Aluminum cobalt magnets are permanent magnets with powerful function in contemporary magnets. Its BHMAX value is 5-12 times that of iron oxygen magnets, and the stubborn force is 5-10 times that of the iron oxygen magnet. The potential magnetability is high and can absorb the energy of 640 times itself.
Because the main raw material iron of the AL-NI-Co magnet is very cheap and its own resource storage is relatively large, the price is far lower than the mandalacular magnet. The mechanical properties of nickel -cobalt magnets are better, and it is easier to cut, drill and process complex shapes. The disadvantage of nickel -cobalt magnetism is poor temperature performance, high magnetic loss at high temperature, and needs to work at low temperature. The temperature is generally about 80 degrees Celsius. The specially processed magnets can work at a temperature of up to 200 degrees Celsius. Because this material contains a large amount of ravioli and iron, its corrosiveness is also its weakness. Therefore, aluminum -nickel cobalt magnets must be coated. Can electroplating nickel (nickel), zinc (zinc), gold (gold), chromium (chromium), epoxy resin (epoxy resin), etc.
Nickel cobalt magnets are widely used in industrial, aerospace, electronics, electrical, electromechanical, instrumentation, medical and other fields. Non -technical applications are becoming more and more extensive, such as adsorption magnets, toys, jewelry, etc. At present, many manufacturers will prefer this magnetic device when introducing magnetic field equipment, because such equipment is not only cheaper, but more importantly, it is better in use.
In addition, magnets like this can produce strong electromagnetic fields, which can provide magnetic power, and at the same time, it has the characteristic function of attracting ferromagnetic chemicals such as iron, nickel, and cobalt. In addition, it is often used as a meter, generator set, telephone, speaker, TV and microwave heating components, and a constant magnetic field of recorder, pickup truck and speaker. It is also used as a magnetic core for various electronic products, such as instrument panels, radar detection, communication, navigation bar, monitoring, etc. And widely used. The ingredients of aluminum cobalt magnet 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 metal such as iron, nickel, and cobalt.
Classification of Nickel Cobalt Magnetic:
Nickel cobalt magnets are classified by shape: dot matrix magnets, tile -shaped magnets, alien magnets, cylindrical magnets, circular magnets, disc fingles, magnetic ring magnets, magnetic frame magnets.
Aluminum cobalt magnets are divided into permanent magnets and magnetic tiles. A binding of permanent magnets and strong magnets, regulating the angular momentum of magnetic chemicals and the amount of electronic equipment, binding tiles and electrical. (This is also a way to increase magneticity.) When aluminum, nickel, and cobalt are removed by charging, magneticity will gradually lose.
