Nickel is a metal which is mainly used as an alloying element of stainless steel, major ingredient of brass, and for electroplating. Nickel is also used together with lanthanum in the nickel metal hydrid (NiMH) battery.[1] Nickel is highly resistant to corrosion and is widely used to create corrosion resistant alloys and is also used heavily in the electroplating process. Nickel is used with Chromium to create Nichrome, which has a high melting point and is used for the efficient conversion of electricity to heat. Annual world production was 1.4 million tonnes in 2007
