High-Performance Magnets with Excellent Temperature Stability
Samarium cobalt magnets (also known as SmCo magnets), are extremely powerful permanent magnets. Part of the rare-earth magnet family, SmCo magnets rank similarly in strength to neodymium magnets but have much higher temperature stability and higher coercivity. They can operate at temperatures up to 525°F (300°C). In addition, they have a very high resistance to demagnetization and to corrosion. SmCo magnets are available in numerous shapes, sizes and grades that span a wide range of properties and application requirements.

Samarium Cobalt Magnet Applications
Samarium cobalt magnets are often used in applications involving elevated temperatures where magnetic strength and stability are critical, space is a limiting factor and where the magnets may be exposed to radiation. They are routinely used in high-performance motors, machinery, pumps, medical devices, magnetic couplings, magnetic separators and other equipment for automotive, aerospace, medical, military and industrial automation industries. We are trusted partners to businesses worldwide in these primary markets.

Samarium Cobalt Magnets Features & Characteristics
- Grades & Materials - We carry a large inventory of licensed, samarium cobalt magnet materials in standard and premium grades for reduced production and lead times. We offer sintered SmCo magnets in grades that range from 16 MGOe to 33 MGOe. Visit our SmCo magnet materials page for additional information and for data sheets about this material.
- Sizes & Shapes - Standard samarium cobalt magnet shapes include discs, blocks, rings, and arc segments in a variety of sizes and grades. Non-standard shapes can also be custom fabricated to blueprint specifications from raw stock. We can custom manufacture samarium cobalt magnets in virtually any shape and size to meet your project’s exact requirements.
- Temperature Considerations - Samarium cobalt magnets exhibit magnetic properties that are very stable with temperature, and can be used in applications where temperatures reach up to 572°F (300°C). They perform well for applications where the stability of magnetic characteristics is critical.
- Manufacturing Methods - Samarium cobalt magnets are extremely brittle, so they are prone to chipping and cracking. Therefore, special machining techniques involving diamond-grinding must be used to machine this material prior to magnetization. We are fully equipped to machine these materials to your project’s specialty requirements.
- Surface Treatments - The corrosion resistance of Samarium Cobalt is very good, therefore coatings to prevent corrosion or oxidation are generally not required.
- Magnetizing & Assembly Considerations - SmCo magnets are anisotropic, and can only be magnetized in the orientation direction. Magnetizing fields in excess of 50 kOe are required to saturate these materials.
- Handling & Storage - Samarium cobalt magnets are extremely brittle, but magnetically very strong. Therefore, special care must be taken when handling these to avoid injury to personnel and damage to the magnets.
