Ingxubevange yobheduyingxubevange eyenziwe ngobhedu olusulungekileyo njengematrix kunye nenye okanye izinto ezininzi ezongeziweyo.Ngokwendlela yokwenza izinto, inokwahlulwa ibe yi-alloy yobhedu ephothiweyo kunye ne-alloy yobhedu ekhubazekileyo.
Uninzi lweealloyi zobhedu ezityhidiweyo azinakusetyenziswa, ezifana ne-beryllium yobhedu kunye ne-tin bronze, ezi ngxubevange zineplastiki embi kakhulu kwaye ayikwazi ukusetyenzwa.Ubhedu olusulungekileyo ngokuqhelekileyo lubizwa ngokuba lubhedu olubomvu.I-conductivity yayo yombane, i-thermal conductivity, i-corrosion resistance and plasticity igqwesile, kodwa amandla ayo kunye nokuqina kwayo kuphantsi, kwaye kuyabiza.Ngoko ke, ayifane isetyenziswe ukwenza iinxalenye.Iialloyi zobhedu zisetyenziswa kakhulu koomatshini.I-Brass yi-alloy yobhedu ene-zinc njengeyona nto iphambili.
Ngokunyuka komxholo we-zinc, amandla kunye neplastiki ye-alloy yanda kakhulu, kodwa iimpawu zayo zomatshini ziya kuncipha kakhulu xa zidlula 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.Iimpawu zomatshini wobhedu otyhidiweyo ziphezulu kunezobhedu, kodwa ixabiso lingaphantsi kunelobhedu.I-Cast brass isoloko isetyenziselwa iinjongo ezithwele i-bushings, i-bushings, iigiya kunye nezinye iindawo zokunxiba kunye neevalvu kunye nezinye iindawo ezinganyangekiyo.
Ingxubevange eyenziwe ngezinto ezingaphandle kobhedu kunye ne-zinc zibizwa ngokudibeneyo njengobhedu.Phakathi kwazo, i-alloy yobhedu kunye ne-tin yeyona nto ixhaphakileyo yobhedu, ebizwa ngokuba yi-tin bronze.I-tin bronze ine-low linear shrinkage kwaye akulula ukuvelisa i-shrinkage cavities, kodwa kulula ukuvelisa i-shrinkage microscopic.Ukongezwa kwe-zinc, i-lead kunye nezinye izinto kwi-bronze ye-tin kunokuphucula ukuxinana kunye nokunxiba ukuxhathisa ukuphosa, gcina inani le-tin, kwaye ungeze i-phosphorus ye-deoxidation.Nangona kunjalo, kulula ukuvelisa i-micro-shrinkage, ngoko ifanelekile kwiindawo zokunxiba kunye ne-corrosion-resistant-resistant ezingadingi ukuqina okuphezulu.
Ukongeza kubhedu lwe-tin, ubhedu lwe-aluminiyam luneempawu ezibalaseleyo zoomatshini kunye nokumelana nokunxiba kunye nokumelana nokugqwala, kodwa ukuphosa kwayo kubi, ngoko ke isetyenziselwa kuphela ukunxiba okubalulekileyo kunye neenxalenye zokumelana nokubola.Iialloys ezininzi zobhedu zingasetyenziselwa zombini ukuphosa kunye nokukhubazeka.Ngokuqhelekileyo i-alloys yobhedu esetyenzisiweyo ingasetyenziselwa ukuphosa, ngelixa ezininzi ii-alloys zobhedu azikwazi ukukhubazeka ezifana ne-forging, extrusion, umzobo onzulu kunye nokuzoba.
