ʻO Brass kahi huila binary i haku ʻia me ke keleawe a me ka zinc i hana ʻia no nā millennia a ua waiwai ʻia no kona hiki ke hana, paʻakikī, pale ʻana i ka corrosion, a me ka helehelena nani.
Hāʻawi ʻo Jindalai (Shandong) Steel Group Co., Ltd. i nā ʻano huahana keleawe like ʻole i ka nui a me ka nui e hoʻokō i nā pono o kēlā me kēia papahana.
1. Na waiwai
● ʻAno Alloy: Binary
● Maʻiʻo: Copper & Zinc
● Māmā: 8.3-8.7 g/cm3
● Lae hehee: 1652-1724 °F (900-940 °C)
● Ka Paʻakikī o Moh: 3-4
2. Na ano
ʻO nā waiwai kūpono o nā keleawe like ʻole e pili ana i ka haku ʻana o ke keleawe keleawe, ʻoi aku ka nui o ka ratio copper-zinc.Ma keʻano laulā, mahalo ʻia nā keleawe āpau no ko lākou machinability a i ʻole ka maʻalahi o ka hana ʻana i ka metala i nā ʻano a me nā ʻano i makemake ʻia me ka mālama ʻana i ka ikaika kiʻekiʻe.
ʻOiai aia nā ʻokoʻa ma waena o nā keleawe me nā mea zinc kiʻekiʻe a haʻahaʻa hoʻi, ua manaʻo ʻia nā keleawe āpau i hiki ke maʻalahi a me ka ductile (ʻoi aku ka nui o nā keleawe zinc haʻahaʻa).Ma muli o kona wahi heheʻe haʻahaʻa, hiki ke hoʻolei ʻia ke keleawe me ka maʻalahi.Eia nō naʻe, no ka hoʻolei ʻana, ʻoi aku ka nui o ka zinc maʻamau.
ʻO nā keleawe me ka haʻahaʻa o ka zinc maʻalahi hiki ke hana maʻamau, welded a brazed.ʻO ka ʻike keleawe kiʻekiʻe e hiki ai i ka metala ke hana i kahi papa pale oxide (patina) ma luna o kona ʻili e kiaʻi ai i ka ʻino hou aʻe, kahi waiwai nui i nā noi e hōʻike i ka metala i ka makū a me ka wā.
Loaʻa i ka metala ka wela a me ka conductivity uila (hiki i kāna conductivity uila mai 23% a 44% o ke keleawe maʻemaʻe), a ʻaʻahu a pale ʻia.E like me ke keleawe, ua hopena kona mau waiwai bacteriostatic i kona hoʻohana ʻana i nā hale ʻauʻau a me nā keʻena mālama olakino.
Ua manaʻo ʻia ʻo Brass he haʻahaʻa haʻahaʻa a me ka mea hao ʻole, ʻoiai ua hoʻohana ʻia kāna mau mea kani i nā mea kani 'brass band'.Hoʻohanohano ka poʻe kiʻi a me nā mea kālai kiʻi i nā waiwai nani o ka metala, no ka mea hiki ke hana ʻia i nā kala like ʻole, mai ka ʻulaʻula hohonu a i ka melemele gula.
3. Nā noi
ʻO nā waiwai waiwai o Brass a me ka maʻalahi o ka hana ʻana ua lilo ia i hoʻokahi o nā mea hoʻohana nui loa.He hana koʻikoʻi ka hōʻuluʻulu ʻana i kahi papa inoa piha o nā noi keleawe a pau, akā no ka loaʻa ʻana o ka manaʻo o nā ʻoihana a me nā ʻano huahana i loaʻa ai ke keleawe hiki iā mākou ke hoʻokaʻawale a hōʻuluʻulu i kekahi mau hoʻohana hope e pili ana i ka pae o ke keleawe i hoʻohana ʻia:
● Ke keleawe ʻoki manuahi (e laʻa me C38500 a i ʻole 60/40 keleawe):
● Nati, bolts, ʻāpana wili
● Nā ʻōkuhi
● Mokulele
● Paʻi
● Nā mea hoʻokomo
4. Moolelo
Ua hana ʻia nā ʻāpana keleawe-zinc i ka hoʻomaka ʻana o ke kenekulia 5 BC ma Kina a ua hoʻohana nui ʻia ma waena o Asia e ka 2nd a me ke kenekulia 3 BC.ʻO kēia mau ʻāpana metala hoʻonaninani, hiki ke kapa ʻia ʻo ia nā 'alulu kūlohelohe,' no ka mea, ʻaʻohe mea hōʻike i kā lākou mea hana i hoʻohui i ke keleawe a me ka zinc.Akā, ua hoʻoheheʻe ʻia nā mea hoʻoheheʻe ʻia mai ka zinc-rich copper ores, e hana ana i nā metala like me ke keleawe.
Hōʻike nā palapala Helene a me Roma i ka hana ʻana o nā mea hoʻohui e like me ke keleawe o kēia wā, me ka hoʻohana ʻana i ke keleawe a me ka zinc oxide-rich ore i kapa ʻia ʻo calamine, i hana ʻia ma kahi o ke kenekulia 1 BC. ipu me ka lepo smithsonite (a i ʻole calamine) oka.
