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

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

Eia nō naʻe, ʻaʻole nele nā ​​​​papa kila i ʻōwili wela ʻia. ʻAʻole laumania kona ʻili e like me ke kila i ʻōwili anu ʻia, e lilo ia i mea kūpono ʻole no kekahi mau noi e pono ai kahi ʻoi aku ka maikaʻi. ʻOi aku ka maʻalahi o ka pala a me ka oxidation, hiki ke hoʻoponopono ʻia me ka uhi pono a me ka mālama ʻana.

I ka hopena, he mea maʻalahi a kūpono hoʻi ke kumukūʻai o ka pepa kila i ʻōwili wela ʻia e loaʻa ana nā noi ākea ma nā ʻoihana like ʻole. ʻO kona ikaika, kūpaʻa a me ka machinability e kūpono ia no nā kaʻina hana he nui a hiki ke hana ʻia i nā nui he nui me ka wikiwiki a me ka maikaʻi.
