Aluminum Nickel Cobalt Magnets are divided into cast Alnico magnets and sintered Alnico magnets according to different production processes. The shapes of the products are mostly round and square. The casting process can be processed into different sizes and shapes; compared with the casting process, the sintered product is limited to a smaller size, and the dimensional tolerance of the formed blank is better than that of the cast product, and the magnetic properties are better than that of the cast product The magnetic properties are slightly lower, but the machinability is better. Among permanent magnet materials, cast Aluminum Nickel Cobalt Magnets have the lowest reversible temperature coefficient and can work at temperatures up to 550 degrees Celsius.

1. Manufacturing process of sintered alnico magnets
2. Advantages of sintered alnico magnets 0824-1
A. Sintered AlNiCo magnets can be used up to 450-500 degrees C, and it has small magnetic output variation and temperature variation between permanent magnet series.
B. Although the magnetic properties of sintered AlNiCo magnets are slightly lower than those of cast AlNiCo magnets, their mechanical properties are much better.
C. The dimensions and dimensional tolerances of sintered alnico are relatively smaller than cast magnets and do not require much further processing.
D. Suitable for mass production.
E. Excellent anti-corrosion ability.

3. Application of Aluminum Nickel Cobalt Magnets
Alnico permanent magnet materials are mainly composed of aluminum, nickel, cobalt, iron, copper, titanium and other materials.
Newly developed application fields of Alnico permanent magnet materials: Hall components of temperature sensors and electronic sensors for automobiles;
Traditional applications are: magnetrons, TWT amplifiers, regulators, motors and instruments;
Rare earth permanent magnet materials have replaced Alnico permanent magnet materials in many application fields.
