Magnetic materials refer to materials composed of ferromagnetic substances. They are the main materials for motors, electrical appliances, electronics, electroacoustics, optics, instrumentation. Magnetic materials can be divided into soft magnetic materials and hard magnetic materials according to their different properties. In this article, let’s take a look at the advantages and disadvantages of different magnets.
Ferrite magnet is a permanent magnet made mainly from SrO, BaO, and Fe2O3.
The advantages of the ferrite magnets: Ferrite magnets are affordable in price, have good temperature characteristics, and are corrosion-resistant. Therefore, they have a good price-performance ratio.
The disadvantages of the ferrite magnets: Ferrite magnets have weak magnetic force, and are easy to break and drop corners.
The advantages of the NdFeB magnets: NdFeB magnets have the best magnetic properties, good price, good strength, and are easy to process into special shapes.
The disadvantages of the NdFeB magnets: NdFeB magnets are not resistant to high temperature and corrosion, and are fragile.
The advantages of the SmCo magnets: Smco magnets have high heat resistance, good temperature stability, and corrosion resistance.
The disadvantages of the SmCo magnets: Smco magnets are relatively expensive.
The advantages of the aluminum nickel cobalt magnets: Alnico magnets have excellent temperature characteristics and are resistant to corrosion.
The disadvantages of the aluminum nickel cobalt magnets: Alnico magnets have poor interference resistance and are easily magnetized or demagnetized.
The advantages of the rubber magnets: The rubber magnet has good flexibility, can be folded, can be cut, and is resistant to corrosion.
The disadvantages of the rubber magnets: The magnetic properties of the rubber magnet are very weak, and the magnetic force starts to drop at 100°C.
