Amalungu obhedu

Inkcazelo emfutshane:

I-alloy ye-Brass yi-alloy yobhedu kunye ne-zinc, ngokomlinganiselo onokuthi utshintshe ukufezekisa iipropati ezahlukeneyo zoomatshini, zombane, kunye neekhemikhali.I-alloy ye-substitution: ii-athomu zamacandelo amabini anokuthi atshintshe enye kwenye ngaphakathi kwesakhiwo sekristale esifanayo.

Intshayelelo yamalungu engxubevange yobhedu

Ubhedu lufana nobhedu, enye ialloyi equlathe ubhedu esebenzisa inkonkxa endaweni ye-zinc.Zombini ubhedu kunye nobhedu zinokubandakanya imilinganiselo emincinci yoluhlu lwezinye izinto ezibandakanya i-arsenic, ilothe, i-phosphorus, i-aluminiyam, i-manganese, kunye nesilicon.Ngokwembali, umahluko phakathi kwezi ngxubevange zimbini ubungaguquguquki kwaye ucace gca, kwaye ukwenziwa kwangoku kwiimyuziyam kunye ne-archaeology kuya kunqanda omabini la magama ezinto zembali ngokuthanda "ingxubevange yobhedu".

I-Brass ide ibe yinto eyaziwayo yokuhlobisa ngenxa yokukhanya kwayo, ukubonakala kwegolide;isetyenziselwa ukutsalwa kwedrowa kunye namaqhosha ocango.Kwakhona sele isetyenziswe ngokubanzi ukwenza izixhobo ngenxa yeempawu ezifana nokuba neqondo eliphantsi lokunyibilika, ukusebenza okuphezulu (zombini ngezixhobo zezandla kunye noomatshini banamhlanje bokujika kunye nokugaya), ukuqina, kunye nombane kunye ne-thermal conductivity.

Ukusetyenziswa kwamalungu engxubevange yobhedu

I-alloy ye-Brass isasetyenziswa ngokuqhelekileyo kwizicelo apho ukuxhathisa kwe-corrosion kunye nokukhuhlana okuphantsi kuyadingeka, ezifana nezitshixo, iihenjisi, iigiya, iibheringi, ii-ambul casings, ii-zippers, i-plumbing, i-hose couplings, i-valve, kunye neeplagi zombane kunye neziseko.Isetyenziswa kakhulu kwizixhobo zomculo ezinje ngeempondo neentsimbi, kwaye ikwasetyenziswa njengendawo yobhedu ekwenzeni izacholo zesinxibo, ubucwebe befashoni, kunye nezinye izacholo zokulinganisa.Ukubunjwa kobhedu, ngokuqhelekileyo i-66% yobhedu kunye ne-34% ye-zinc, yenza ukuba ithathe indawo yezacholo ezenziwe ngobhedu, njengoko ibonisa ukuxhathisa okukhulu kwi-corrosion.I-Brass isoloko isetyenziswa kwiimeko apho kubalulekile ukuba iintlantsi zingabethelwa, ezifana nezixhobo kunye nezixhobo ezisetyenziswa kufuphi nezinto ezinokutsha okanye eziqhumayo.

Zonke iintlobo ze-alloy ye-Brass

Iklasi	Umlinganiselo ngokobunzima (%)		Amanqaku
Iklasi	Ubhedu	Zinc	Amanqaku
Iibrasi zeAlpha	> 65	<35	Iibrasi zeAlpha ziyabumbeka, zinokusetyenzwa zibandayo, kwaye zisetyenziselwa ukucinezela, ukubunjwa, okanye usetyenziso olufanayo.Ziqulethe isigaba esinye kuphela, kunye nesakhiwo sekristale ye-cubic ebusweni.Ngomlinganiselo wabo ophezulu wobhedu, ezi zobhedu zine-hue yegolide ngakumbi kunabanye.Isigaba se-alpha sisisombululo esiqinileyo se-zinc endaweni yobhedu.Isondele kwiipropathi zobhedu, yomelele, yomelele, kwaye kunzima ukuyitshintsha.Ukubunjwa okugqwesileyo kukunye ne-32% ye-zinc.Iibrasi ezibomvu ezimelana nokubola, ezine-15% ye-zinc okanye ngaphantsi, zilapha.
Iibrasi zeAlpha-beta	55–65	35–45	Kwakhona kuthiwaiibrasi ezimbini, ezi zilungele ukusebenza okushushu.Ziqulethe zombini izigaba ze-α kunye ne-β';i-β'-phase icwangciswe nge-cubic egxile kumzimba, kunye ne-athomu ye-zinc embindini weetyhubhu, kwaye inzima kwaye yomelele kuno-α.Iibrasi zeAlpha-beta zidla ngokusetyenzwa zishushu.Umlinganiselo ophezulu we-zinc uthetha ukuba ezi bras ziqaqambile kunealpha brasses.Kwi-45% ye-zinc i-alloy inamandla aphezulu.
Iibrasi zeBeta	50–55	45–50	Iibrasi zeBeta zinokusetyenzwa zishushu kuphela, kwaye ziqinile, zomelele, kwaye zilungele ukuphoswa.Umxholo ophezulu we-zinc-low-copper uthetha ukuba ezi zizinye zezona zinto ziqaqambileyo kwaye zincinci-zegolide kwiibrasi eziqhelekileyo.
Iibrasi zeGamma	33–39	61–67	Kukwakho ne-Ag-Zn kunye ne-Au-Zn ii-gamma brasses, Ag 30–50%, Au 41%.Isigaba se-gamma yi-cubic-lattice intermetallic compound, Cu.₅Zn₈.
Ubhedu olumhlophe	<50	> 50	Ezi brittle kakhulu ukuba zisetyenziswe ngokubanzi.Eli gama linokuthi libhekiselele kwiintlobo ezithile ze-nickel alloys yesilivere kunye ne-Cu-Zn-Sn alloys enemilinganiselo ephezulu (ngokuqhelekileyo i-40% +) ye-tin kunye / okanye i-zinc, kunye ne-zinc casting alloys ene-additives zobhedu.Ezi phantse azinambala omthubi kwaphela, kwaye endaweni yoko zinenkangeleko esilivere ngakumbi.
