Hoʻohana nui ʻia nā hoʻoheheʻe keleawe ma ka pā valve a me ka pā ma muli o ka hana maikaʻi o nā mea keleawe. Ma RMC Foundry, hana nui mākou i kahoolei keleawee ka hoolei one omaomao, hoolei one uhi resin,hoʻolei kālāa no nā hoʻolei keleawe nui, lawe pū mākou i ke kaʻina hana hoʻoheheʻe a me ka hoʻoheheʻe ʻana. ʻO ka maʻamau, ʻo nā mea hoʻolei keleawe i hana ʻia e ka hoʻolei ʻana i ke one ʻo ia ka ʻāpana nui i kā mākou foundry.
ʻO ke keleawe keleawe me ka zinc ma ke ʻano he mea hoʻohui nui i kapa ʻia he keleawe. Ua kapa ʻia ʻo Copper-zinc binary alloy he keleawe maʻamau, a ʻo ternary, quaternary a i ʻole multi-element keleawe i hana ʻia ma ka hoʻohui ʻana i kahi liʻiliʻi o nā mea ʻē aʻe ma ke kumu o ke keleawe-zinc alloy ua kapa ʻia he keleawe kūikawā. Hoʻohana ʻia ke keleawe hoʻolei e hana i ke keleawe no ka hoʻolei ʻana. Hoʻohana nui ʻia nā hoʻoheheʻe keleawe i ka mīkini hana, valve a me nā pumps, nā moku, nā mokulele, nā kaʻa, ke kūkulu ʻana a me nā ʻoihana ʻoihana ʻē aʻe, e noho ana i kahi kaumaha i nā mea metala koʻikoʻi non-ferrous, e hana ana i nā moʻo keleawe.
Ke hoʻohālikelike ʻia me ke keleawe a me ke keleawe, nui loa ka solubility paʻa o ka zinc i ke keleawe. Ma lalo o ka equilibrium mahana maʻamau, hiki ke hoʻoheheʻe ʻia ma kahi o 37% o ka zinc i ke keleawe, a ma kahi o 30% o ka zinc hiki ke hoʻoheheʻe ʻia ma ke ʻano hoʻoheheʻe ʻia, ʻoiai ke keleawe keleawe I ka mokuʻāina as-cast, ka hapa nui o ka solubility paʻa o ka tin. i ke keleawe he 5% a 6% wale nō. ʻO ka hapa nui o ka solubility paʻa o ke keleawe alumini i ke keleawe he 7% a 8% wale nō. No laila, loaʻa i ka zinc kahi hopena hoʻoikaika paʻa paʻa i ke keleawe. I ka manawa like, hiki ke hoʻoheheʻe ʻia ka hapa nui o nā mea hoʻohui i ke keleawe i nā degere like ʻole , E hoʻomaikaʻi hou i kona mau ʻano mechanical, no laila ke keleawe, ʻoi aku ka nui o ke keleawe kūikawā i nā ʻano o ka ikaika kiʻekiʻe. ʻOi aku ka haʻahaʻa o ke kumu kūʻai o ka zinc ma mua o ka aluminika, ke keleawe, a me ka tin, a he waiwai nui ia. ʻOi aku ka nui o ka zinc i hoʻohui ʻia i ke keleawe, no laila ʻoi aku ke kumukūʻai o ke keleawe ma mua o ke keleawe keleawe a me ke keleawe alumini. Loaʻa i ke keleawe kahi pae wela solidification liʻiliʻi, ka wai maikaʻi, a me ka hoʻoheheʻe kūpono.
Ma muli o ke keleawe i nā hiʻohiʻona i ʻōlelo ʻia ma luna o ka ikaika kiʻekiʻe, ke kumukūʻai haʻahaʻa a me ka hana hoʻoheheʻe maikaʻi ʻana, ʻoi aku ka nui o nā ʻano like ʻole o ke keleawe, ʻoi aku ka nui o ka hoʻopuka a me ka hoʻohana ākea ma mua o ke keleawe keleawe a me ke keleawe alumini i nā ʻāpana keleawe. Eia nō naʻe, ʻaʻole maikaʻi ka maikaʻi o ka pale ʻana a me ke kūpaʻa ʻana o ke keleawe e like me ke keleawe, ʻoi aku ka haʻahaʻa o ka pale ʻana a me ke kūpaʻa ʻana o ke keleawe maʻamau. Ke hoʻohui wale ʻia kekahi mau mea hoʻohui e hana i nā keleawe kūikawā like ʻole, ua hoʻomaikaʻi a hoʻomaikaʻi ʻia kona kūpaʻa ʻaʻahu a me ka hana corrosion.
ʻO nā hoʻoheheʻe keleawe a me nā hoʻoheheʻe keleawe he mau mea hoʻoheheʻe keleawe i hiki ke hoʻolei ʻia e ka hoʻolei ʻana i ke one a me nā kaʻina hoʻoheheʻe kālā. ʻO ke keleawe he huila i haku ʻia me ke keleawe a me ka zinc. ʻO ke keleawe i haku ʻia me ke keleawe a me ka zinc ua kapa ʻia he keleawe maʻamau. Inā he ʻano huila like ʻole i haku ʻia ma mua o ʻelua mau mea, ua kapa ʻia ʻo ia he keleawe kūikawā. He keleawe keleawe me ka zinc ka mea nui. I ka piʻi ʻana o ka zinc content, piʻi nui ka ikaika a me ka plasticity o ka alloy, akā e emi nui nā waiwai mechanical ma hope o 47%, no laila ʻoi aku ka liʻiliʻi o ka zinc ma mua o 47%. Ma waho aʻe o ka zinc, loaʻa pinepine ka keleawe hoʻolei i nā mea hoʻohui e like me ke silika, manganese, aluminika, a me ke alakaʻi.
