Advantages
  • High Magnetic Strength: Superior holding power for various applications.
  • Thermal Stability: Can operate at temperatures between 250°C and 550°C, with Curie temperatures ranging from 700°C to 800°C.
  • Corrosion Resistance: Less prone to oxidation and typically do not require additional coatings.
  • Demagnetization Resistance: High resistance to losing magnetic properties.
  • Hard and Brittle: Prone to chipping and cracking if dropped .
  • Temperature Tolerance: Suitable for high-temperature applications.
  • Machining and Magnetization: Require special handling and magnetizing fixtures; cannot be formed using conventional drilling or milling processes.

Samarium Cobalt magnets are used in various high-performance applications, including:

  • High-performance motors
  • Magnetic couplings
  • Magnetic separators
  • Electric devices
  • Industrial lifting

1:5 offers 16 MGOe (energy product) to 22 MGOe and is made up of approximately 37% samarium and 63% cobalt. The 1:5 series has a maximum recommended operating temperature of 250°C. SmCo 1:5 magnets require lower field strengths than 2:17 materials to magnetize. In some instances, 1:5  material may be magnetized with multiple poles, provided that a magnetizing fixture is available.

2:17 offers 24 MGOe to 32 MGOe and is composed of about 25% samarium, 5% copper, 18% iron, 2% hafnium or zirconium, with the remainder being cobalt. The 2:17 series has a maximum operating temperature of 350°C. Special grades of 2:17 are available which can operate to even higher temperatures. SmCo 2:17 requires a higher magnetizing field than alloy 1:5 does, and multiple pole magnetization is sometimes possible, provided that a magnetizing fixture is available.
