Iintsimbi zobhedu zisetyenziswa ngokubanzi kwi-valve kunye nentsimi yepompo ngenxa yokusebenza kakuhle kwezinto zobhedu. Kwi-RMC Foundry, sivelisa ubukhulu becalaiicastings zobhedungokugalela isanti eluhlaza, ukugalelwa kwentlabathi egqunywe intlaka,utyalo malikunye nokuphosa okukhulu kobhedu, sikwathatha inkqubo yokuphosa ugwebu elahlekileyo kunye nenkqubo yokuphosa ivacuum. Ngokuqhelekileyo, ubhedu oluveliswa ngokusantiweyo luluhlu oluphambili kwisiseko sethu.
I-alloy yobhedu enezinki njengeyona nto iphambili yokudibanisa idla ngokubizwa ngokuba lubhedu. I-Copper-zinc i-alloy ye-binary ebizwa ngokuba yi-brass eqhelekileyo, kunye ne-ternary, i-quaternary okanye i-multi-element yobhedu eyenziwe ngokudibanisa inani elincinci lezinye izinto ngesiseko se-copper-zinc alloy ibizwa ngokuba lubhedu olukhethekileyo. I-Cast brass isetyenziselwa ukuvelisa ubhedu bokubunjwa. Ukuphoswa kobhedu kusetyenziswa kakhulu kwimveliso yoomatshini, ivalve kunye neempompo, iinqanawa, inqwelomoya, iimoto, ulwakhiwo kunye namanye amacandelo oshishino, ezithatha ubunzima obuthile kwizinto ezinzima zentsimbi ezingenayo intsimbi, zenza uthotho lobhedu oluphothiweyo.
Xa kuthelekiswa nobhedu kunye nobhedu, ukunyibilika okuqinileyo kwe-zinc kubhedu kukhulu kakhulu. Ngaphantsi kokulinganisa okuqhelekileyo kweqondo lokushisa, malunga ne-37% ye-zinc inokuchithwa kwi-copper, kwaye malunga ne-30% ye-zinc inokuchithwa kwimeko ye-as-cast, ngelixa i-tin bronze Kwimeko ye-as-cast, iqhekeza elikhulu le-solubility eqinile ye-tin. kubhedu yi-5% ukuya kwi-6% kuphela. Ubuninzi beqhezu lokunyibilika okuqinileyo kwe-aluminium yobhedu kubhedu kuphela yi-7% ukuya kwi-8%. Ngoko ke, i-zinc inesisombululo esihle esiqinileyo sokuqinisa ubhedu. Ngelo xesha, izinto ezininzi ezixutywayo nazo zinokuchithwa ngobhedu ukuya kwii-degrees ezahlukeneyo , Ukuqhubela phambili ukuphucula iimpawu zayo zemishini, ukwenzela ukuba ubhedu, ngokukodwa ubhedu obukhethekileyo buneempawu zamandla aphezulu. Ixabiso le-zinc lisezantsi kune-aluminiyam, ubhedu, kunye ne-tin, kwaye ityebile kwimithombo. Isixa se-zinc esongeziweyo kubhedu sikhulu, ngoko ke ixabiso lobhedu liphantsi kune-tin bronze kunye ne-aluminium bronze. I-Brass inoluhlu oluncinci lobushushu bokuqina, ulwelo olulungileyo, kunye nokunyibilikiswa okufanelekileyo.
Ngenxa yokuba ubhedu luneempawu ezikhankanywe ngasentla zamandla aphezulu, ixabiso eliphantsi kunye nokusebenza kakuhle kokuphosa, ubhedu luneentlobo ezininzi, imveliso enkulu kunye nesicelo esibanzi kunobhedu lwe-tin kunye ne-aluminium yobhedu kwii-alloys zobhedu. Nangona kunjalo, ukuxhathisa ukunxiba kunye nokumelana nokubola kobhedu akulunganga njengobhedu, ngakumbi ukuxhathisa ukubola kunye nokumelana nokunxiba kobhedu oluqhelekileyo kuphantsi. Kuphela xa ezinye izinto ze-alloy zongezwa ukwenza iintlobo ezahlukeneyo zobhedu olukhethekileyo, ukuxhathisa kwayo kunye nokuchasana nokusebenza kwe-corrosion kuye kwaphuculwa kwaye kwaphuculwa.
Ukwenziwa kobhedu kunye nobhedu olutyhidiweyo zombini lubhedu olusekwe kwingxubevange yealloyi enokuphoswa ngokugalelwa kwesanti kunye neenkqubo zotyalo-mali. Ubhedu yi-alloy eyenziwe ngobhedu kunye ne-zinc. Ubhedu olwakhiwe ngobhedu kunye ne-zinc lubizwa ngokuba lubhedu oluqhelekileyo. Ukuba luhlobo lwe-alloys oluqulunqwe ngaphezu kwezinto ezimbini, kuthiwa lubhedu olukhethekileyo. I-Brass yi-alloy yobhedu ene-zinc njengeyona nto iphambili. Njengoko umxholo we-zinc ukhula, amandla kunye neplastiki ye-alloy yanda kakhulu, kodwa iimpawu zomatshini ziya kuncipha kakhulu emva kokudlula i-47%, ngoko umxholo we-zinc wobhedu ungaphantsi kwama-47%. Ukongeza kwi-zinc, ubhedu oluphosiweyo luhlala luqulethe izinto ezixubileyo ezifana ne-silicon, i-manganese, i-aluminium kunye nelothe.
