Isinyithi esasisetyenziselwa ukuphosa ukufa ikakhulu ziquka i-zinc, ubhedu, i-aluminiyam, i-magnesium, ilothe, i-tin, kunye ne-alloys ye-lothe-tin njl. Iimpawu zetsimbi ezahlukeneyo ngexesha lokufa zimi ngolu hlobo lulandelayo:
•Zinc: Esona sinyithi sokufa ngokulula, sinoqoqosho xa sisenza iindawo ezincinci, kulula ukunxiba, amandla acinezelayo aphezulu, iplastiki ephezulu, kunye nobomi obude bokuphosa.
•Aluminiyam: Umgangatho ophezulu, ukuveliswa okunzima kunye nokuxhonywa kweendonga ezinqabileyo ezinozinzo oluphezulu, ukuxhathisa okuphezulu kwe-corrosion, iipropathi ezilungileyo ze-mechanical, conductivity ephezulu ye-thermal kunye ne-conductivity yombane, kunye namandla aphezulu kumaqondo okushisa aphezulu.
•Magnesium: Kulula ukwenza umatshini, amandla aphezulu kumlinganiselo wobunzima, eyona ilula kwiintsimbi ezisetyenziswa ngokuqhelekileyo.
•Ubhedu: Ubulukhuni obuphezulu kunye nokumelana nokugqwala okuqinileyo. Eyona isetyenziswa ngokuqhelekileyo i-die-cast metal ineempawu ezingcono kakhulu zemishini, i-anti-wear kunye namandla asondele kwintsimbi.
•Ilothe kunye netoti: Uxinaniso oluphezulu kunye nokuchaneka okuphezulu kwe-dimensional yeendawo ezikhethekileyo zokukhusela i-corrosion. Ngenxa yezizathu zempilo yoluntu, le ngxubevange ayinakusetyenziswa njengendawo yokulungisa nokutya. Ingxubevange ye-lead-tin-bismuth (ngamanye amaxesha ikwaqulathe ubhedu oluncinci) ingasetyenziselwa ukwenza amagama agqitywe ngesandla kunye nesitampu esishushu kushicilelo lweletterpress.
