SmCo magnets have strong corrosion resistance and oxidation resistance, and are widely used in aerospace, national defense and military industry, microwave devices, communications, medical equipment, instruments, various magnetic transmission devices, sensors, motors, magnetic cranes and other fields. So, what are the differences between samarium cobalt magnets and ferrite magnets? Today, let's have a look.
Comparison of magnetic differences between ferrite and samarium cobalt magnets:
1、 Appearance
Ferrite magnet: The ferrite is soft and has no metallic luster. It is generally not electroplated and is usually black.
SmCo magnet: It has metallic luster and high density.
2、 Magnetism.
Ferrite: According to the survey data, the magnetic force of ferrite is generally 500-1700 gauss.
Samarium cobalt magnet: under the bare magnetic condition, the magnetic force of cobalt magnet can reach about 2000 gauss.
3、 Performance.
Ferrite magnet: Ferrite has good temperature resistance and stability. Compared with neodymium iron boron, ordinary temperature resistance is only 80 degrees. And the price is very cheap.
SmCo magnet: SmCo magnet has the characteristics of small size, light weight and strong magnetism, while magnetism is completely different from ferrite.

4、 Cost.
Ferrite: The price of iron oxide is cheap, many of which are calculated by pieces, and the price is related to the shape, size and processing difficulty of ferrite.
Samarium cobalt magnet: The price of Samarium cobalt magnet is relatively stable now, which depends on the brand and special requirements you need.
5、 Advantages and disadvantages.
Advantages of ferrite: The advantages of ferrite are high permeability, low price, temperature resistance, suitable for low-frequency occasions!
Defect of ferrite: poor magnetism.
Advantages of samarium cobalt magnet: strong magnetism, high cost performance, high temperature resistance, wide use, corrosion resistance, strong oxidation resistance.
Disadvantages of samarium cobalt magnet: fragile and easily damaged.
