Nika-e hāngai ana waea fehokotaki'anga he pai te mahi o te ātete ki te hau kaha, reo caustic, te waikura ātete ki te whakaiti reo waikawa, me te kaha teitei, plasticity pai, matao me te wera deformation me te tukatuka me te fehokotaki'anga āhuatanga, no reira, whakamahia whānuitia i roto i te petrochemical, metallurgy, pūngao ngota, whanaketanga moana, rererangi, Aerospace me etahi atu ahumahi, ki te whakaoti i te whanui kowiri tira me etahi atu konganuku, kaore e taea e nga taonga kore-whakarewa te whakaoti i te raru o te miihini miihini, he tino nui te waikura-ātete rauemi whakarewa. Ko nga koranu-a-nikel e tohu ana ki nga koranu e hangai ana ki te nickel me nga huānga whakakotahi ka taea te aukati i te waikura i etahi o nga papaaho. Ina whakarōpūtia e tona hanganga matū, ko te nuinga o te nickel, nickel-conpara alloys, nickel-molybdenum (nickel-molybdenum ferrolybdenum) alloys, nickel-chromium (nickel-chromium-rino) alloys, nickel-chromium-molybdenum (tae atu ki te nickel-chromium) - molybdenum alloys me te nickel-chromium-molybdenum koranu parahi) me te chromium nickel-rino (e rua nga koranu rino-nickel) me etahi atu waahanga. Ka whakamahia te waea nickel parakore ERNi-1 ki te weld 200, 201 nickel alloy me te nickel-plated steel plate; fehokotaki'anga o te maitai me te nickel rauemi rerekē; Whakakikoruatia te mata o te maitai. Nika-parahi waea fehokotaki'anga ERNiCu-7 Monel 400 koranu ano fehokotaki'anga; me te whakapiringa o Monel 400 me te maitai; Ka whakamahia mo te whakarewanga o te rino. Nichrome waea fehokotaki'anga ERNiCrFe-3 Kei te whakamahia mo te fehokotaki'anga rauemi rerekē o hononga ngokingoki-ātete; – Ko te weriweri o austenitic, maitai ferritic me nga koranu nickel teitei, te whakapiri i nga tira koranu kei roto 9% nickel Nichrome waea whakapiringa ERNiCrFe-7 e whakamahia ana mo te whakarewa i nga koranu me te whakarewa i te mata o te maitai, he mea tino pai mo te hanga i nga reactors karihi. Te whakapiri i te waea nickel-chromium-molybdenum ERNiCrMo-3 INCONEL625, INCONEL825, INCONEL25-6Mo me te MONEL400; – Fehokotaki'anga i waenganui i ultra-high kaha austenitic maitai me INCOLOY020 koranu; Fehokotaki'anga i waenganui i koranu hanga-nika me te kowiri tira rauemi rerekē; Maamaa o te maitai
