AlNiCo Magnets The Details Of The Introduction
May 23, 2017

   AlNiCo Magnets Samarium cobalt magnet) also known as samarium cobalt magnet, samarium cobalt permanent magnet, samarium cobalt permanent magnet, rare earth cobalt permanent magnet and so on. Is a magnetic material made of samarium, cobalt and other rare earth materials by the ratio, dissolved into alloy, crushed, pressure type, sintered after a magnetic material, with a high energy product, very low temperature coefficient, the maximum operating temperature Up to 350 ℃, negative temperature is not limited, the working temperature above 180 ℃, and its temperature stability and chemical stability are more than NdFeB permanent magnet materials.

    AlNiCo Magnets Has a strong resistance to corrosion and oxidation resistance; it is widely used in aerospace, defense industry, microwave devices, communications, medical equipment, instruments, instruments, all kinds of magnetic drives, sensors, magnetic processors, motors, magnetic cranes Wait.

    AlNiCo Magnets The samarium cobalt magnet is a kind of rare earth magnet, which is made of samarium, cobalt and other rare earth materials. Developed successfully in 1970, samarium cobalt magnet is now the second strong magnetic magnet, with a high maximum energy product (BHmax), higher coercivity, fragile, easy to crack. The maximum magnetic energy product of the samarium cobalt magnet ranges from 9 MGOe to 31 MGOe. There are two compositions of samarium cobalt, which are 1: 5 and 2:17, respectively (samarium atom: cobalt atom). [22] For example, the maximum energy product of the 2: 17 alloy is 26 MGOe, the coercivity is 9750 oersted, the Curie temperature is 825 ° C and the maximum operating temperature is 350 ° C.

   1. SmCo magnets are easy to peel. When dealing with them, you must wear goggles.

2. Putting the magnets together may cause the magnets to crush, which may cause a potential hazard.

3. SmCo is made from a so-called sintering process, and all materials are sintered and are very likely to produce cracks inside. The magnets do not have mechanical integrity and have only the function of preparing magnetic fields. Therefore, it is necessary to design a special mechanical system to give the overall system sufficient mechanical reliability.

   AlNiCo Magnets Samarium cobalt magnet production process: ingredients → melting ingot → milling → pressure → sintering tempering → magnetic detection → grinding processing → cutting → finished products.

These alloys are usually processed in a non-magnetized state. Smannite with wet grinding (water-cooled heat dissipation) and diamond grinding wheel. This procedure is required if drilling holes or other features are limited. The grinding waste must not be completely dry, because the samarium cobalt has a low ignition point. A small spark, such as the production with static electricity, can be easily burned. The temperature of the fire will be very high and difficult to control.
