Samarium cobalt magnet is a kind of rare earth magnet, which is a kind of magnetic tool material made of samarium, cobalt and other metal rare earth materials after proportioning, melting and refining into alloy, crushing, molding and sintering. It has high magnetic energy product, low temperature coefficient, high working temperature of 250-350 ℃, unlimited negative temperature. When the working temperature is above 180 ℃, samarium cobalt permanent magnet has large magnetic energy product (BHmax) The coercivity, temperature stability and chemical stability are better than those of Nd-Fe-B permanent magnet materials, which have strong corrosion resistance and oxidation resistance.

Compared with neodymium iron boron magnets, samarium cobalt magnets are more suitable for working in high-temperature environments, and are very suitable for manufacturing all kinds of high-performance permanent magnet motors and application products with complex working environments. Therefore, they are widely used in aerospace, national defense and military industry, microwave devices, communications, medical equipment, instruments, meters, various magnetic transmission devices, sensors, magnetic processors, motors, magnetic cranes, etc. The large magnetic energy product (BHmax) of samarium cobalt magnets ranges from 16 mgoe to 32 mgoe. Samarium cobalt permanent magnets have two composition ratios, namely (samarium atom: cobalt atom) 1:5 and 2:17.

Samarium cobalt magnet processing
Production process of samarium cobalt magnet: batching → smelting and ingoting → milling → molding → sintering and tempering → magnetic testing → grinding → pin cutting → finished products.
These alloys are usually processed in non magnetized state. Samarium cobalt is used for wet fine grinding (water-cooled heat dissipation) and diamond grinding wheel. This process is required if drilling holes or other functions are limited. Grinding waste must not be completely dry, because samarium cobalt has a low ignition point. A small spark, such as production with static electricity, can easily burn. The temperature caused by fire will be very high and difficult to control.

Samarium cobalt magnet features
Samarium cobalt permanent magnets have very good coercivity and good temperature stability.
Samarium cobalt magnets are expensive and vulnerable to price fluctuations (cobalt market is price sensitive).
Samarium cobalt magnets peel easily. Goggles must be worn when handling them.
Striking the magnets together may cause the magnets to shatter, which may lead to potential danger.
Samarium cobalt is manufactured by a process called sintering, and all materials are sintered. Cracks are very likely to occur inside. The magnet has no mechanical integrity, only the function of preparing magnetic field. Therefore, special mechanical systems must be designed to give the overall system sufficient mechanical reliability.
