʻai. ʻOi aku ka maikaʻi ma mua o nā ʻano kila ʻē aʻe, e like me ke kila ʻōwili anuanu, e lilo ia i koho maikaʻi no nā ʻoihana a me nā mea hana ma kahi kālā. He mea maʻalahi hoʻi ka hana ʻana i ke kila ʻōwili wela, ʻo ia hoʻi, hiki ke hana ʻia i nā mea nui me ka wikiwiki a me ka maikaʻi. He mea kūpono kēia no nā koi hana kiʻekiʻe. Ma keʻano o ka hana, uaʻikeʻia nā pale kila wela e ka paʻakikī, ka ductility, a me ka machinability. ʻO kēia mau waiwai e maʻalahi ka hana ʻana a hana ʻia i nā huahana i makemake ʻia, inā he pepa maʻalahi a i ʻole kahi ʻāpana mīkini paʻakikī.

Eia naʻe, ʻaʻole me ka palena ʻole o nā pā kila wela. ʻAʻole maʻalahi kona hoʻopau ʻana i ka ʻili e like me ke kila ʻōwili anuanu, no laila ʻaʻole kūpono ia no kekahi mau noi e pono ai ka hoʻopau ʻoi aku ka maikaʻi. ʻOi aku ka maʻalahi o ka corrosion a me ka oxidation, hiki ke hoʻoponopono ʻia me ka uhi kūpono a me ka mālama ʻana.

I ka hopena, he mea maʻalahi a me ke kumu kūʻai i loaʻa nā noi ākea i nā ʻoihana like ʻole. ʻO kona ikaika, lōʻihi a me ka machinability e kūpono ia no nā kaʻina hana he nui a hiki ke hana ʻia i nā puke kiʻekiʻe me ka wikiwiki a me ka maikaʻi.
