Ipleyiti yobhedu yenkcenkceukubunjwa yintsimbi yobhedu ukuvelisa iicastings.Ukufakwa kweBronze kusetyenziswa kakhulu kwimveliso yoomatshini, iinqanawa, iimoto, ulwakhiwo kunye namanye amacandelo oshishino, ukwenza uthotho lobhedu oluphonsiweyo kwizinto ezinzima zetsimbi ezingenayo i-ferrous.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 we-solubility ye-phosphorus kwi-Hebei tin bronze yi-0.15%, ukuba ubuninzi obugqithisileyo, iyakwenza i-α+δ+Cu3P ternary eutectic, indawo yokukhenkceza yi-628℃, kulula ukubonelela ngokukrakra okushushu ngexesha lokuqengqeleka okushushu, ngoko ke kungasebenza 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.Iimathiriyeli 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, iplastikhi, umda weelastiki kunye nemodyuli yokwaleka kwentengiso, kunye nokwandisa 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 uluhlu lwe-crystallization yeqondo lokushisa, kunye nokunciphisa ulwahlulo oluguqukayo.
