Alnico magnets are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. Among all the available magnetic materials, they have high magnetic flux density, resistance to corrosion and excellent temperature stability, the maximum working temperature up to 600℃. Alnico magnet is widely used in all kinds of sensors and meters, electronics, instruments, medical instruments, teaching, automobile, aviation, martial and other applications.
There are two different manufacturing process for Alnico: Cast and Sintered Alnico. Cast Alnico can be made into intricate and complex shapes, which is not possible with other magnetic materials. Sintered Alnico is manufactured using a powder metallurgy process. while slightly weaker than cast alnico, It exhibits superior mechanical characteristics .
