Uma i-metal foundry iphonsa i-nickel esekelwe i-alloy ngokulahlekelwa kwe-investimenti ye-wax casting (uhlobo lwe-precision casting) inqubo, khona-ke kuzotholwa utshalomali lwe-nickel alloy. Ingxubevange esekelwe ku-nickel iwuhlobo lwe-alloy ephezulu ene-nickel njenge-matrix (ngokuvamile enkulu kuno-50%) kanye nethusi, i-molybdenum, i-chromium nezinye izakhi njengama-alloying elements. Izakhi eziyinhloko ze-alloy ye-nickel-based alloys yi-chromium, i-tungsten, i-molybdenum, i-cobalt, i-aluminium, i-titanium, i-boron, i-zirconium njalonjalo. Phakathi kwazo, i-Cr, i-Al, njll. ikakhulukazi idlala umphumela we-anti-oxidation, futhi ezinye izakhi zinokuqiniswa kwesisombululo esiqinile, ukuqinisa imvula kanye nokuqinisa umngcele wokusanhlamvu. Ama-alloys asekelwe ku-nickel ngokuvamile anesakhiwo se-austenitic. Esimweni sesisombululo esiqinile kanye nokwelashwa kokuguga, kukhona nezigaba ze-intermetallic kanye ne-carbonitrides yensimbi ku-matrix ye-austenite kanye nemingcele yokusanhlamvu ye-alloy. Ama-alloys asekelwe ku-nickel anamandla aphezulu kanye nokumelana okuhle kwe-oxidation, ukumelana nokugqwala nokumelana nokushisa okuphezulu ebangeni lika-650 kuya ku-1000°C. Ingxubevange esekelwe ku-nickel iyingxubevange evamile yokumelana nezinga lokushisa eliphezulu. Ama-alloys asekelwe ku-nickel ahlukaniswe abe ama-alloys asekela ukushisisa asuselwa ku-nickel, ama-alloys amelana nokugqwala asuselwa ku-nickel, ama-alloy angagugi asuselwa ku-nickel, ama-alloys asuselwe ku-nickel ngokunemba kanye nama-alloys enkumbulo asuselwa ku-nickel ngokuya ngezakhiwo zawo eziyinhloko. Ama-superalloy asekelwe ku-nickel, ama-superalloy asekelwe ku-iron nama-superalloy asekelwe ku-nickel abizwa ngokuhlanganyela njengama-alloys aphezulu okushisa. Ngakho-ke, ama-superalloys asekelwe ku-nickel abizwa ngokuthi ama-alloys asekelwe ku-nickel. Izinto zochungechunge lwe-nickel-based superalloy zisetshenziswa kabanzi kwezokundiza, i-aerospace, i-petroleum, amakhemikhali, amandla enuzi, i-metallurgy, olwandle, ukuvikelwa kwemvelo, imishini, i-electronics neminye imikhakha. Amamaki kanye nezindlela zokwelapha ukushisa ezikhethelwe izingxenye ezihlukene zemishini zizohluka.
