Sintered Alnico Magnet are made primarily from aluminum, nickel,
cobalt, copper, iron and sometimes titanium. Among all the available magnetic materials, they have high magnetic flux density, good resistance to corrosion and excellent temperature stability, the maximum working temperature up to 60°c.
There are two different manufacturing process for
alnico magnet: Cast and Sintered.
Cast alnico can be made into intricate and complex shapes, which is not possible with other
magnetic material. Sintered alnico is manufactured using a powder metallurgy process.
