China Supplier Customize Sintered SmCo Disc Magnets
Samarium Cobalt disc magnets feature a lot of magnetic strength and reliability in various temperatures. SmCo Cylindrical Magnet Comes in different forms Strong Magnetism force, comparable to Neodymium magnets (slightly less).Working temperature up to+200°C
SmCo magnets magnetic properties are not too far from Neodymium Iron Boron magnets but due to the cost and strategic value of Cobalt, it never had the commercial success and diffusion as NdFeB. Being a rare earth magnet it is an intermetallic compound of rare earth metals (samarium) and transition metals (cobalt). The production process consists of milling, pressing, and sintering in inert atmosphere: magnets are then pressed in an oil bath (isostatically) or in a die (axially or diametrically).

Features
Sintered SmCo Magnet offers strong resistance to demagnetization.
All Samarium Cobalt magnets cannot be formed with conventional drilling, turning or milling processes, and must be ground before they are magnetized.
Additionally, large or complex assemblies are usually magnetized prior to assembly. Standard tolerances for Samarium Cobalt magnets are +/-.005 for ground dimensions.
These magnets possess very high magnetic properties, excellent thermal stability, while remaining resistant to corrosion.
These characteristics make SmCo magnets ideal for applications requiring a resistance to wide-ranging temperatures and environments.
We offer many sizes and grades suitable for a variety of manufacturing, hobby and craft applications.
FAQ:
Q1. What are the grades of SmCo magnets?
A1. For Samarium Cobalt (SmCo) Magnets, the BHmax will range from 16 MGOe to 32 MGOe. Again, like neodymium magnets, the higher the number, the stronger the magnet. The common grades for Samarium Cobalt magnets are 16, 18, 20, 22, 24, 26, 28, 30, and 32.
Q2. What is Sm2Co17?
A2. Sm2Co17 (SmCo2:17) is the more common used and stronger SmCo alloy with SmCo26 being the most popular variety. Sm1Co5 contains mainly Sm and Co and contains no iron (Fe) so it has excellent corrosion resistance. Sm2Co17 is mainly Sm and Co but also contains Cu, Hf &/or Zr, sometimes Pr, and Fe.
Q3. Do samarium cobalt magnets rust?
A3. Typically samarium cobalt magnets do not require any coating or plating. That is because, unlike neodymium magnets, they contain little or no iron and therefore they have excellent resistance to corrosion.
Q4. Are Samarium Cobalt magnets stronger than neodymium?
A4. Although not as strong as a neodymium magnet – samarium cobalt magnets typically have an BHmax of about 26 – these magnets have the advantage of being able to withstand much higher temperatures than neodymium magnets.
Q5. What are the safety precautions for Rare Earth SmCo disc magnets?
A5. Care should be taken when handling Rare Earth SmCo disc magnets to avoid injuries from the strong magnetic field. They should also be kept away from electronic devices, pacemakers, or other medical devices that can be affected by their magnetic fields.
