Noun
trade name for an alloy used to make high-energy permanent magnets; contains aluminum and iron and nickel plus cobalt or copper or titanium

The tube is embraced between the poles of two horseshoe-shaped alnico magnets (top, bottom), which create a magnetic field along the axis of the tube. Source: Internet
Alnico was used almost exclusively until about 1980. Source: Internet
When high field-strength permanent magnets became available, Alnico, an alloy of aluminum, nickel, and cobalt became popular, since it dispensed with the power supply problems of field-coil drivers. Source: Internet
Metallic iron and the alloy alnico are examples of ferromagnetic materials involving transition metals. Source: Internet
The maximum usable temperature is highest for alnico magnets at over convert, around convert for ferrite and SmCo, about convert for NIB and lower for flexible ceramics, but the exact numbers depend on the grade of material. Source: Internet
