Ipleyiti yobhedu yenkcenkceukubunjwa yintsimbi yobhedu ukuvelisa iicastings.Ukufakwa kweBronze kusetyenziswa kakhulu kwimveliso yoomatshini, iinqanawa, iimoto, ulwakhiwo kunye namanye amacandelo oshishino, ukwenza uthotho lobhedu oluphoswe kwizinto ezinzima zentsimbi.Ubhedu oluqhelekileyo olusetyenziswayo yipleyiti yobhedu yetin, ubhedu olulothe, isinyithi seMuntz kunye nobhedu lwe-aluminiyam.inani lokucutheka kwe-alloy ye-Cu-Sn lincinci kakhulu (ireyithi yokucutheka kwe-linear yi-1.45% ukuya kwi-1.5%), kwaye kulula ukubonelela ngee-castings eziyinkimbinkimbi kunye nemisebenzi yezandla kunye neepateni ezicacileyo ezifuna imilinganiselo echanekileyo.Kwi-bronze ye-tin engaguqukiyo, umxholo we-phosphorus uhlala uphezulu njenge-1.2%.I-Zinc inokuphucula i-fluidity ye-alloy kunye nokunciphisa ukuthambekela kokuhlukana kwe-tin bronze.I-Lead iphucula kakhulu ukuguga kunye nokukrazula ukuxhathisa kunye nokusebenza kwe-alloy.I-Cast tin bronze isetyenziswa njengeendawo ezigugileyo kunye nokumelana nomhlwa.I-Tin Phosphor Bronze: I-Phosphorus inokuba yi-deoxidizer efanelekileyo ye-alloys yobhedu, enokunyusa ukumanzi kwe-alloy, iphucule iteknoloji kunye neepropathi zomatshini ze-tin bronze, kodwa yandisa iqondo lokuhlukana.Umda wokunyibilika kwe-phosphorus kwi-Hebei tin bronze yi-0.15%, ukuba ubuninzi obugqithisileyo, iyakwenza i-α+δ+Cu3P ternary eutectic, indawo yokukhenkceza yi-628℃, kulula ukunika i-brittleness eshushu ngexesha lokuqengqeleka okushushu, ngoko ke ingasebenza kuphela kubanda.Ngoko ke, umxholo we-phosphorus kwi-bronze ye-tin ekhubazekileyo akufanele ibe ngaphezu kwe-0.5%, kwaye ngoko ke i-phosphorus kufuneka ibe yi-0.25% ngexesha lokusebenza okushushu.Ubhedu lwe-tin ene-phosphorus lunokuba yinto eyaziwayo e-elastic.Ngexesha lokucutshungulwa, kuyimfuneko ukulawula ubungakanani beenkozo phambi kokuba kubanda kusebenze kunye nokufunxa okubandayo emva kokulungiswa.Amandla, i-modulus ye-elasticity kunye namandla okudinwa kwezinto ezicolekileyo zingaphaya kwezinto ezinqabileyo, kodwa iplastiki iphantsi.Izinto ezibandayo zifakwe kubushushu bekofu obuyi-200-260 ℃ kangangeeyure ezi-1 ukuya kwezi-2, nto leyo ekhokelela ekubeni i-annealing kunye nesiphumo sokuqina, esinokuthi siphucule ngakumbi amandla, iplastiki, umda we-elastic kunye nemodyuli yokuqina kwentengiso, kunye nokwandisa imveliso. isandi sokunwebeka.I-Tin-zinc bronze: ubuninzi be-zinc buchithwa kwi-alloy ye-copper-tin, kwaye ngoko ke ukongezwa kwe-zinc kwi-bronze ye-tin ekhubazekile ngokuqhelekileyo ingaphantsi kwe-4%.I-Zinc inokuphucula i-fluidity ye-alloy, icuthe i-crystallization yeqondo lokushisa, kunye nokunciphisa ulwahlulo oluguqukayo.
