L′aimant Alnico en fonte

Alnico magnet is a kind of alloy consisting primarily of iron, aluminum, nickel, cobalt, with minor amounts of other elements including copper and titanium. Alnico magnet alloy is a mature technology and is manufactured by casting or sintering. Cast Alnico magnet is produced by conventional foundry methods using resin bonded sand molds, it is suitable for complex geometries and configurations not achievable with other magnet materials. Cast Alnico can be tailored easily to obtain a variety of magnetic properties and characteristics. Specialized casting techniques are used to achieve the unique crystalline grain orientation found in Alnico 5-7(LNG60). Sintered Alnico magnet is produce by powder metallurgy. Shaped by dry powder press, sintered in Vacuum sintering furnance. Both Cast Alnico and sintered Alnico's property are optimized during a heat treatment process which is unique to Alnico.
