Long strip-shaped samarium cobalt magnet

Samarium cobalt magnet is a rare earth magnet made by blending samarium, cobalt, and other rare earth materials into alloys, which are then crushed, pressed, and sintered to produce a magnetic tool material. It has a high magnetic energy product, low temperature coefficient, and can work at high temperatures up to 250-350 degrees Celsius, with no limit to negative temperature. When the working temperature is above 180 ℃, samarium cobalt permanent magnets have a larger magnetic energy product, coercivity, temperature stability, and chemical stability than neodymium iron boron permanent magnetic materials, and 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 well suited for manufacturing various high-performance permanent magnet motors and applications with complex working environments. Therefore, they are widely used in aerospace, defense and military industries, 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, namely (samarium atom: cobalt atom) 1:5 and 2:17.

Samarium cobalt magnet processing
Production process of samarium cobalt magnets: ingredients → smelting and ingot making → powder making → pressing → sintering and tempering → magnetic testing → grinding processing → cutting processing → finished product.
These alloys are typically processed in a non-magnetic state using wet fine grinding (water-cooled heat dissipation) and diamond grinding wheels for samarium cobalt. This process is necessary if there are limitations in drilling or other functions. Grinding waste must not be completely dried because samarium cobalt has a low ignition point. A small spark, if produced with static electricity, can easily burn. The temperature generated by a fire can be very high and difficult to control.



Characteristics of Samarium Cobalt Magnet
Samarium cobalt permanent magnets have excellent coercivity and good temperature stability.
Samarium cobalt magnets are expensive and susceptible to price fluctuations (cobalt market prices are sensitive).
Samarium cobalt magnets are easily peeled off. When handling them, goggles must be worn.
Colliding magnets together may cause them to shatter, which could pose a potential danger.
The manufacturing of samarium cobalt involves a process called sintering, which involves sintering all materials and is highly likely to produce cracks inside. Magnets do not have mechanical integrity and only have the function of preparing magnetic fields. Therefore, special mechanical systems must be designed to provide sufficient mechanical reliability to the overall system.
