  2. Alnico - Wikipedia

    en.wikipedia.org/wiki/Alnico

    The composition of alnico alloys is typically 8–12% Al, 15–26% Ni, 5–24% Co, up to 6% Cu, up to 1% Ti, and the rest is Fe. The development of alnico began in 1931, when T. Mishima in Japan discovered that an alloy of iron, nickel, and aluminum had a coercivity of 400 oersteds (32 kA/m), double that of the best magnet steels of the time.

  7. Nickel aluminide - Wikipedia

    en.wikipedia.org/wiki/Nickel_aluminide

    Nickel aluminide refers to either of two widely used intermetallic compounds, Ni 3 Al or NiAl, but the term is sometimes used to refer to any nickel–aluminium alloy. These alloys are widely used because of their high strength even at high temperature, low density, corrosion resistance, and ease of production. [1]

  8. Raney nickel - Wikipedia

    en.wikipedia.org/wiki/Raney_nickel

    The NiAl alloy is prepared by dissolving nickel in molten aluminium followed by cooling ("quenching"). Depending on the Ni:Al ratio, quenching produces a number of different phases. During the quenching procedure, small amounts of a third metal, such as zinc or chromium, are added to enhance the activity of the resulting catalyst.
