Samarium-Cobalt (SmCo) rare earth permanent magnets
SmCo magnets are manufactured with sintering or compression bonding. They are anisotropic and can only be magnetized in the direction of orientation. In general, magnetizing fields of approximately 30KOe to 45KOe are required to saturate SmCo magnets. There are two types for alloy materials, 1:5 and 2:17.
Characteristics:
1.High magnetic properties The intrinsic coercive force could reach up to 22KOe.
2.Low temperature coefficient For some materials, ¦Á could reach low to -0.01% of Br/¡ãC.
3.High working temperature SmCo The maximum recommended working temperature is 250¡ãC(480¡ãF) for SmCo 1:5 and 350¡ãC(660¡ãF) for SmCo 2:17. The Curie Temperature could reach high to 750¡ãC(1390¡ãF) for SmCo 1:5 and 850¡ãC(1560¡ãF) for SmCo 2:17.
4.High resistance to corrosion No coating is needed for surface protection. .
Common applications
High performance motors, Magnetic couplings, Magnetic separators, Aerospace defense, Magnistors, Instruments and meters
SmCo is also named with SmCo magnetic steel, SmCo permanent magnet, SmCo permanent magnetic iron and rare-earth cobalt permanent magnet. It"s a high performance,low temperature coefficient permanent magnet with its high working temperature-350 degree centigrade. When working above 180 degree centigrade, its maximum energy product BH and steady temperature are superior than NdFeB magnetic materials. It needn"t to be coated because it is difficult to be eroded and oxidized. SmCo magnet is widely used in motors, watch,transducers, instruments,positional detector,generators,radar communications,medical equipments, various magnetism spreading devices, magnetic processor,electrical engineering and magnetic derrick.
We supply all kinds and all types of SmCo which feature from XG16-XGS32M. Shape: ring, disc, block, segment, etc.
1. Samarium Cobalt magnets is made of samarium as rare earth elements and cobalt. 2. They have very good magnetic properties, high coercivity and excellent resistance to corrosion. 3. These magnets are best used under highly critical conditions.
Smco magnet is a high-capacity permanent magnet made from sm, co, fe and other trace metal elements. Besides a markable resistance against corrosion and oxidation. Hence, it may be used in aeronautic and space industries among others.
Features: 1.High performance 2.Excellent thermal stability 3.Good stability of the maximum energy product-bh temperature and chemical 4.Strong anti-corrision and oxidation resistance
1. SmCo1:5: SmCo1:5 magnet is also named SmCo5.Prorated with metallic samarium, cobalt and metallic praseodymium , are firstly those roughcasts with different properties and grades after series technology processing from melting, milling, and pressing to sintering in order. The (BH) max range is from 16 to 25, maximum working temperature 250¡ãC. The physical character and ductibility of SmCo5 is better than Sm2Co17, so SmCo5 is slightly easier to be machined thin thickness disc or ring wall and complex shapes while Sm2Co17 is more brittle. Magnetization magnetic field of SmCo5 is lower than Sm2Co17s. In general, SmCo5 can be magnetized saturated by 4000Gs magnetic field, however, magnetizing Sm2Co17 with high Hcj value need more than 6000Gs magnetic field. These days, prices of rare earth materials improved significantly, and the level of rare earth material around the magnet is up to 40%. For these reasons, the price of SmCo5 is more expensive than Sm2Co17. According to different using circumstance, customer can choose SmCo5 or Sm2Co17 reasonably. If customers need more details about SmCo5, please contact our technical adviser in Service and Support. For more information of SmCo5 grade date, please check the SmCo Magnet Performance Parameter Table. Physical properties please tap Application Technology. 2. 17 SmCo magnet: SmCo2:17 magnet is also named Sm2Co17. Prorated with metallic samarium, cobalt, Copper, iron and zirconium, are firstly those roughcasts with different properties and grades after series technology processing from melting, milling, pressing to sintering in order. The (BH) max range is from 20 to 32, maximum working temperature 350¡ãC. Sm2Co17 bears a extremely low temperature coefficient and preferably anti-causticity. In high-temperature conditions, the magnetic properties is better than NdFeB magnets, As a result, it¡¯s widely used in fields¡£such as aeronautics and space, national defense and sensors. As a result of great brittleness of Sm2Co17 materials, it is not suitable for complex shapes and thin thickness disc or ring wall.Due to this character, there may be some appearance defects such as small chips during production, inspection and magnetizing process. However, it would not change its property; we consider them as qualified product. Magnetized SmCo products must be picked up carefully and gently during assemble process and kept away from ironware to avoid mutually attracting, causing chips and cracks. Sm2Co17 magnet is not easy to magnetize saturated, therefore, clients must be familiar with magnetization energy of their own magnetization equipments, to the effect that appropriate grade would be chose and products of company can be fully saturated. Please see magnetizing magnetic field of Application Technology for your reference. According to our customer.

Compared with ndfeb, it needn't to be coated. It can typically be used up to 300 'c. Therefore, it is used in those fields, that applications demand resistance to wide range temperature and environments. How ever, it is extremely brittle and the cost is relatively expensive. Sintered smco magnets usually divided into smco5 and sm2co17 according to the components.
