Loaʻa i ka Nickel ke kūpaʻa kemika kiʻekiʻe a me ke kūpaʻa corrosion maikaʻi i nā media he nui. ʻO kona kūlana electrode maʻamau ʻo -0.25V, ʻoi aku ka maikaʻi ma mua o ka hao a me ka maikaʻi ʻole ma mua o ka copper.Nickel hōʻike i ke kūpaʻa corrosion maikaʻi i ka ʻole o ka oxygen dissolved i nā waiwai non-oxidized dilute (eg, HCU, H2SO4), ʻoi aku i nā hopena kūlohelohe a me ka alkaline. . ʻO kēia no ka mea hiki i ka nickel ke passivate, e hana ana i kahi kiʻiʻoniʻoni pale nui ma luna o ka ʻili, ka mea e pale ai i ka nickel mai ka oxidation hou.
