Product Overview
These disc SmCo magnets are made for industrial uses where reliable magnetic performance and great thermal stability are essential. They maintain their magnetic strength even when exposed to high temperatures and frequent heat cycles since they are made of sintered samarium cobalt (Sm2Co17). They are simple to include into rotors, sensors, and precision assemblies due to their disc geometry.
SmCo is a recommended option for engineers that prioritize dependability over maximal flux density since it exhibits predictable behavior in demanding settings as compared to ordinary ferrite or NdFeB magnets.

Material Characteristics
- Material: Sintered Sm2Co17 (samarium cobalt)
- Temperature Resistance: Effective up to ~250 °C
- Magnetization: Axial or radial, customizable to application needs
- Surface Finish: As-sintered or epoxy-coated for additional protection
- Mechanical Properties: Hard and brittle; careful handling required
These properties ensure long-term stability and minimize performance loss in motors, actuators, and precision instruments.
Practical Applications
Disc SmCo magnets are widely used in systems where reliability under thermal stress is critical:
- Industrial and brushless motor rotors
- Aerospace actuators and navigation components
- Sensors, rotary encoders, and precision instruments
- Robotics modules and high-temperature automation equipment
The magnets provide uniform flux, supporting consistent torque and motion control, while their compact disc form allows easy assembly in confined spaces.
