Samarium magnets, also known as samarium cobalt magnets, are high-performance rare earth magnets designed for demanding applications where stability, durability, and resistance to extreme conditions are essential. While slightly less powerful than neodymium magnets, samarium magnets offer excellent magnetic strength combined with superior thermal and corrosion resistance.

At Jobmaster Magnets, our range of samarium magnets is engineered for professional and industrial use. These magnets are commonly used in aerospace, automotive systems, motors, sensors, medical equipment, and specialist industrial applications where consistent performance is required in high-temperature or harsh environments.

One of the key advantages of samarium magnets is their ability to maintain magnetic strength at elevated temperatures. They are also naturally resistant to corrosion, eliminating the need for protective coatings in many applications. This makes them a reliable choice for environments where moisture, chemicals, or temperature fluctuations are present.

Why choose samarium magnets?

Samarium magnets are chosen for applications that demand long-term stability and reliability. They offer excellent resistance to demagnetisation, strong performance at high operating temperatures, and dependable magnetic force over time. These properties make them ideal for precision applications where failure or performance loss is not an option.

Jobmaster Magnets supplies samarium magnets in a variety of shapes and sizes, with clear technical specifications to help you select the correct magnet for your requirements.

FREQUENTLY ASKED QUESTIONS

What are samarium cobalt magnets used for?

Samarium cobalt magnets are used in high-performance and specialist applications where stability and reliability are critical. Common uses include aerospace systems, automotive components, electric motors, sensors, medical equipment, and industrial machinery that operates in high-temperature or corrosive environments.

How do samarium cobalt magnets work?

Samarium cobalt magnets work by producing a strong and stable permanent magnetic field created from an alloy of samarium and cobalt. Once magnetised, they maintain consistent magnetic performance without the need for an external power source, even under extreme temperatures or demanding conditions.

How strong are samarium cobalt magnets?

Samarium cobalt magnets are very strong, offering high magnetic force compared to traditional ceramic magnets. While they are slightly less powerful than neodymium magnets, they provide excellent resistance to demagnetisation and superior performance at elevated temperatures.

Which is better neodymium or samarium magnets?

Neither is universally better, the best choice depends on the application. Neodymium magnets offer maximum magnetic strength in a compact size, making them ideal where space is limited. Samarium magnets are better suited for high-temperature or harsh environments due to their thermal stability and corrosion resistance.
