Xg20 Smco Arc Magnet

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.

Samarium cobalt (smco) magnets, the second generation of rare earth magnet material, have high magnetic properties, excellent thermal stability and resistant to corrosion.

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.

Smco magnets have following applications:

Holding systems requiring very high holding forces,
High field yoke magnets,
High performance stepper,
Dc, servo, linear, and voice coil motors,
Magnetic bearings, magnetic couplings,
Loudspeakers, halbach arrays, headphones,
Microphones, magnetic separation, instrumentation, switches, relays, magnetic resonance, sputtering,
Vacuum deposition, charged particle beam guidance, particle accelerators, undulators, wigglers, and others.
