ʻO ka huaʻōlelo keleawe e pili ana i ke keleawe zinc alloy, ua hoʻomaka ia i ka Ming Dynasty, kāna moʻolelo ma ka "Ming Hui Dian": "Jiajing, no ka laʻana, Tongbao kālā ʻeono miliona wen, ʻelua keleawe ahi he kanahākumamāhiku tausani 272 jin…… .
keleawe He hui keleawe me ka zinc ma ke ʻano he mea hoʻohui nui, me ka waihoʻoluʻu melemele maikaʻi, i kapa ʻia he keleawe.Copper - zinc binary alloy ua kapa ʻia he keleawe maʻamau a i ʻole keleawe maʻalahi.Ua kapa ʻia ke keleawe ʻoi aku ma mua o ʻekolu yuan he keleawe kūikawā a i ʻole keleawe paʻakikī.
Loaʻa i nā ʻāpana keleawe i loaʻa ka liʻiliʻi ma lalo o 36% zinc, e like me ke keleawe me 30% zinc e hoʻohana mau ʻia no ka hana ʻana i nā pahu pūpū, i kapa ʻia ʻo shell brass a i ʻole 733 keleawe.
ʻO nā ʻāpana keleawe i loaʻa ma waena o 36 a me 42% zinc, ʻo ia ka mea maʻamau i hoʻohana ʻia he 64 keleawe me 40% zinc.ʻO nā hōʻailona maʻamau ʻo Hpb59-1, CW617N, JISC3771 a me C37700 series.
I mea e hoʻomaikaʻi 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, etc. Hiki i ka alumini ke hoʻomaikaʻi i ka ikaika, paʻakikī a me ka pale ʻana o ke keleawe, akā e hoʻemi i ka plasticity.He kūpono ia no ka paipu condensation liner moana a me nā ʻāpana kūʻē corrosion.Hiki ke hoʻoikaika i ka ikaika o ke keleawe a me ka corrosion i ka wai kai, no laila ua kapa ʻia ʻo ia he keleawe moana, hoʻohana ʻia no nā lako wela a me nā propellers.Hiki i ke alakaʻi ke hoʻomaikaʻi i ka hana ʻoki ʻana o ke keleawe;Hoʻohana mau ʻia kēia ʻoki keleawe maʻalahi i nā kiwi a me nā paipu paipu.
Hōʻikeʻia ka CW617N e ka machinability maikaʻi, nā mea mechanical maikaʻi a me ka hiki ke pale i ke anu.ʻO ka hana puʻe wela, ka wili maʻalahi, ka brazing, ka paʻa maikaʻi i ka corrosion maʻamau.
Hoʻohana ʻia ʻo CW617N no ka hoʻoulu ʻana i ka wela a me ke kaomi ʻana i nā ʻāpana like ʻole, me ka plumbing a me nā mea maʻemaʻe, nā ʻāpana a me nā ʻāpana valve, nā ʻāpana kaʻa, nā valve air conditioning, nā mīkini mīkini, nā nati a me nā ʻāpana ʻē aʻe e koi ana i kahi kiʻekiʻe o ka mīkini pololei.
Hoʻopili ʻia kā mākou mau mea keleawe, nā ʻāpana pōpō a me nā kīʻaha, nā ʻāpana keleawe me ka European standard CW617N extruded copper rod, nona ka hana thermal forming maikaʻi, ke kūpaʻa corrosion maikaʻi a me ka papa hana kiʻekiʻe.Ma o ka CNC machining, loaʻa iā ia nā hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe a me ka ʻālohilohi.
