Nickel alloys are some of the few metallic materials that can be used in contact with fluorine, hydrofluoric acid, hydrogen fluorine, or other derivatives. Nickel bars show very high resistance to caustic alkalies. Behavior in seawater is also excellent, with improved resistance to cavitation corrosion compared to copper-based alloys. It can be used in contact with dilute solutions of mineral acids, such as sulphuric and hydrochloric acids, particularly if they are air-free. However, if the alloy contains no chromium, corrosion rates may increase significantly in oxidizing conditions.
