———————————————    SAMARIUM COBALT MAGNETS    ———————————————

Samaryum Cobalt magnets are sintered magnets composed of samaryum and cobalt powder. Colour hell grey. Density 8.2

HOLDING FORCE ▶Magnetic force is optimal when magnet is in contact with a mild steel frame, flat, clean and rather thick. It is lower with allied steels and cast iron (less 30% for cast iron). ▶ It is lower in the presence of an air gap (space between the part to magnetize and the polar face of the magnet). ▶ It is decreasing by 0.08% every degree C (see besides curve). This loss is reversible. INDUCTION ON SURFACE ▶ The maximum value of induction in surface at 20°C is about 4000 Gauss for SmCo flat pot magnets and magnetic blocks. ▶ This value is decreasing by 0.04% every degree C when temperature is increasing. It is a reversible loss. MECHANICAL RESISTANCE ▶ These ceramics are very fragile. They must be handled carefully. RESISTANCE TO CHEMICALS        ▶ Samaryum Cobalt magnets must not be put in the proximity of hydrogen and chlorine. ➔Would you like to know more about the composition, main characteristics, and applications of Samarium Cobalt magnets ?

▶Samaryum Cobalt magnets have a very high magnetic energy (BH Max). ▶ There are 2 major families : SmCo5 and Sm2Co17. ▶ The usual grade of our magnets is the most performing Sm2Co17 (max. 350°C working temperature).   Nuances Sm2Co17 Br Typique (T) 1.06 Hcb Typique (kA/m) 720 Hcj Typique (kA/m) 1650 BH max Typique (kl/m³) 195 350°C maximum
