China Manufacturer Strong Smco Magnets For Sale
SmCo magnet is a high performance low temperature coefficient permanent magnet made of samarium and cobalt and other rare earth elements. Sm-Co magnets can be operated at higher temperature up to 300 C. Sm-Co materials come in energy products from 16 MGOe up to 33 MGOe. Their high resistance to demagnetizing influences and excellent thermal stability has ensured Sm-Co as the premium choice for the most demanding motor applications.

FAQ:
Q1. What is SmCo5?
A1. Samarium Cobalt (SmCo5 or Sm2Co17) and Neodymium-Iron-Boron (Nd2Fe14B) are both Rare Earth Magnets –the strongest known rare earth permanent magnets.
Q2. What is the composition of Sm2Co17?
A2. Sm2Co17 magnet is composed of Samarium-Cobalt alloys with SmCo ratio of 2 to 17, that is to say, 2 Samarium atoms with 17 Cobalt atoms. It also contains other elements such as iron, copper, Zirconium, Hafnium but in very small quantities. By weight the Samarium occupies about 25% of the total.
Q3. What are SmCo magnets used for?
A3. It is often used in aerospace, automotive and military applications. It is usually weaker than NdFeB Neodymium at room temperature. Samarium Cobalt SmCo is capable of use in extremes of cold and heat. It also has very high coercivity making it ideal for high temperature motor applications.
Q4. What is the temperature range for SmCo Block Magnets?
A4. SmCo Block Magnets can operate in temperatures up to 250-350°C (482-662°F), depending on the grade of the magnet.
Q5. How are SmCo Block Magnets stored and handled?
A5. SmCo Block Magnets should be stored away from other magnets and electronic devices, as they can interfere with their proper functioning. They should also be handled carefully to avoid cracking or chipping.
