Various uses of aluminum nickel cobalt magnets


Aluminum nickel cobalt magnets are more powerful permanent magnets in contemporary magnets. Its BHMAX value is 5-12 times that of iron oxygen magnets, and its stubborn force is 5-10 times that of iron oxygen magnets. Its potential magnetism is very high and can absorb 640 times the energy of its own weight.

Because the main raw material iron of aluminum nickel cobalt magnet is very cheap and the resource storage capacity is relatively large, its price is much lower than that of a cobalt magnet. Aluminum nickel cobalt magnets have better mechanical properties, and are easier to cut, drill and process complex shapes. The disadvantage of aluminum nickel cobalt magnets is poor temperature performance and high magnetic loss at high temperature, so it is necessary to work in a low temperature environment. The temperature is generally about 80 degrees Celsius. The temperature that can be affected by specially processed magnetic work can reach 200 degrees Celsius. Because the material contains a large amount of ravioli and iron, it is also its weakness. Therefore, the aluminum nickel cobalt magnet must be coated. It can electroplating nickel (nickel), zinc (zinc), gold (gold), chromium (chromium), epoxy resin (epoxy resin), etc.

Classification of aluminum nickel cobalt magnet:

Aluminum nickel cobalt magnet classification is classified by shape: can be divided into dot matrix magnets, tile magnets, album -shaped magnets, cylindrical magnets, round magnets, disc magnetic ring magnets, magnetic ring magnets, and magnetic frame magnets

Aluminum nickel cobalt magnets are divided into permanent magnets and magnetic tiles. The permanent magnet and the strong magnetic body are combined to regulate the angular momentum of the magnetic chemical and the amount of electronic equipment. (This is also a method that increases magnetism.) When removing aluminum, nickel and cobalt by charging and discharging, magnetism will gradually lose.


Aluminum nickel cobalt magnets are widely used in industrial, aerospace, electronics, electromechanical, instrumentation, medical care and other fields. Non -technical fields are more and more widely used, such as adsorption magnets, toys, jewelry, etc. At present, many manufacturers will prefer to choose equipment with such magnets when introducing magnetic field equipment, because such equipment is not only cheaper, but also the main thing is that the performance is also better.

In addition, this magnet can produce a relatively powerful electromagnetic field. While supplying magnetic power while providing magnetic chemicals such as iron, nickel, cobalt, and other metals, it is often used as an electrical meter. , The constant magnetic field of the generator, telephone, speaker, TV, and microwave heating components, and is also often used for recorders, pickups and speakers. It is also used for various instrument panels, radar detection, communication, navigation strips, monitoring and other magnetic cores, which are widely used. The ingredients of aluminum nickel and cobalt are iron, cobalt, nickel and other atoms. The internal structure of the atom is relatively unique and has its own magnetic moment. Magnetic can produce electromagnetic fields and has the characteristics of attracting iron magnetic chemicals such as iron, nickel, cobalt, and other metals.
