Anthu akagula maloko, amakhala ndi nkhawa kuti loko sikolimba kapena pasanapite nthawi yaitali kuti pamwamba pakhale dzimbiri kapena oxidation.Vutoli limakhudzana ndi zinthu zomwe zimagwiritsidwa ntchito komanso chithandizo chapamwamba.
Kuchokera kumalo okhazikika, zinthu zabwino kwambiri ziyenera kukhala zitsulo zosapanga dzimbiri, makamaka ngati pamwamba, zomwe zimagwiritsidwa ntchito kwambiri zimakhala zowala kwambiri.Mphamvu zake, kukana kwa dzimbiri, mtundu wosasinthika.Koma palinso zosiyanasiyana zitsulo zosapanga dzimbiri, makamaka akhoza kugawidwa mu ferrite ndi austenitic.Ferritic zitsulo zosapanga dzimbiri zimakhala ndi maginito, zomwe zimadziwika kuti chitsulo chosapanga dzimbiri, nthawi yayitali, chilengedwe sichikhala chabwino, chitsulo chosapanga dzimbiri chokha cha austenitic sichichita dzimbiri, chizindikiritso cha njira ndi chophweka, ndi maginito amatha kudziwika.
Mkuwa ndi mmodzi wa anthu ambiri ntchito loko zipangizo, ndi katundu wabwino makina, kukana zabwino dzimbiri ndi processing katundu, ndi mtundu wowala, makamaka chogwirira ndi zina loko kukongoletsa mbali mkuwa forging, yosalala pamwamba, kachulukidwe wabwino, palibe pores, sandholes.Zomwe zili kale ndi dzimbiri zolimba, zimatha kugwiritsa ntchito golide wa 24K kapena mitundu yonse yopangira zinthu monga golide wa placer, kuwoneka wokongola, wapamwamba komanso wosavuta, nyumba yomwe imapatsa anthu mitundu yambiri.
Zinc alloy zakuthupi, mphamvu zake ndi kukana dzimbiri ndizoipa kwambiri, koma ubwino wake ndi wosavuta kupanga mapangidwe ovuta a zigawo, makamaka kuponyera.Chotsekera chomwe mawonekedwe ovuta kwambiri omwe msika amawona ndizotheka kukhala aloyi ya zinki amachitidwa mochuluka, ogula amafuna kusiyanitsa mosamala.
Chitsulo ndi zitsulo, mphamvu zabwino, otsika mtengo, koma zosavuta dzimbiri, ambiri ntchito ngati loko mkati mwazomangamanga zipangizo, osati kunja kukongoletsa mbali.
Aluminiyamu kapena zitsulo zotayidwa, zotayira wamba (kupatula zakuthambo) ndizofewa komanso zopepuka, zokhala ndi mphamvu zochepa koma zosavuta kupanga.
