Lapho abantu bethenga izingidi, ngokuvamile bakhathazeka ngokuthi ukukhiya akuhlali isikhathi eside noma kungakabiphi ngemuva kokuthi indawo izogqwala noma i-oxidation.Le nkinga ihlobene nezinto ezisetshenziswayo kanye nokwelashwa okungaphezulu.
Ngokombono oqinile, impahla engcono kakhulu kufanele kube insimbi engagqwali, ikakhulukazi njengempahla engaphezulu, lapho isetshenziswa kakhulu yilapho ikhanya kakhulu.Amandla ayo, ukumelana nokugqwala, umbala awushintshile.Kodwa kukhona futhi izinhlobonhlobo zensimbi engagqwali, ikakhulukazi zingahlukaniswa zibe ferrite futhi austenitic.Insimbi engagqwali Ferritic has kazibuthe, ngokuvamile eyaziwa ngokuthi insimbi engagqwali, isikhathi eside, imvelo akukuhle ngeke ukugqwala, kuphela insimbi engagqwali austenitic ngeke ukugqwala, ukuhlonza indlela ilula kakhulu, nge uzibuthe kuyabonakala.
I-Copper ingenye yezinto ezisetshenziswa kakhulu zokukhiya, enezici ezinhle zemishini, ukumelana nokugqwala okuhle nokucubungula izakhiwo, nombala ogqamile, ikakhulukazi isibambo kanye nezinye izingxenye zokuhlobisa zokukhiya zethusi, ubuso obushelelezi, ukuminyana okuhle, azikho izimbotshana, ama-sandholes.Kakade iqinile, ingakwazi ukusebenzisa igolide elingu-24K noma zonke izinhlobo zokucutshungulwa kwendawo efana negolide le-placer, ibonakale iyinhle, iphakeme futhi ilula, indlu enikeza abantu imibala eminingi.
I-Zinc alloy material, amandla ayo kanye nokumelana nokugqwala kubi kakhulu, kodwa inzuzo yayo kulula ukwenza amaphethini ayinkimbinkimbi wezingxenye, ikakhulukazi ukucindezela ukucindezela.Ilokhi idizayini eyinkimbinkimbi kakhulu ebonwa indawo yemakethe kungenzeka ibe yingxubevange ye-zinc yenziwa kakhulu, umthengi ufuna ukuhlukanisa ngokucophelela.
Insimbi nensimbi, amandla amahle, izindleko eziphansi, kodwa kulula ukugqwala, ngokuvamile isetshenziswa njengendlela yokukhiya izinto zokwakha zangaphakathi, hhayi njengezingxenye zokuhlobisa zangaphandle.
I-aluminium noma i-aluminium alloys, ama-alloys ajwayelekile e-aluminium (ngaphandle kwe-aerospace) athambile futhi alula, anamandla aphansi kodwa kulula ukuwenza.
