SmCo magnet
Ideal for harsh environments where performance and reliability are crucial! Equipped with excellent thermal stability | SmCo magnets
The "SmCo Magnet" is a samarium-cobalt magnet suitable for harsh environments, characterized by its exceptional magnetic strength, thermal stability, and resistance to demagnetization. This product, manufactured through a sintering process, is very hard and brittle, requiring grinding for shaping. It has a high energy density and supports the miniaturization of magnetic components while maintaining strength. It exhibits excellent thermal stability, operating stably up to +250°C, and demonstrates outstanding demagnetization resistance, maintaining its properties even under strong reverse magnetic fields. 【Features】 ■ Rare Earth Composition: Composed of samarium and cobalt, exhibiting high magnetic properties ■ High Energy Density: Supports the miniaturization of magnetic components while maintaining strength ■ Excellent Thermal Stability: Operates stably up to +250°C, suitable for high-temperature applications ■ Outstanding Demagnetization Resistance: Maintains magnetic properties even under strong reverse magnetic fields ■ Precision Manufacturing: Due to the brittleness of the material, it is produced by sintering and finished by grinding *For more details, please download the PDF or feel free to contact us.
