Various uses of Al Ni Co magnets
Al Ni Co magnets are the most powerful permanent magnets among contemporary magnets. Its BHmax value is 5-12 times of that of ferrite magnet, and its coercive force is 5-10 times of that of ferrite magnet. Its potential magnetic property is very high, and it can absorb 640 times of its own weight.
As the main raw material of AlNiCo magnets is iron, which is very cheap, and its resource storage capacity is relatively large, its price is also far lower than that of samarium cobalt magnets. Al Ni Co magnets have better mechanical properties and are easier to cut, drill and process complex shapes. The disadvantage of AlNiCo magnet is its poor temperature performance and high temperature magnetic loss, so it needs to work at low temperature. The temperature is generally about 80 ℃. Specially treated magnets can withstand temperatures up to 200 degrees Celsius. Since the material contains large amounts of neodymium and iron, corrosion is also its weakness. Therefore, AlNiCo magnets must be coated. It can be plated with nickel (nickel), zinc (zinc), gold (gold), chromium (chromium), epoxy resin (epoxy resin), etc.
AlNiCo magnets are widely used in industry, aerospace, electronics, electromechanical, instrumentation, medical and other fields. It has more and more applications in non-technical fields, such as adsorption magnets, toys, jewelry, etc. At present, many manufacturers prefer to choose equipment with such magnets when introducing magnetic field equipment, because such equipment is not only cheaper, but also has better performance in use.
In addition, such magnets can generate relatively strong electromagnetic fields, attracting ferromagnetic chemicals such as iron, nickel, cobalt and other metals while providing magnetic force Constant magnetic field is used in generator sets, telephones, loudspeakers, televisions and microwave heating elements, as well as in recorders, pickups and loudspeakers. It is also used as the magnetic core of various electronic products such as instrument panel, radar detection, communication, navigation bar, monitoring, etc. It is widely used. AlNiCo magnets consist of iron, cobalt, nickel and other atoms. The atom has a relatively unique internal structure and its own magnetic moment. Magnets can generate electromagnetic fields and have the characteristics of attracting ferromagnetic chemicals such as iron, nickel, cobalt and other metals.
Classification of Al Ni Co magnets:
AlNiCo magnets can be classified into lattice magnets, tile magnets, special-shaped magnets, cylindrical magnets, circular magnets, disk magnets, magnetic ring magnets and magnetic frame magnets according to their shapes
Al Ni Co magnets are divided into permanent magnets and magnetic tiles. The combination of permanent magnet and strong magnet modulates the angular momentum of magnetic chemical substances and the momentum of electronic equipment, and the combination of ceramic tile and electricity. (This is also a way to increase the magnetism.) As aluminum, nickel and cobalt are removed by charging and discharging, the magnetism is gradually lost.
