This guide is for engineers, hobbyists, and professionals working in demanding environments. The FIRST4MAGNETS Samarium Cobalt magnets offer exceptional performance at high temperatures and superior corrosion resistance, making them ideal for harsh conditions where other magnets fail. A key consideration is their slightly lower pull force compared to neodymium magnets. This product features samarium cobalt rare earth magnets, designed for high-temperature applications, boasting excellent corrosion resistance without coatings and a pull force of up to 3.3kg.

They are ideal for high-temperature applications like electric motors, turbo machinery, sensors, and any scenario requiring strong magnetic force in harsh or corrosive environments due to their thermal stability and corrosion resistance.
A 3.3kg pull force indicates the approximate weight the magnet can hold when in direct contact with a thick mild steel plate under ideal conditions. This is a significant force for a magnet of this size.
No, samarium cobalt magnets offer excellent inherent corrosion resistance and typically do not require an additional protective coating, making them suitable for direct outdoor or marine use.
Neodymium magnets generally offer a higher pull force for their size at room temperature. However, samarium cobalt magnets are superior in high-temperature environments and offer better corrosion resistance.
Samarium cobalt magnets are known for their high-temperature performance, typically operating effectively at temperatures up to 350°C (662°F), though specific grades may vary.
Handle with care. They can be brittle and may chip or shatter if dropped or subjected to strong impact. Keep them away from pacemakers and sensitive electronic devices.
This indicates the precision of the magnet's dimensions. The actual measurements will be within 0.1mm of the stated 25mm x 10mm x 3mm size, ensuring consistent fit in applications.
Ensure the magnet is directly contacting a suitable ferrous material. Check for any non-ferrous barriers or extreme temperatures that might affect performance. Verify the orientation of poles if used in proximity to other magnets.
Handle magnets with extreme care, avoiding dropping or forceful impact. If minor chipping occurs, the magnetic function may be reduced but often remains usable for less critical applications. If severely damaged, replacement is recommended.
While samarium cobalt offers superior corrosion resistance, prolonged extreme exposure can still cause degradation. Ensure the magnet is cleaned and dried after exposure to harsh chemicals or environments. If corrosion is severe, consider replacing the magnet.
These magnets are designed for direct integration into various applications. Ensure the mounting surface is clean and free of debris. The magnetic pull force of up to 3.3kg should be considered when designing attachment mechanisms. Compatibility is high with ferrous materials for attraction. For care, avoid exposing the magnets to temperatures exceeding their operational limits (though they are designed for high temperatures, specific limits should be consulted if available). Due to their rare earth composition, they can be brittle; handle with care to prevent chipping or shattering. Store magnets away from sensitive electronic equipment or magnetic media. Cleaning can be done with a dry or slightly damp cloth; avoid abrasive cleaners or solvents.
