Ingxube yethusiiyingxubevange eyakhiwe ngethusi elimsulwa njenge-matrix kanye nesici esisodwa noma ezimbalwa zengezwe.Ngokusho kwendlela yokwakheka kwezinto, ingahlukaniswa ibe yi-alloy yethusi ekhonjiwe kanye ne-alloy yethusi ekhubazekile.
Ama-alloys amaningi e-copper cast awakwazi ukucindezelwa, njenge-cast beryllium bronze kanye ne-cast tin bronze, lawa ma-alloys ane-plasticity embi kakhulu futhi awakwazi ukusebenza ngokucindezela.Ithusi elihlanzekile ngokuvamile liyaziwa ngokuthi ithusi elibomvu.I-conductivity yayo kagesi, i-thermal conductivity, ukumelana nokugqwala kanye ne-plasticity kuhle kakhulu, kodwa amandla ayo nokuqina kwayo kuphansi, futhi kuyabiza.Ngakho-ke, akuvamile ukusetshenziselwa ukwenza izingxenye.Ama-alloys ethusi asetshenziswa kakhulu emishinini.I-Brass iyingxube yethusi ene-zinc njengento eyinhloko.
Ngokukhula kokuqukethwe kwe-zinc, amandla kanye ne-plasticity ye-alloy yanda kakhulu, kodwa izakhiwo zayo zemishini zizokwehla kakhulu uma zidlula i-47%, ngakho-ke okuqukethwe kwe-zinc yethusi kungaphansi kwama-47%.Ngaphezu kwe-zinc, ithusi elikhonjiwe livame ukuqukatha izakhi ze-alloying ezifana ne-silicon, i-manganese, i-aluminium, nomthofu.Izakhiwo zemishini yethusi elikhonjiwe ziphakeme kunezethusi, kodwa intengo iphansi kunaleyo yethusi.I-Cast brass ivamise ukusetshenziswa ezihlahleni ezithwala inhloso ejwayelekile, izihlahla, amagiya nezinye izingxenye zokugqokwa namavalvu nezinye izingxenye ezimelana nokugqwala.
Ama-alloys akhiwe ngezinto ngaphandle kwethusi ne-zinc abizwa ngokuhlanganyela njengethusi.Phakathi kwazo, i-alloy yethusi ne-tin iyithusi elivame kakhulu, elibizwa nge-tin bronze.Ithusi eliwuthayela linokuncipha komugqa okuphansi futhi akulula ukukhiqiza izimbotshana ezinciphayo, kodwa kulula ukukhiqiza ukushwabana okuncane kakhulu.Ukwengezwa kwe-zinc, i-lead nezinye izakhi ku-tinthusi kungathuthukisa ukubumbana nokugqoka ukumelana nokusakazwa, konga inani le-tin, futhi kwengeze i-phosphorus ye-deoxidation.Kodwa-ke, kulula ukukhiqiza i-micro-shrinkage, ngakho-ke ifaneleka ezingxenyeni ezingagugi futhi ezivimbela ukugqwala ezingadingi ukuhlangana okuphezulu.
Ngaphezu kwethusi le-tin, ithusi le-aluminium linezakhiwo ezinhle kakhulu zemishini kanye nokumelana nokugqoka kanye nokumelana nokugqwala, kodwa ukuqina kwayo kubi, ngakho-ke isetshenziselwa kuphela ukugqoka okubalulekile kanye nezingxenye zokumelana nokugqwala.Ama-alloys amaningi e-copper angasetshenziselwa kokubili ukuphonsa nokulimaza.Ngokuvamile ama-alloys ethusi enziwe angasetshenziselwa ukusakaza, kuyilapho ama-alloys ethusi amaningi e-cast angeke akhubazeke njengokubumba, ukukhipha, ukudweba okujulile nokudweba.
