Samarium Cobalt Magnet

Samarium Cobalt Magnet Details

Samarium cobalt magnet is a kind of rare earth magnet. It is a kind of magnetic tool material made from samarium, cobalt and other rare earth metal materials after proportioning, melting and alloying. After crushing, pressing and sintering, it has high magnetic energy product and relatively high magnetic energy. Low temperature coefficient, the highest operating temperature can reach 250-350 degrees Celsius, and there is no limit to negative temperature. When the operating temperature is above 180 degrees Celsius, the samarium cobalt permanent magnet has larger magnetic energy product (BHmax), coercivity (coercivity) and temperature stability The resistance and chemical stability exceed that of NdFeB permanent magnet materials, and it has strong corrosion resistance and oxidation resistance.

Compared with NdFeB magnets, SmCo magnets are more suitable for working in high-temperature environments and are very suitable for manufacturing various high-performance permanent magnet motors and application products with very complex working environments, so they are widely used in aerospace and national defense. Military industry, microwave devices, communications, medical equipment, instruments, meters, various magnetic transmission devices, sensors, magnetic processors, motors, magnetic cranes, etc. The maximum magnetic energy product (BHmax) of samarium cobalt magnets ranges from 16 MGOe to 32 MGOe. Samarium-cobalt permanent magnets have two composition ratios, which are (samarium atoms: cobalt atoms) 1:5 and 2:17.

Samarium Cobalt Magnet Processing
The production process of samarium cobalt magnets: ingredients → smelting and ingot making → powder making → pressing → sintering and tempering → magnetic detection → grinding processing → pin cutting processing → finished product.
These alloys are usually machined in the non-magnetized state, using wet fine grinding (water-cooled heat dissipation) and diamond grinding wheels. This procedure is required if drilling holes or other functional limitations. Grinding waste generation must not be completely dry because samarium cobalt has a low flash point. A small spark, such as one produced with static electricity, can easily burn. The temperatures generated by fires can be very high and difficult to control

Characteristics of samarium cobalt magnets
Samarium cobalt permanent magnets have very good coercivity and good temperature stability.
Samarium cobalt magnets are expensive and susceptible to price fluctuations (the cobalt market is price sensitive).
Samarium cobalt magnets are easily broken. When handling them, safety goggles must be worn.
Letting the magnets bang together can cause the magnets to shatter, which could lead to a potential hazard.
Samarium Cobalt is manufactured by a process called sintering, and as all materials are sintered, cracks are very likely to occur internally. Magnets do not have mechanical integrity and only have the function of preparing a magnetic field. Therefore, special mechanical systems must be designed to give the overall system sufficient mechanical reliability.
