Cast AlNiCo Magnets (powerful magnet, magnet ring, magnet tiles, block magnets, magnet cylinder, ball magnets , horseshoe magnets)

Alnico magnets are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium, 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. It is high magnetic flux density, resistance to corrosion and excellent temperature stability, the maximum working temperature up to 600℃. Cast Alnico magnet is widely used in all kinds of sensors and meters, electronics, instruments, medical instruments, teaching, automobile, aviation, martial and other applications.
