Li-castings tsa koporo li sebelisoa haholo sebakeng sa valve le pompo ka lebaka la ts'ebetso e ntle ea lisebelisoa tsa koporo. Ho RMC Foundry, re hlahisa lihlahisoa tsali-castings tsa koporoka ho lahla lehlabathe le letala, lehlabathe le koahetsoeng ka resin;ho kenya cheletele bakeng sa lisebelisoa tse kholo tsa koporo, re boetse re amohela mokhoa o lahlehileng oa ho lahlela foam le vacuum casting. Ka kakaretso, li-castings tsa koporo tse hlahisoang ke ho lahla lehlabathe ke tsona tse ka sehloohong setsing sa rona.
Alloy ea koporo e nang le zinki joalo ka karolo ea mantlha ea alloying hangata e bitsoa koporo. Copper-zinc binary alloy e bitsoa koporo e tloaelehileng, 'me koporo ea ternary, quaternary kapa multi-element e thehoa ka ho eketsa karolo e nyenyane ea lintho tse ling motheong oa koporo-zinki alloy e bitsoa koporo e khethehileng. Cast brass e sebelisoa ho hlahisa koporo bakeng sa li-castings. Li-castings tsa Brass li sebelisoa haholo indastering ea ho etsa mechine, li-valve le lipompo, likepe, lifofane, likoloi, kaho le likarolo tse ling tsa indasteri, tse nang le boima bo itseng ka thepa e boima ea tšepe e se nang ferrous, ho etsa letoto la koporo.
Ha ho bapisoa le koporo le boronse, ho qhibiliha ho tiileng ha zinki ka koporo ho hoholo haholo. Tlas'a tekano e tloaelehileng ea mocheso, hoo e ka bang 37% ea zinki e ka qhibiliha ka koporo, 'me hoo e ka bang 30% ea zinki e ka qhibiliha sebakeng sa as-cast, ha tin bronze. ka koporo ke feela 5% ho 6%. Karolo e kholo ea solubility e tiileng ea boronse ea aluminium ka koporo ke 7% ho isa ho 8%. Ka hona, zinki e na le phello e ntle e tiileng ea ho matlafatsa koporo. Ka nako e ts'oanang, likarolo tse ngata tsa alloying li ka boela tsa qhibiliha ka koporo ho likhato tse sa tšoaneng , Ho feta moo ho ntlafatsa thepa ea eona ea mechine, e le hore koporo, haholo-holo koporo e khethehileng e na le litšobotsi tsa matla a phahameng. Theko ea zinki e tlase ho feta ea aluminium, koporo le thini, 'me e na le lisebelisoa tse ngata. Palo ea zinki e kenyelletsoeng ka koporo e batla e le khōlō, kahoo theko ea koporo e tlaase ho feta tin bronze le aluminium bronze. Brass e na le mocheso o fokolang oa ho tiisa, metsi a matle, le ho qhibiliha ha bonolo.
Hobane koporo e na le litšobotsi tse boletsoeng ka holimo tsa matla a phahameng, theko e tlaase le ts'ebetso e ntle ea ho lahla, koporo e na le mefuta e mengata, tlhahiso e kholoanyane le ts'ebeliso e pharaletseng ho feta boronse ba tin le boronse ba aluminium ka li-alloys tsa koporo. Leha ho le joalo, khanyetso ea ho roala le ho hanyetsa ha kutu ea koporo ha e ntle joaloka boronse, haholo-holo ho hanyetsa kutu le ho roala ha koporo e tloaelehileng e batla e le tlaase. Ke feela ha likarolo tse ling tsa alloy li eketsoa ho theha koporo e khethehileng e fapaneng, ts'ebetso ea eona ea ho hanyetsa le ho hanyetsa ts'ebetso e ntlafalitsoe le ho ntlafatsoa.
Li-castings tsa koporo le li-bronze ka bobeli ke li-alloy castings tse entsoeng ka koporo tse ka hlahisoang ke ho lahla lehlabathe le mekhoa ea ho etsa matsete. Brass ke motsoako o entsoeng ka koporo le zinki. Brass e entsoeng ka koporo le zinki e bitsoa koporo e tloaelehileng. Haeba e le mefuta e fapaneng ea li-alloys e entsoeng ka likarolo tse fetang tse peli, e bitsoa koporo e khethehileng. Brass ke motsoako oa koporo o nang le zinki e le ntho e ka sehloohong. Ha lihlahisoa tsa zinki li ntse li eketseha, matla le polasetiki ea alloy li eketseha haholo, empa thepa ea mochine e tla fokotseha haholo ka mor'a ho feta 47%, kahoo zinki tsa koporo li ka tlaase ho 47%. Ho phaella ho zinki, koporo e entsoeng hangata e na le lisebelisoa tsa alloying tse kang silicon, manganese, aluminium le lead.
