SM2CO17 & SMCO5 CHEMICAL COMPOSITION

sm2co17 chemical composition

The 2:17 type sintered samarium cobalt permanent magnet material is based on the intermetallic compound Sm2Co17. By adding copper (Cu), iron (Fe), zirconium (Zr), etc., high-performance permanent magnet materials can be obtained; using gadolinium (Gd), Erbium (Er) and other heavy rare earth metals can replace part of samarium (Sm) to obtain low remanence temperature coefficient permanent magnet materials.

The chemical composition range of the materials is shown in the table below.

ComponentSmFeCuZrCo
Content (%)24~286~254~120~4the Remaining
