I-alloy 625 (i-UNS N06625) i-alloy ye-nickel-chromium-molybdenum kunye nokongezwa kwe-niobium. Ukongezwa kwezenzo ze-molybdenum kunye ne-niobium ukuqinisa i-matrix ye-alloy, ukubonelela amandla aphezulu ngaphandle kokuqiniswa kwonyango lokushisa. I-alloy imelana noluhlu olubanzi lweendawo ezidliwayo kwaye inokumelana kakuhle ne-pitting kunye ne-crevice corrosion. I-alloy 625 isetyenziselwa ukusetyenzwa kweekhemikhali, i-aerospace kunye ne-oyile yobunjineli baselwandle kunye negesi, izixhobo zokulawula ungcoliseko kunye nezixhobo zenyukliya.
