Samarium Cobalt Magnets
High-Temperature Stability for Demanding Environments
Samarium cobalt magnets—often abbreviated SmCo magnets—are premium rare-earth magnets designed for applications where thermal stability, corrosion resistance, and long-term magnetic reliability are critical. While slightly weaker than neodymium magnets, samarium cobalt magnets excel in high-temperature, harsh, and mission-critical environments where neodymium may not be suitable.
As a trusted SmCo magnet supplier, we stock standard geometries, so you can move from concept to validation without delays. We support magnet selection for motors, sensors, medical devices, robotics, electronics, manufacturing, and R&D applications.

What Are Samarium Cobalt Magnets?
Samarium cobalt magnets are made from an alloy of samarium and cobalt, producing a rare-earth magnet with exceptional resistance to temperature-related demagnetization and corrosion.
SmCo magnets are often chosen when performance reliability outweighs cost considerations.
Key characteristics include:
Understanding SmCo Material Types
Grades are selected based on temperature limits, magnetic performance, and mechanical requirements, not strength alone.
Samarium cobalt magnets are commonly available in two material families:
SmCo 1:5 (SmCo5)
- Slightly lower strength
- Excellent stability
- Often used in precision instruments
SmCo 2:17 (Sm2Co17)
- Higher energy product
- Improved mechanical strength
- Widely used in motors and high-load applications
