Smco Magnet

Samarium Cobalt (SmCo) Composition: Samarium (Sm) and cobalt (Co), categorized into SmCo₅ (1:5 type) and Sm₂Co₁₇ (2:17 type). Cost-effectiveness: Expensive (due to scarce cobalt resources) but excels in extreme environments with high-temperature and corrosion resistance. Application Fields: Aerospace, military equipment (e.g., missile guidance), high-temperature motors, petroleum exploration instruments, precision sensors. Magnetic Properties: Moderate magnetic energy product (18–32 MGOe), extremely high coercivity, outstanding temperature stability. Curie temperature up to 800–1000°C; capable of long-term operation at 302°C. Operating Environment: Naturally corrosion-resistant (typically no coating required). Radiation-resistant; suitable for space and nuclear industries.
