Uses of different types of magnets
November 26, 2021

1. Ndfeb permanent magnet is a modern permanent magnet with strong magnetism. It is also widely used.

The application situation of Ndfeb magnets in China is as follows, the application of high-tech products accounted for 37%, such as Magnetic Resonance Imaging (MRI), mobile phone vibration, hard disk drive voice coil (VCM), optical disk (DVD, CD-ROM) drive spindle, power tools, electric vehicles, variable frequency air conditioning engine.

The application of traditional middle and low grade products accounted for 63%, such as audio devices, magnetic adsorption devices, magnetic separators, magnetizers. In addition, can also be used in toys, packaging boxes, leather products, magnetic jewelry and other fields.

2. Permanent magnet ferrite is used as a constant magnet in electricity meters, generators, telephones, loudspeakers, televisions and microwave devices. It is also used in sound recorders, pickups, loudspeakers, and magnetic cores of various instruments, used in radar, communication, navigation, telemetry and other electronic equipment.

3. Samarium cobalt magnets, which operate at temperatures up to 300 degrees Celsius and are resistant to corrosion and oxidation, are widely used in detectors, generators, radars, instruments and other precision technologies.

4.Aluminum nickel cobalt magnet high temperature resistance, corrosion resistance.

Mainly used in motors, sensors, medical instruments, hand tools, loudspeakers and various instruments.

5.Rubber magnets are divided into same-sex and heterosexual, same-sex suction is relatively weak is mainly used for publicity (refrigerator stickers, car stickers, etc.), decorative gifts, refrigerator magnets, toys, teaching materials and so on.

Oppositely strong magnetic force can be used for small motors, sensors, magnetic adsorption supplies, etc.

It is very important for enterprises to understand the use of different magnets. Taking full advantage of the characteristics of different magnets can better improve product performance.
