Deskripsi Produk
High Temperature SmCo Rotor Magnet
Permanent Samarium Cobalt magnets (SmCo) are composed of samarium, cobalt and iron. These rare earth magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as Arc, rings, blocks and discs.
Attributes of Samarium Cobalt:
1. High resistance to demagnetization
2. High energy (magnetic strength is strong for its size)
3. Good temperature stability
Applications of Samarium Cobalt:
Computer disc drives, sensors, traveling wave tubes, linear actuators, satellite systems, motors where temporary stability is vital.

| Advantage | high performance, low termpeature coefficient with high working temperature-350 degree centigrade .When working over 180 degree centigrade, the maximum energy BH and steady temperature are superior than NdFeB magnet. it is not easy to corrode and oxidize as Neodymium magnets, so ineed not to be coated, demagnetization rate of <3%. | |||||||||
| Characteristic | Smco 's high magnetic force and working temperature : Compared to traditional motor, rare-earth magnet coreless motor with high efficiency, light weight, small size, good speed control, reliability, etc., can be widely used in wind power, electric vehicles, industrial motors, and other fields. In the low-carbon energy saving background, samarium cobalt market is very large. Currently in Japan and Europe and other countries use about 98% of the air-conditioning inverter air conditioner, but China seldom use. inverter air conditioner has a comfortable, energy-saving features, will become a trend in the future. | |||||||||
| Production Time | 15-30 DAYS(Depends on size and quantity) | |||||||||
| Delivery Port | NINGBO | |||||||||
| Application | Smco magnets can be used for coreless motor, variable frequency air conditioner, oil industry dewaxing device motor, sensors,computer disc driver, linear actuators etc, which have good application in the low-carbon , and enerty -saving | |||||||||

Samarium cobalt magnet is also called samarium cobalt permanent magnets, rare earth cobalt permanent magnets, etc. It is a magnetic material made of samarium, cobalt and other metal rare earth materials through proportioning, smelting into alloys, milling, pressing and sintering. With high magnetic energy product, extremely low temperature coefficient, the maximum working temperature can reach 350 ºC, and the negative temperature is not limited. When the working temperature is above 180 ºC, its maximum magnetic energy product and temperature stability and chemical stability are all better than NdFeB permanent magnet materials. It has strong corrosion resistance and oxidation resistance, so it is widely used in aerospace, defense and military industry, microwave devices, communications, medical equipment, instruments, meters, various magnetic transmission devices, sensors, magnetic processors, motors, magnetic cranes and other fields.
