What Are Samarium Cobalt Magnets?

earth3Rochester Magnet offers Samarium Cobalt magnets in blocks, discs, and rings. Samarium Cobalt is an alternative to Neodymium-lron-Boron (NdFeB), as SmCo magnets can withstand much higher temperatures and are more corrosion resistant than NdFeB. Samarium Cobalt is more costly than NdFeB due to the market price sensitivity of Cobalt. These magnets are brittle and can be prone to chipping or cracking. SmCo is used in computer disk drives, sensors, traveling wave tubes, linear actuators, satellite systems and some motors.

Sintered Samarium Cobalt rare earth magnets are extremely resistant to demagnetization and they can operate at temperatures up to 500F (260C). There are many Samarium Cobalt grades which can withstand higher temperatures, but several factors will dictate the overall performance of the Samarium Cobalt rare earth magnet. One of the most pertinent variables is the geometry of the magnet or magnetic circuit. Samarium Cobalt magnets which are relatively thin compared to their pole cross-section (Magnetic Length / Pole Area) will demagnetize easier than Samarium Cobalt magnets which are thick. Magnetic geometries utilizing backing plates, yokes, or return path structures will respond better to increased temperatures.

When you work with us, we'll help you get the highest performance products for your operations. Our SmCo magnet prices offer an investment with long-term value because of our products' high durability and reliability for demanding operating requirements. With our products, you'll get exceptional quality in your magnets to ensure optimal functioning and endurance even with heavy use.

Applications for SmCo Magnets

Many different industries use samarium cobalt magnets, including military, aerospace and manufacturing fields, for a wide range of operations. Some of the typical applications of these magnets are:

  • Generators: For generators operating under high temperatures, SmCo magnets offer the functionality to keep the operation going smoothly.
  • Pump couplings: As pump couplings transmit power to the pump motor, they can get reliable performance for their critical operational role from SmCo magnets.
  • Sensors: The right magnet working with sensors can optimize their performance even with heavy use and high-temperature environments.
  • Motors: For reliable, seamless operation, these magnets can be a critical component of motor function.
  • Marine applications: Various marine applications working in potentially extreme environments can rely on rugged SmCo magnet products to maintain operation.
