Isakhiwo sokumboza somugqa wensimbi we-galvalume yi-Zn-Al alloy, futhi ukwakheka kokumboza kungu-55% Al, 43.3% Zn, no-1.6% Si.Ngenxa yokumelana nokugqwala okuhle kakhulu, lolu hlobo lwensimbi lusetshenziswa kabanzi emhlabeni wonke.
Ukuthuthukiswa kwensimbi ye-azizinc.Mayelana nokuhlinzekwa kanye nesidingo, ngemva kweminyaka yokulungiswa nokuncintisana kwemakethe, imboni yaseChina yamakhoyili ensimbi ye-galvalume isizinzile kancane kancane.Ubudlelwano bokuhlinzekwa kwemakethe kanye nesidingo buyalingana.Izinga lokukhiqiza nokuthengisa lingaphezu kwama-90% njalo ngonyaka, futhi inani elikhulu lemikhiqizo lithunyelwa kwamanye amazwe minyaka yonke.
