Ithusi likathayelaamandla adonsela phansi aqondile ρ (8.82).Ithusi lingahlukaniswa izigaba ezimbili: ithusi lethayela kanye nethusi elikhethekile (okungukuthi i-Wuxi bronze).Ngemikhiqizo yokusakaza, engeza igama elithi “Z” ngaphambi kwekhodi, njengokuthi: I-Qal7 isho ukuthi okuqukethwe kwe-aluminium kungu-5%, okunye kuyithusi.I-Copper casting tin bronze Ithusi lensimbi iyingxubevange ye-copper-tin enethini njengento eyinhloko, eyaziwa nangokuthi i-tin bronze.Lapho okuqukethwe kwe-tin kungaphansi kuka-5 ~ 6%, ithini lincibilika ngethusi ukuze lenze isisombululo esiqinile, futhi ipulasitiki iyanda.Uma inani likhulu kuno-5 ~ 6%, amandla okuqina ayehla ngenxa yokubukeka kwesisombululo esiqinile esisekelwe ku-Cu31sb8, ngakho-ke okuqukethwe kwe-tin esikalini sethusi kuphakathi kuka-3 ~ 14%.Uma okuqukethwe kwethini kungaphansi kuka-5%, ifanele ukupholiswa.Ukucutshungulwa kwe-Deformation, lapho okuqukethwe kwe-tin kungu-5-7%, kufanelekile ukucubungula ukushisa okushisayo.Uma okuqukethwe kwethini kungaphezu kuka-10%, ifaneleka ukusakaza.Njengoba amandla e-a kanye & & efanayo, futhi ithini ekubunjweni kwayo i-nitrided ukuze yakhe ifilimu ye-tin dioxide eminyene, ukumelana nokugqwala komkhathi namanzi olwandle kuyathuthukiswa, kodwa ukumelana ne-asidi kubi.Ngenxa yokuthi ithusi eliwuthayela linobubanzi obubanzi bezinga lokushisa elicwebezelayo kanye nokungamanzi kahle, akulula ukwenza izimbobo zokushwabana ezigxilile, kodwa kulula ukwenza ukuhlukaniswa kwe-dendrite nezimbobo zokushwabana ezihlakazekile.Umumo oyinkimbinkimbi.Izimo zokushuba kodonga olukhulu azifaneleki ukulingisa okudinga ukuminyana okuphezulu nokubekwa uphawu okuhle.I-tin bronze ine-anti-friction enhle, i-anti-magnetic kanye nokuqina kwezinga lokushisa eliphansi.
