Alnico process description:
Alnico divided according to the different production processes sintered Alnico (Sintered AlNiCo) and cast Alnico (Cast AlNiCo). Products are mostly round and square shapes. Casting process can be processed into different sizes and shapes; compared with the casting process, sintered products limited to a small size, their production out of the rough dimensional tolerances better than the rough casting products, magnetic products to be slightly lower than the casting, but better workability. In the permanent magnet material, the cast Alnico magnet has a reversible temperature coefficient of the lowest operating temperature of up to 600 degrees Celsius. Alnico magnet products are widely used in various instruments and other applications.
Advantages Alnico magnet system is remanence high (up to 1.35T), low temperature coefficient. Temperature coefficient of -0.02% / ℃, while the maximum temperature up to about 520 ℃. Disadvantages coercivity when very low (typically less than 160kA / m), non-linear demagnetization curve. Therefore, although easy alnico magnet is magnetized, is also likely to demagnetization.
