Nickel is a slightly yellow silver white metal, which is a transition metal with ferromagnetism. Electrolytic nickel is nickel made by electrolysis. Stainless steel and various alloy steels made from it are widely used in aircraft, tanks, ships, radars, missiles, spacecraft and some manufacturing in civil industry, ceramic pigments, permanent magnet materials, electronic remote control and other fields.
