Ukukhishwa kwe-Brass kusetshenziswa kabanzi ku-valve nenkundla yepompo ngenxa yokusebenza okuhle kakhulu kwezinto zethusi. Kwa-RMC Foundry, sikhiqiza ikakhulukazi iama-castings ethusingokujikijelwa kwesihlabathi esiluhlaza, ukujikijelwa kwesihlabathi nge-resin,ukutshala imalifuthi ekubunjweni okukhulu kwethusi, siphinde sithathe inqubo yokuphonsa igwebu elahlekile kanye ne-vacuum casting. Ngokuvamile, ukulingwa kwethusi okukhiqizwa ngokusakazwa kwesihlabathi kuyisigaba esiyinhloko endaweni yethu.
I-alloy yethusi ene-zinc njengengxenye eyinhloko ye-alloying ngokuvamile ibizwa ngokuthi ithusi. I-alloy kanambambili ye-Copper-zinc ibizwa ngokuthi ithusi elijwayelekile, kanti i-ternary, i-quaternary noma i-multi-element yethusi eyakhiwe ngokungeza inani elincane lezinye izakhi ngesisekelo se-alloy yethusi-zinc ibizwa ngokuthi ithusi elikhethekile. I-Cast brass isetshenziselwa ukukhiqiza ithusi lokulingisa. I-Brass castings isetshenziswa kabanzi ekukhiqizeni imishini, i-valve namaphampu, imikhumbi, izindiza, izimoto, ukwakhiwa kanye neminye imikhakha yezimboni, ethatha isisindo esithile ezintweni zensimbi ezisindayo ezingezona ayoni, zakha uchungechunge lwethusi.
Uma kuqhathaniswa nethusi nethusi, ukuncibilika okuqinile kwe-zinc ethusi kukhulu kakhulu. Ngaphansi kokulingana okujwayelekile kwezinga lokushisa, cishe amaphesenti angama-37 e-zinc angancibilika ethusi, futhi cishe u-30% we-zinc angancibilika esimweni sokuphonswa, kuyilapho ithusi eliwuthayela Esimeni sokuphonswa, ingxenye enkulu yokuncibilika okuqinile kwethini. ethusi ku-5% kuya ku-6% kuphela. Ingxenye enkulu ye-solubility eqinile ye-aluminium yethusi i-7% kuya ku-8% kuphela. Ngakho-ke, i-zinc inomphumela omuhle wokuqinisa isisombululo ethusi. Ngesikhathi esifanayo, izakhi eziningi ze-alloying zingaphinde zihlakazwe ngethusi kuya ngamazinga ahlukahlukene , Ngokuqhubekayo uthuthukise izakhiwo zayo zemishini, ukuze ithusi, ikakhulukazi ithusi elikhethekile libe nezici zamandla aphezulu. Intengo ye-zinc iphansi kune-aluminium, ithusi, ne-tin, futhi inothile ngezinsiza. Inani le-zinc elengezwe ethusi likhulu kakhulu, ngakho-ke izindleko zethusi ziphansi kunethusi le-tin ne-aluminium bronze. I-Brass inebanga lokushisa elincane lokuqina, uketshezi oluhle, kanye nokuncibilika okulula.
Ngenxa yokuthi ithusi linezici ezibalulwe ngenhla zamandla aphezulu, intengo ephansi nokusebenza okuhle kokulingisa, ithusi linezinhlobo eziningi, okukhiphayo okukhulu kanye nokusetshenziswa okubanzi kunethusi lethini nethusi le-aluminium kuma-alloys ethusi. Kodwa-ke, ukumelana nokugqwala nokumelana nokugqwala kwethusi akukuhle njengethusi, ikakhulukazi ukumelana nokugqwala nokumelana nokugqoka kwethusi elijwayelekile kuphansi kakhulu. Kuphela lapho ezinye izakhi ze-alloy zengezwa ukuze zenze ithusi elikhethekile elihlukahlukene, ukumelana kwayo nokugqoka nokusebenza kokugqwala kokumelana kuye kwathuthukiswa futhi kwathuthukiswa.
Ukulingisa ngethusi nokulingisa kwethusi kokubili kuyingxubevange yengxubevange yethusi engasakazwa ngokusakazwa kwesihlabathi kanye nezinqubo zokutshala imali. I-Brass iyingxube ye-alloy eyakhiwe ngethusi ne-zinc. I-Brass eyakhiwe ngethusi ne-zinc ibizwa ngokuthi ithusi elijwayelekile. Uma kuyizinhlobonhlobo zama-alloys ezakhiwe izakhi ezingaphezu kwezimbili, kubizwa ngokuthi ithusi elikhethekile. I-Brass iyingxube yethusi ene-zinc njengento eyinhloko. Njengoba okuqukethwe kwe-zinc kwanda, amandla kanye ne-plasticity ye-alloy yanda kakhulu, kodwa izakhiwo zemishini zizokwehla kakhulu ngemva kokudlula i-47%, ngakho-ke okuqukethwe kwe-zinc yethusi kungaphansi kuka-47%. Ngaphezu kwe-zinc, ithusi elikhonjiwe livame ukuqukatha izakhi ze-alloying ezifana ne-silicon, i-manganese, i-aluminium, nomthofu.
