11.2.1 Alnico. Alnico magnets were invented in Japan in the early 1930s. The first compositions did not contain cobalt and were called alni. With the discovery that cobalt enhanced magnetic properties, several compositional variations followed between 1935 and 1974, ending with alnico 9. Alnico is a spinodally-decomposed alloy consisting of two ...Web
