Aimants Alnico
Alnico magnetic material is an alloy of aluminum-nickel-cobalt which possesses an excellent temperature stability and high residual induction . However, its low coercive force limits its applications in many cases. Casting and sintering are two major processes used to manufacture the Alnico magnets.
Alnico magnets with complex shapes may be manufactured by casting. However, once the Alnico magnets are formed, it is difficult to machine or drill them due to the hard and brittle mechanical properties of Alnico.
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°C. Cast Alnico magnet is widely used in all kinds of sensors and meters, electronics, instruments, medical instruments, teaching, automobile, aviation, martial and other applications.
