Magnetic Materials > Alnico Magnets

First used in the 1930’s, Alnico is the oldest family of permanent magnets. With energy products ranging from 1.3 to 10.1 MGOe, Alnico can be produced in both cast and sintered forms. The most common grades are cast Alnico 5 and 8 with Alnico 5-7 and 9 being premium grades. Sintered Alnico materials are used in applications where the geometries are smaller and more complex. 


Alnico magnets are easy to magnetize and have high resistance to corrosion. They are used where high temperatures exist and/or where very stable properties are required.
