ABSTRACT

Nickel (Ni) is a versatile metallic element since it is used as a component in hundreds of alloys; it is used as a corrosion-resistant plating product and also as a catalyst. Approximately 61% of the Ni produced worldwide is used in the fabrication of stainless steels, which contain by weight approximately 10% Ni (Nickel Institute 2010). Only about 12% of the world production of Ni is used in the fabrication of Ni-based alloys also called high-Ni alloys. Over 90% of Ni-containing products are recycled at the end or their useful life, and there are no limits on how many times the Ni metal can be recycled (Nickel Institute 2010).
