Alnico was developed in the 1930's and made commercially available in the 1940's. It is an alloy of aluminum, nickel, cobalt and iron. Different grades of Alnico also contain other elements to enhance the magnetic properties. Alnico magnets are either made by casting molten alloy or pressing and sintering a very fine powder. Both can be cut and ground to precision sizes with the proper equipment.
