Advantages and Applications of Sintered AlNiCo Magnets

After being discovered by Tokushichi Mishima in 1931, AlNiCo magnets have received a lot of attention. Due to their many advantages, AlNiCo magnets still occupy an important position in the applications of permanent magnets. According to different production processes, ALNICO Magnets can be divided into Sintered AlNiCo Magnets and Cast AlNiCo Magnets. In this article, let's take a look at the advantages and applications of Sintered AlNiCo Magnets. 

Advantages and Applications of Sintered AlNiCo Magnets

Before diving into our article, let's take a look at the manufacturing process of sintered AlNiCo magnets. Compared with Cast AlNiCo magnets, the magnetic properties of Sintered AlNiCo magnets are lower, but the manufacturing process of Sintered AlNiCo magnets is simpler. 

Manufacturing Process of Sintered AlNiCo Magnets

Advantages of Sintered AlNiCo Magnets

1. The use temperature of the Sintered AlNiCo magnets can be as high as 450-500 degrees Celsius. Besides, they come with a small magnetic output change and temperature change among the permanent magnets.
2. Although the magnetic properties of sintered AlNiCo magnets are slightly lower than those of the cast AlNiCo magnets, their mechanical properties are much better.
3. The size and dimensional tolerances of Sintered AlNiCo Magnets are relatively smaller than those of cast magnets and do not require much further processing.
4. Sintered AlNiCo Magnets are suitable for mass production.
5. Sintered AlNiCo Magnets have excellent corrosion resistance.

Applications of Sintered AlNiCo Magnets

Alnico permanent magnets are mainly composed of aluminum, nickel, cobalt, iron, copper, titanium, and other materials. Newly developed application areas of AlNiCo magnets: Hall components for temperature sensors and electronic sensors for automobiles. Traditional applications of Alnico Magnets include magnetrons, TWT amplifiers, regulators, motors, and meters.  Rare earth permanent magnets have replaced Alnico magnets in many application fields.