Ma nā wela kiʻekiʻe, huli ka zinc i loko o ia ʻano i ka mahu a komo i ke keleawe, a laila e hana ana i ke keleawe maʻemaʻe me 17-30% zinc content.Ua hoʻohana ʻia kēia ʻano hana keleawe no kahi kokoke i 2000 mau makahiki a hiki i ka hoʻomaka ʻana o ke kenekulia 19.ʻAʻole i liʻuliʻu ma hope o ka ʻike ʻana o ka poʻe Roma i ka hana ʻana i ke keleawe, ua hoʻohana ʻia ka huila no ke kālā kālā ma nā wahi o Turkey i kēia manawa.Ua laha koke keia i ke aupuni Roma.
5. Nā ʻano
ʻO 'Brass' kahi huaʻōlelo maʻamau e pili ana i kahi ākea o nā ʻāpana keleawe-zinc.ʻOiaʻiʻo, aia ma luna o 60 mau ʻano keleawe like ʻole i kuhikuhi ʻia e EN (European Norm) Standards.Hiki i kēia mau mea hoʻohui ke loaʻa i nā ʻano hui like ʻole ma muli o nā waiwai i koi ʻia no kahi noi.
6. Hana ʻia
Hana pinepine ʻia ke keleawe mai nā ʻōpala keleawe a me nā ingots zinc.Koho ʻia ke keleawe ʻōpala ma muli o kona mau haumia, no ka mea, makemake ʻia kekahi mau mea ʻē aʻe i mea e hana ai i ka pae kūpono o ke keleawe e pono ai.
Ma muli o ka hoʻomaka ʻana o ka hoʻoheheʻe ʻana o ka zinc ma 1665°F (907°C), ma lalo o ka helu heheʻe keleawe 1981°F (1083°C), pono e hoʻoheheʻe mua ʻia ke keleawe.Ke hoʻoheheʻe ʻia, hoʻohui ʻia ka zinc ma kahi ratio kūpono no ka pae o ke keleawe i hana ʻia.ʻOiai ke hāʻawi ʻia nei kekahi ʻāpana no ka nalowale o ka zinc i ka vaporization.
I kēia manawa, hoʻohui ʻia nā metala ʻē aʻe, e like me ke alakaʻi, aluminika, silikoni a i ʻole arsenic, i ka hui ʻana e hana i ka alloy makemake.Ke hoʻomākaukau ʻia ka mea hoʻoheheʻe ʻia, ninini ʻia i loko o nā mole kahi e paʻa ai i loko o nā papa nui a i ʻole nā billet.ʻO nā pila - ʻo ka hapa nui o ke keleawe alpha-beta - hiki ke hana pololei ʻia i nā uea, nā paipu, a me nā paipu ma o ka extrusion wela, ʻo ia hoʻi ka hoʻokuʻu ʻana i ka metala wela ma o ka make, a i ʻole ka hana wela.
Inā ʻaʻole i hoʻokuʻu ʻia a hoʻopaʻa ʻia paha, hoʻomaʻamaʻa hou ʻia nā billet a hānai ʻia ma o nā wili kila (kahi hana i kapa ʻia ʻo ka ʻōwili wela).ʻO ka hopena he mau papa me ka mānoanoa o lalo o ka hapalua ʻīniha (<13mm).Ma hope o ka hoʻoluʻu ʻana, hānai ʻia ke keleawe ma o ka mīkini wili, a i ʻole scalper, nāna e ʻoki i kahi ʻāpana lahilahi mai ka metala i mea e wehe ai i nā hemahema o ka hoʻoheheʻe ʻana i luna a me ka oxide.
Ma lalo o ka lewa kinoea no ka pale ʻana i ka oxidization, ua hoʻomehana ʻia ka huila a ʻōwili hou ʻia, kahi kaʻina i ʻike ʻia he annealing ma mua o ka ʻōwili hou ʻia ʻana i nā mahana ʻoi aku ka maʻalili (cold rolling) i nā pepa ma kahi o 0.1 "(2.5mm) mānoanoa. Hoʻololi ke kaʻina ʻōwili anu ʻO ke ʻano o ka palaoa i loko o ke keleawe, e loaʻa ana i kahi metala ʻoi aku ka ikaika a ʻoi aku ka paʻakikī.
ʻO ka hope, ʻoki ʻia nā lau a ʻako ʻia e loaʻa ka laulā a me ka lōʻihi e pono ai.Hāʻawi ʻia nā lau a pau, hoʻolei ʻia, hana ʻia, a me nā mea keleawe i hoʻokuʻu ʻia i kahi ʻauʻau kemika, maʻamau, kahi i hana ʻia me ka waika hydrochloric a me ka sulfuric, e wehe i ka unahi keleawe keleawe ʻeleʻele a ʻeleʻele.
Jindalai inventory keleawe pepa a me nā wili i ka mānoanoa mai 0.05 a 50mm, a ma annealed, hapaha paakiki, hapalua paakiki, a piha paakiki.Loaʻa nā ʻano ʻokoʻa ʻē aʻe a me nā alloys.E hoʻouna i kāu nīnau a e hauʻoli mākou e nīnau iā ʻoe me ka ʻoihana.
