Alnico magnets are highly coercive and have a high Curie temperature. Alnico magnets, on the other hand, are hard and brittle and cannot be cold worked. They must be created through casting or sintering processes.
Alnico magnets can produce magnetic fields of up to 0.15 Tesla. As an example, consider an intermediate anisotropic cast aluminum-nickel-cobalt alloy. Alnico-6 is composed of 8% Al, 16% Ni, 24% Co, 3% Cu, 1% Ti, and the rest are all Fe. The maximum BHmax of Alnico-6 is 3.9MGOe, the coercivity is 780 oersteds, the Curie temperature is 860 °C, and the maximum operating temperature is 525 °C.
