Pepa Metala
He mea metala maʻamau, hana maʻamau i ke ʻano like me ka lau, he nui nā mea hoʻohana, me ka hana ʻana i nā ʻāpana, nā uhi, nā ipu, a me nā mea metala ʻē aʻe. Hana ʻia ka lau metala me nā mea metala e like me ke aluminika, ke kila, ke keleawe, ka zinc, nickel, a me ka titanium, a ma waena o 0.015 iniha (0.4 mm) a me 0.25 iniha (6.35 mm) ka mānoanoa.
He nui nā hiʻohiʻona kūʻokoʻa o ka lau metala:
Ka ikaika a me ka lōʻihi: Hiki i ka lau metala ke hāʻawi i ka ikaika kūpono a me ka lōʻihi e hoʻokō i nā koi o nā noi like ʻole. ʻOiai ʻo kona mānoanoa lahilahi, hiki ke loaʻa i ka metala metala ke kūpaʻa maikaʻi, tensile a me ka corrosion ma hope o ka hoʻoponopono pono ʻana a me ka mālama ʻana, a kūpono no ka hoʻohana ʻana ma lalo o nā kūlana kaiapuni.
Plasticity a me ka formability: He maikaʻi ka palaki a me ke ʻano o ka metala, a hiki ke hana ʻia i nā ʻano like ʻole a me nā nui ma o nā kaʻina hana metala (e like me ke kuʻi ʻana, ke kuʻi ʻana, ke kuʻi ʻana, ka welding, a me nā mea ʻē aʻe) e hoʻokō i nā pono ʻenehana a me ka hoʻolālā. ʻO kēia maʻalahi ka mea i kūpono i ka lau metala no ka hana ʻana i nā ʻāpana paʻakikī a me nā ʻāpana maʻamau. Māmā: Ma muli o ka haʻahaʻa haʻahaʻa haʻahaʻa o ka pepa metala, ʻoi aku ka māmā o ke kaumaha. ʻO kēia ka mea e hiki ai i nā ʻāpana i hana ʻia me ka metala e hōʻemi pono i ke kaumaha holoʻokoʻa ʻoiai e hōʻoiaʻiʻo ana i ka ikaika a me ka lōʻihi, kahi kūpono i ka hōʻemi ʻana i nā kumukūʻai kaʻa a me ka hoʻomaikaʻi ʻana i ka hoʻohana pono.
ʻO ka hilinaʻi a me ke kūpaʻa: Hiki i ka lau metala ke hoʻokō i ka pololei kiʻekiʻe a me ke kūlike i ka hana hana e hōʻoia i ka maikaʻi o ka huahana a me ka paʻa. He mea nui kēia no nā noi e koi ana i nā ana kikoʻī a me nā kūlana kiʻekiʻe, e like me ka aerospace, ka hana kaʻa, a me nā mea uila. Hiki ke uhi ʻia: Hiki ke mālama maʻalahi ʻia ka ʻili o ka lau metala, e like me ka pena spray, electroplating, galvanized, etc., e hoʻomaikaʻi i kāna hana o ka ʻili a me nā mea nani. Hoʻolilo kēia i ka metala pepa i mea kūpono no ka laulā o nā kala, nā hopena ʻili a me nā koi pale corrosion.
