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%.
Features: no matter how bad the environment,its performance of magnetic is still strong!

CharacteristicSmco '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 Time15-30 DAYS(Depends on size and quantity)
Delivery PortNINGBO
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.

FAQ

Q1: Can I have a sample order for Neodymium magnet?
A: Yes, we welcome sample order to test and check quality. Low MOQ of 1pc for sample checking is available.Mixed samples are acceptable. Please cover the freight.

Q2: What about the lead time?
A:Sample needs 3-5 days, mass production time needs 15~30 days for each order in general.
 
Q3: How do you ship the goods and how long does it take to arrive?
A: We usually ship by DHL, UPS, FedEx or TNT. It would take around 3-5 days to arrive. Airline and sea shipping are also available.
 
Q4: Is it OK to print my logo on magnet product or package?
A: Yes. Please inform us formally before the production and confirm the design firstly based on our sample.
 
Q5: How are Neodymium Magnets made?
A: The main ingredients are Neodymium, Iron and Boron. The exact ingredients depend on the grade being produced. We also add a key ingredient called dysprosium to raise the coercivity of the material and increase the resistance to demagnetisation and corrosion. You can read more about the manufacturing process in our company website, www.hawellmagnetics.com.
 
Q6: How do you make our business long-term and good relationship?
A: We keep good quality and competitive price to ensure our customers' benefits. We respect every customer as our friend and we sincerely do business and make friends with them, no matter where they come from.
