Nickel and Nickel alloys have many applications. This element gives alloys stainless properties and good creep resistance (INOX; INVAR/KOVAR, Phynox, etc.), but Nickel is also used to obtain alloys with low coefficients of thermal expansion (Cunife, Fernico) widely used in the aeronautics, permanent magnets (AlNiCo), in jewelery (Au-Ni)…
