Product Detail
Technical Specifications

According to different production processes,alnico magnet is divided into cast alnico magnet and sintered alnico magnet.Compared to the cast alnico magnet,the sintered alnico magnet is limited to a small size,and the resulting blank materials has a dimensional tolerance that is better than that of the cast alnico magnet,and the magnetic properties are slightly lower than the cast alnico magnet,but processability is better.

The shape of the alnico magnet is mostly round and square,but irregular shapes can be customized on request.
The casting process (cast alnico magnet) can be processed into different sizes and shapes.

In permanent magnet material,cast alnico magnets have the lowest reversible temperature coefficient and can operate at temperatures up to 550 ℃.

Characteristics of alnico magnet

1. Crystal density,high strength
2. Stong corrosion resistance
3. Uniform composition,excellent magnetic properities
4. Good temperature stability
5. Maximum working temperature up to 550 ℃

Application of alnico magnet
Quick Die Change System
Electric motors
Electric guitar pickups
Microphones
Sensors
Speakers
Ttraveling wave tubes
Animal husbandry
Teaching equipment

Magnetization orientation of cylnider alnico magnet
Most of cylinder alnico magnet are axial magnetized.But there are some applications that require magnetization of its diametrical direction.
