I-alloy esekelwe kwi-nickel ibhekisela kwi-alloy ephezulu ene-nickel njenge-matrix (ngokubanzi ngaphezu kwe-50%) kunye ne-copper, i-molybdenum, i-chromium kunye nezinye izinto njenge-alloying elements. Izinto eziphambili ze-alloying ze-nickel-based alloys ziyi-chromium, i-tungsten, i-molybdenum, i-cobalt, i-aluminium, i-titanium, i-boron, i-zirconium kunye nokunye. Phakathi kwabo, i-Cr, i-Al, njl. I-alloys esekelwe kwi-nickel ininzi inesakhiwo se-austenitic. Kwimeko yesisombululo esiqinileyo kunye nokuguga, kukho izigaba ze-intermetallic kunye ne-carbonitrides yensimbi kwi-matrix ye-austenite kunye nemida yeenkozo ze-alloy.I-alloys esekelwe kwi-nickel ngokubanzi iphonswa ngenkqubo yokutshala imali. Amanqanaba aqhelekileyo e-nickel-based alloys yokuphosa ami ngolu hlobo lulandelayo:
- 1) Ni-Cr-Mo ingxubevange, Hastelloy series C-276, C-22, C-2000, C-4, B-3
- 2) I-alloy ye-Ni-Cr: I-Inconel 600, i-Inconel 601, i-Inconel 625, i-Inconel 718, i-Inconel X 750, i-Incoloy 800, i-Incoloy 800H, i-Inconel 800HT, i-Incoloy 825;
- 3) Ni-Cu ingxubevange, Monel 400, Monel K500
