Nzira yekuziva rudzi rwealloy yemhangura?
Mhangura chena, ndarira, mhangura tsvuku (inozivikanwawo se "red copper"), uye bhuronzi (blue-grey kana grey-yellow) inosiyaniswa nemuvara.Pakati pavo, mhangura chena nendarira zviri nyore kwazvo kusiyanisa;mhangura tsvuku imhangura yakachena (kusvibiswa <1%) uye bronze (zvimwe zvikamu zvealloy zvinenge 5%), izvo zvishoma zvakaoma kusiyanisa.Kana isina oxidized, ruvara rwemhangura tsvuku runopenya kupfuura yendarira, uye ndarira ine zvishoma cyan kana yero rima;mushure me oxidation, mhangura tsvuku inova yakasviba, uye bhuronzi ine turquoise (inokuvadza oxidation yemvura) kana chokoreti.
Kurongeka uye welding maitiro emhangura nemhangura alloys:
(1) Mhangura yakachena: Mhangura yakachena inowanzonzi mhangura tsvuku.Iine yakanaka conductivity yemagetsi, thermal conductivity uye corrosion resistance.Mhangura yakachena inomiririrwa nebhii +T}} (mhangura), yakadai seTl, T2, T3, nezvimwewo. Okisijeni yemukati yakaderera zvakanyanya, uye mhangura yakachena isina kupfuura 0.01% inonzi mhangura isina oxygen, inova inomiririrwa neTU (mhangura isina), yakadai seTU1, TU2, nezvimwe.
(2) Brass: Iyo alloy yemhangura ine zingi sechinhu chikuru chinosanganisa chinonzi ndarira.Brass inoshandisa +H;(yero) zvinoreva H80, H70, H68, nezvimwe.
(3) Bronze: Kare, alloy yemhangura nerata yainzi bronze, asi iye zvino mavheji emhangura asiri endarira anonzi bhuronzi.Inowanzo shandiswa tin bronze, aluminium bronze uye min bronze.Bronze inomiririrwa ne "Q" (cyan).
Mabatirwo emhangura nemhangura maaloyi emhangura ndeaya: ① yakaoma kusanganisa uye nyore kutsveyamisa;② nyore kugadzira anopisa makatsemuka;③ nyore kugadzira pores
Mhangura nemhangura alloy welding inonyanya kutora gasi welding, inert gasi yakadzivirirwa welding, yakadzika arc welding, brazing nedzimwe nzira.
Mhangura nemhangura alloys ane yakanaka yekupisa conductivity, saka kazhinji anofanirwa kuve akapiswa asati atungidzirwa, uye mutsara wakakura simba unofanirwa kushandiswa pakunama.Iyo hydrogen tungsten arc welding inotora DC yakanaka yekubatanidza.Mune gasi welding, murazvo usina kwawakarerekera kana murazvo usina simba wecarbonization unoshandiswa kumhangura, uye murazvo usina oxidizing unoshandiswa kundarira kudzivirira kubuda kwe zinc.
