HOOLAHA
Hoʻohana ʻia ka Aluminum i loko o nā hull, deckhouses, a me nā uhi paʻi o nā moku kalepa, a me nā mea lako, e like me nā alapiʻi, nā alapiʻi, nā ʻūhā, nā puka makani, a me nā puka. ʻO ka mea hoʻoikaika nui no ka hoʻohana ʻana i ka alumini ka mālama ʻana i ke kaumaha ma mua o ke kila.
ʻO nā pōmaikaʻi nui o ka mālama paona ma nā ʻano moku moana he hoʻonui i ka ukana, hoʻonui i ka hiki no nā mea hana, a hoʻemi i ka mana e pono ai. Me nā ʻano moku ʻē aʻe, ʻo ka pōmaikaʻi nui ka ʻae ʻana i ka hāʻawi maikaʻi ʻana i ke kaumaha, hoʻomaikaʻi i ke kūpaʻa a me ka hoʻolālā ʻana i ka hull.
ʻO ka 5xxx series alloys i hoʻohana ʻia no ka hapa nui o nā noi moana kalepa i loaʻa nā ikaika weld yield o 100 a 200 MPa. Mālama kēia mau alumini alumini-magnesium i ka weld ductility maikaʻi me ka ʻole o ka mālama ʻana i ka wela ma hope o ka weld, a hiki ke hana ʻia me nā ʻenehana a me nā mea hana maʻamau. ʻO ka weldable aluminika-magnesium-zinc alloys ke loaʻa nei ka manaʻo ma kēia kahua. ʻO ka pale ʻana i ka corrosion o ka 5xxx series alloys kekahi kumu nui i ke koho ʻana i ka alumini no nā noi kai. ʻO nā ʻāpana 6xxx series, hoʻohana nui ʻia no nā waʻa leʻaleʻa, hōʻike i ka emi ʻana o 5 a 7% i nā hoʻokolohua like.
