Sezvinoratidzwa nezita racho,ndarira yegungwais a alloy yemhangura inokodzera zviitiko zvegungwa. Izvo zvikamu zvikuru zvemhangura (Cu), zinc (Zn) uye tini (Sn). Alloy iyi inonziwo tin brass. Kuwedzerwa kwetini kunogona kunyatso kuvharidzira dezincification yendarira uye kunatsiridza huturu kuramba.
Munharaunda yegungwa, firimu rakatetepa uye rakaonda rinodzivirira richaita pamusoro pemhangura alloy, iyo inonyanya kuumbwa nemhangura uye tin oxides uye mamwe mamunyu akaoma. Iri denga rekudzivirira rinogona kudzivirira zvinobudirira mvura yegungwa kuti isaora mukati meiyo alloy uye inonoke kukora. Kuenzaniswa nendarira yakajairika, mwero wekuora kwendarira yegungwa unogona kudzikiswa kakawanda.
Common naval copper alloys inosanganisiraC44300(HSn70-1/T45000), iyo ine zvinotevera kuumbwa:
Mhangura (Cu): 69.0% - 71.0%
Zinc (Zn): Balance
Tini (Sn): 0.8% - 1.3%
Arsenic (As): 0.03% - 0.06%
Zvimwe zvinosanganiswa zvinhu: ≤0.3%
Arsenic inogona kuvharidzira dezincification corrosion uye inowedzera kunatsiridza kuputika kwekudzivirira kwealloy.C44300 ine maitiro akanaka emagetsi uye inoshandiswa kugadzira kupisa kunopisa uye conduits zvinosangana nezvinwiwa zvinopisa. Inonyanya kushandiswa mukati menyika inopisa simba zvidyarwa kugadzira yakakwirira-simba, corrosion-resistant heat exchanger condenser tubes. Zvidzidzo zvenguva pfupi yapfuura zvakaratidza kuti kuwedzera kuteedzera huwandu hweboron, nickel uye zvimwe zvinhu kuC44300 zvinogona kuvandudza kusimba kwekuora. C44300 ine tsika yekusimbisa ngura kutsemuka, uye mapaipi anotonhora-akagadziridzwa anofanirwa kuve pasi pekunetseka kudzika-tembiricha annealing. C44300 inowanzoita kuputika panguva yekupisa kupisa, uye zvinyorwa zvetsvina zvinofanira kunyatsodzorwa.
C46400(HSn62-1/T46300) zvakare indarira yegungwa ine yakaderera mhangura yemukati. Zvikamu zvaro zvikuru ndezvizvi:
Cu: 61-63%
Zn: 35.4-38.3%
Sn: 0.7-1.1%
Fe: ≤0.1%
Pb: ≤0.1%
C46400 inotonhora brittle panguva yekushanda inotonhora uye inokodzera chete kupisa kupisa. Iine machinability yakanaka uye iri nyore kupinza uye kubhuroka, asi ine katsika kekuita ngura uye kutsemuka (seasonal crack). C46400 tin brass inoshandiswa muindasitiri yekuvaka ngarava kugadzira zvikamu zvinosangana nemvura yegungwa, peturu, nezvimwe.
Nekuda kwemusiyano mudiki pakati pezviyero, seChinese brass strip / brass tsvimbo/mutengesi weplate yendarira, tinowanzo shandisa HSn62-1 kutsiva C46400/C46200/C4621. Mhangura yemhangura yeC46200 yakakwirira zvishoma.
C48500(QSn4-3) indarira yemvura inotungamira. Iyo inotungamira yemukati yakakwira kupfuura mamakisi maviri ataurwa pamusoro apa. Zvikamu zvaro zvikuru ndezvizvi:
Mhangura (Cu): 59.0% ~ 62.0%
Kutungamira (Pb): 1.3% ~ 2.2%
Simbi (Fe): ≤0.10%
· Tin (Sn): 0.5%~1.0%
Zinc (Zn): Balance
Phosphorus (P): 0.02%~0.10%
Iine elasticity yakanaka, kupfeka kuramba uye anti-magnetism. Inokodzera kushandiswa kwekumanikidza munzvimbo dzinotonhora uye dzinopisa. Zviri nyore kuisa weld uye braze. Iine machinability yakanaka uye yakanaka corrosion resistance mumhepo, mvura yakachena uye mvura yegungwa. Inowanzoshandiswa mumhando dzakasiyana-siyana elastic, pombi fittings, makemikari emidziyo, kupfeka-resistant zvikamu uye anti-magnetic zvikamu.
