The difference between AlNiCo magnets and ferrite magnets

Alnico magnets have strong anti-corrosion and anti-oxidation capabilities, and are widely used in aerospace, national defense, microwave devices, communications, medical equipment, instruments, various magnetic transmissions, sensors, magnetic processors, motors, magnetic cranes, etc. . So, what are the differences between alnico magnets and ferrite magnets? Today, let's find out together!

What are the differences between AlNiCo magnets and ferrite magnets?

1. Appearance

Ferrite magnet: Ferrite is soft and non-metallic, generally not electroplated, usually black.

Alnico Magnet: It has a metallic luster and a high density.

2. Magnetic aspects

Ferrite: According to survey data, the magnetic force of ferrite is generally 500-1700 Gauss.

Alnico magnets: Under bare magnetic conditions, the magnetic force of cobalt magnets can reach about 2000 Gauss.

3. Performance

Ferrite magnet: Ferrite has good temperature resistance and stability. Compared with NdFeB, the ordinary temperature resistance is only 80 degrees. And the price is very cheap.

Alnico magnets: Alnico magnets have the characteristics of small size, light weight, and strong magnetism, while magnetism is completely different from ferrite.

4. Expenses

Ferrite: Iron oxides are cheap, and many of them are calculated by the piece. The price is related to the shape, size, and processing difficulty of the ferrite.

AlNiCo magnets: The price of AlNiCo magnets is relatively stable now, depending on the grades you need and special requirements.
