Ipuleti lethusi likathayelaukubunjwa kuyinto yethusi wont ukukhiqiza castings.Ama-Bronze castings asetshenziswa kabanzi ekwenziweni kwemishini, imikhumbi, izimoto, ezokwakha kanye neminye imikhakha yezimboni, kwakha uchungechunge lwethusi olusansimbi ezintweni zensimbi ezisindayo ezingezona ayoni.Ama-bronze ajwayelekile asetshenziswa yi-tin bronze plate, i-lead bronze, i-Muntz metal ne-aluminium bronze.ukuncipha kwenani lengxubevange ye-Cu-Sn kuncane kakhulu (izinga lokushwabana komugqa ngu-1.45% kuya ku-1.5%), futhi kulula ukunikeza ukulingisa okuyinkimbinkimbi nemisebenzi yezandla ngamaphethini acacile adinga ubukhulu obunembile.Ethusi lethini elingagugi, okuqukethwe kwe-phosphorus kuvame ukuba phezulu njengo-1.2%.I-Zinc ingathuthukisa i-fluidity ye-alloy futhi inciphise ukuthambekela kokuhlehla kokuhlukaniswa kwethusi le-tin.Umthofu uthuthukisa kakhulu ukumelana nokuguga kanye nokuguquguquka kwe-alloy.I-Cast tin bronze isetshenziswa njengezingxenye ezimelana nokuguga nokubola.I-Tin Phosphor Bronze: I-Phosphorus ingaba i-deoxidizer enhle yama-alloys ethusi, engase ikhulise uketshezi lwengxubevange, ithuthukise izici zobuchwepheshe nezomshini zethusi lethini, kodwa ikhulise izinga lokuhlukaniswa okuhlanekezelwe.Umkhawulo wokunyibilika kwe-phosphorus ku-Hebei tin bronze ngu-0.15%, uma inani elidlulele, izokwakha u-α+δ+Cu3P ternary eutectic, indawo yokuqandisa ngu-628℃, kulula ukunikeza i-hot brittleness ngesikhathi sokuginqika okushisayo, ngakho-ke kungasebenza kuphela ukubanda.Ngakho-ke, okuqukethwe kwe-phosphorus ku-tin bronze ekhubazekile akufanele kube ngaphezu kuka-0.5%, ngakho-ke i-phosphorus kufanele ibe ngu-0.25% ngesikhathi sokusebenza okushisayo.Ithusi eliqukethe i-phosphorus lingaba into eyaziwayo enwebekayo.Ngesikhathi sokucutshungulwa, kuyadingeka ukuphatha usayizi wokusanhlamvu ngaphambi kokusebenza okubandayo kanye nokushunqiswa okubandayo ngemva kokucubungula.Amandla, i-modulus ye-elasticity kanye namandla okukhathala kwezinto ezihlanjululwe kahle zingaphezu kwalezo ze-coarse-grained material, kodwa ipulasitiki iphansi.Izinto ezisetshenzwe ngokubanda zifakwa ezingeni lokushisa lekhofi elingu-200-260 ℃ amahora angu-1-2, okuholela ekubambeni nasekuqineni, okungase kuthuthukise amandla, ukuqina kwepulasitiki, umkhawulo wokunwebeka kanye ne-modulus yokunwebeka kokuthengiswayo, futhi kwandise ukuzwakala kokunwebeka.Ithusi le-tin-zinc: inani elikhulu kakhulu le-zinc lincibilika ku-alloy ye-copper-tin, ngakho-ke ukufakwa kwe-zinc kuthusi elikhubazekile le-tin ngokuvamile lingaphansi kuka-4%.I-Zinc ingathuthukisa i-fluidity ye-alloy, inciphise izinga lokushisa le-crystallization, futhi yehlise ukuhlukaniswa okuhlanekezelwe.
