ʻO ke keleawe me ka zinc no ka mea ʻo ka mea nui o kahui keleawe, me ka melemele nani, i ʻōlelo ʻia he keleawe. Kapa ʻia ʻo Copper zinc binary alloy he keleawe maʻamau a i ʻole keleawe maʻalahi. Ua kapa ʻia ke keleawe me ʻekolu yuan he keleawe kūikawā a i ʻole keleawe paʻakikī. ʻO nā ʻāpana keleawe i loaʻa akā he 36% zinc i haku ʻia me nā ʻoluʻolu paʻa a loaʻa ka hana anuanu maikaʻi. e like me ka laʻana, ʻo ke keleawe me 30% zinc ka mea maʻamau e hana i nā pahu pūpū, i kapa ʻia ʻo shell brass a i ʻole he kanahikukūmākolu keleawe. ʻO nā ʻāpana keleawe me ka zinc content ma waena o 36 a me 42% ka mea i haku ʻia a me nā hoʻonā paʻa, ʻo ia ka mea i hoʻohana nui ʻia he keleawe hexagonal me ka zinc content o 40%. i mea e hoʻonui ai i ka hana o ke keleawe maʻamau, hoʻohui pinepine ʻia nā mea ʻē aʻe, e like me ka aluminika, nickel, manganese, tin, silicon, lead a laila. Hiki i ka alumini ke hoʻomaikaʻi i ka ikaika, ka paʻakikī a me ke kūpaʻa ʻana o ke keleawe, akā e hoʻemi i ka plasticity, no laila kūpono ia i nā paipu condensing Marine a me nā ʻāpana ʻē aʻe. Hiki i ke kino ke hoʻoikaika i ka ikaika o ke keleawe a me ka pale ʻana i ka wai kai, no laila ua kapa ʻia ʻo Tobin bronze, hoʻohana ʻia no nā lako wela a me nā propellers. Hiki i ke kepau ke hoʻomaikaʻi i ka hana ʻoki ʻana o ke keleawe. Hoʻohana mau ʻia kēia keleawe ʻoki manuahi ma ke ʻano he ʻāpana uaki. Hoʻohana pinepine ʻia nā hoʻolei keleawe e hana i nā kiwi a me nā pono paipu.
ʻO Bronze ka mea i kapa mua ʻia i ke keleawe keleawe, ma hope o nā ʻāpana keleawe koe wale nō ke keleawe a me ke keleawe keʻokeʻo i kapa ʻia he keleawe, a ʻo ke keleawe ma mua o ka inoa o ka mea nui i hoʻohui ʻia. ʻO ke keleawe keleawe he hana hoʻolei maikaʻi, hana hoʻohaʻahaʻa friction a me nā waiwai mechanical, kūpono no ka hana ʻana i nā bearings, nā huila a laila ma luna. ʻO ke keleawe keleawe paha he mea lawe i hoʻohana nui ʻia i nā ʻenekini hou a me nā mīkini wili. He ikaika kiʻekiʻe ka paʻakai keleawe-base, ke kūpaʻa ʻaʻahu maikaʻi a me ke kūpaʻa corrosion. hoʻohana ʻia ia no ka hoʻolei ʻana i nā mea hoʻoheheʻe, nā ʻōpala a me nā propellers Marine me ka ukana kiʻekiʻe. ʻO ke keleawe a me ke keleawe phosphatic he mau palena elastic kiʻekiʻe a me ka conductivity uila maikaʻi, e kūpono iā lākou no ka hana ʻana i nā pūnāwai pololei a me nā mea tangency. Hoʻohana pū ʻia ke keleawe i ka hana ʻana i nā mea hana sparkless i hoʻohana ʻia i loko o nā mine lanahu a me nā mea lawe aila.
ʻO kahi hui keleawe me ka nickel no ka mea ʻo ka mea hoʻohui nui. Ua kapa ʻia ʻo Cu-ni binary alloy he keleawe keʻokeʻo maʻamau; Hoʻohui i ka manganese, ka hao, ka zinc, ka aluminika a me nā mea ʻē aʻe o ka hui keleawe keʻokeʻo i kapa ʻia he keleawe paʻakikī. Hoʻokaʻawale ʻia ke keleawe keʻokeʻo ʻoihana i ke keleawe keʻokeʻo a me ke keleawe keʻokeʻo uila ʻelua ʻāpana. Hōʻike ʻia ke ʻano o ke keleawe keʻokeʻo e nā waiwai mechanical maikaʻi a me ke kūpaʻa corrosion, kala nani. Hoʻohana nui ʻia ke keleawe keʻokeʻo i nā mīkini kikoʻī, nā mīkini kemika a me nā ʻāpana moana.
Loaʻa ka inoa o ke keleawe mai kona ʻulaʻula. ʻAʻole ia he keleawe maʻemaʻe, a i kekahi manawa he liʻiliʻi ka nui o nā mea deoxidation a i ʻole nā mea ʻē aʻe i hoʻohui ʻia e hoʻoikaika i ka lole a me ka hana, no laila ua helu ʻia ʻo ia ma ke ʻano he keleawe keleawe. kūlike me ka haku mele ʻana o nā mea hana keleawe Kina ua māhele pinepine ʻia i ʻehā mau ʻāpana: keleawe maʻamau, keleawe ʻole oxygen, keleawe deoxidized, keleawe kūikawā me ka liʻiliʻi o nā mea hoʻohui. ʻO ke keleawe ka lua wale nō i ke kālā i ka conductivity a me ka thermal conductivity, a ua hoʻohana nui ʻia i ka hui ʻana o nā lako uila a me nā mea hana wela. ʻO ke keleawe i loko o ka lewa, ka wai kai a me kekahi mau waikawa non-oxidizing, alkali, ka paʻakai paʻakai a me ka hoʻolaha ʻana o nā waikawa organik (acetic acid, citric acid), maikaʻi ke kūpaʻa corrosion, hoʻohana ʻia ma ka ʻoihana. Eia kekahi, ʻo ke keleawe ʻulaʻula ka weldability maikaʻi, ua hana ʻia i loko o kahi ʻano o nā huahana semi-finished a me nā huahana i hoʻopau ʻia e ka hana anu a me ka thermoplastic.
