Nickel can be deposited soft or hard-dull or bright, depending on process used and conditions employed in plating. Thus, hardness can range from 150–500 Vickers. Can be similar to stainless steel in color, or can be dull gray or light gray (almost white) color. Corrosion resistance is a function of thickness.
