CAST AND SINTERED ALNICO MAGNETS
Alnico magnets, whose composition is based on aluminium, nickel and cobalt alloys, are magnets which, despite possessing a high energy product, good remanence and excellent physical characteristics, do not reach the same coercivity values as rare earth magnets. The advantage offered by these magnets, with respect to any other typology, is their high-stability under any temperature conditions.
Cast alnico magnets are the only magnets that are produced in foundries, as can be inferred by their name, and, as such, can take on a vast number of shapes, from the common horseshoe to diamonds, rings or plates.
Sintered alnico magnets, like other sintered magnets, are subjected to a different production cycle.
Given their intrinsic consistency, alnico magnets are naturally utilized in all magnetic applications which require precision: tacho-generators, clocks, scales and precision magnetic instruments.
Alnico magnets are also utilized in the production of magnetic plates and sorters.
Other common uses for this type of magnet include both military (tracking systems and radar) and civilian (railway or power plant instrumentation) applications.
