Excellent quality Sintered AlNiCo magnet:
Sintered Alnico Magnet are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. Among all the available magnetic materials, they feature 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 processes for alnico magnet: Cast and Sintered.
Cast AlNiCo magnet can be made into intricate and complex shapes, which is not possible with other magnetic material. Sintered AlNiCo magnet is manufactured using a powder metallurgy process.
