Nickel na tushen gami waldi waya yana da kyau yi na juriya ga aiki gas, caustic matsakaici, lalata juriya don rage acid matsakaici, kuma yana da babban ƙarfi, mai kyau plasticity, sanyi da zafi nakasawa da aiki da walda halaye, sabili da haka, yadu amfani da petrochemical. karafa, atomic makamashi, marine ci gaban, jirgin sama, aerospace da sauran masana'antu, don warware janar bakin karfe da sauran karafa, wadanda ba karfe kayan ba zai iya magance matsalar lalata injiniya, yana da matukar muhimmanci lalata-resistant karfe abu. Abubuwan da ake amfani da su na nickel suna magana ne akan abubuwan da ke tushen nickel kuma suna ƙunshe da abubuwan haɗin gwiwa kuma suna iya tsayayya da lalata a wasu kafofin watsa labarai. Lokacin da aka rarraba ta hanyar abubuwan da ke tattare da sinadarai, akwai musamman nickel, nickel-copper alloys, nickel-molybdenum (nickel-molybdenum ferrolybdenum) gami da nickel-chromium (nickel-chromium-iron) gami, nickel-chromium-molybdenum (ciki har da nickel-chromium). -molybdenum gami da nickel-chromium-molybdenum jan karfe gami da nickel-iron chromium (duka baƙin ƙarfe-tushen gami) da sauran nau'ikan. Ana amfani da waya mai walƙiya mai tsaftar nickel ERNi-1 don walda 200, 201 nickel gami da farantin karfe na nickel-plated; walda na karfe da nickel dissimilar kayan; Surface mai rufi waldi na karfe. Nickel-Copper waldi waya ERNiCu-7 Monel 400 gami da kanta waldi; da waldi na Monel 400 gami da karfe; Ana amfani da shi don surfacing na karfe.
