Lateritic nickel ore deposits - Wikipedia

Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite, peridotite and komatiite and their serpentinized derivatives, serpentinite which consist largely of the magnesium silicate serpentine and contains approx. 0.3% nickel.

Properties and applications of electroless nickel

The magnetic properties of electroless nickel are of ex-treme importance as they have been responsible for one of the single largest applications for high phosphorus deposits, i.e. as an underlayer for magnetic coatings in the production of memory discs. The magnetic response of electroless nickel varies greatly with phosphorus content, as shown in Figure 5.4 The ferromagnetism associated with ...

Chapter 2 Magnetic Materials and Their Characteristics

investigated nickel-iron alloys as early as 1889, it was not until the studies by Elmen, starting in about 1913, on properties in weak magnetic fields and effects of heat-treatments, that the importance of the Ni-Fe alloys was realized. Elmen called his Ni-Fe alloys, "Permalloys," and his first patent was filed in 1916. His preferred composition was the 78Ni-Fe alloy. Shortly after Elmen ...
