Alnico is an acronym referring to a family of iron alloys, which is composed primarily of aluminum (Al), nickel (Ni) and cobalt (Co) with small amounts of copper and titanium. Alnico alloys are produced by casting or sintering processes. Alnico alloys are ferromagnetic, with low coercivity. Alnico resistance of magnetism varies by grade from 630 to 1880 oersteds, and is used to make permanent magnets. The composition of alnico alloys is typically 12%-Al, 26%-Ni, 24%-Co, 6%-Cu and 1%-Ti, and the iron. Alnico magnets produces a magnetic field strength at their poles that are as high as 0.15 teslas or about 3000 times the strength of Earth’s magnetic field. Alnico alloys can be magnetized to produce strong magnetic fields and have a high resistance to demagnetization, thus making strong permanent magnets.

Alnico magnets are used in electric motors and various sound systems such as microphones and loudspeakers. Presently, alnico magnets are replaced by rare-earth magnets such as neodymium and samarium-cobalt magnets. Alnico is a hard ferromagnetic substance, which is broadly employed in temperature sensitive applications such as hall-effect and MR-based electronic and automotive sensors. Presence of strong substitutes such as neodymium magnets and samarium-cobalt magnets is anticipated to hamper the overall demand for alnico during the forecast period.
