HCSFY240L Melt Flow Rate 260 SmFeN Magnets

SmFeN magnets, also known as Sm 2 Fe 17 N 3, have been anticipated as a potential choice for the next generation of permanent magnet materials, SmFeN has many advantages, including:

• Curie temperatures up to 476 degrees Celsius, much higher than conventional sintered Nd magnets.
• The magnet crystal anisotropy field is three times that of Nd 2 Fe 14 B, offering great potential for high coercivity magnets.
• SmFeN magnets can be magnetically tuned without the addition of cobalt or other heavy rare earth elements (HREE).
• Excellent corrosion and oxidation resistance.

The Sm 2 Fe 17 N 3 phase decomposes into SmN and α-Fe phases once the ambient temperature exceeds 650 degrees Celsius. SmFeN magnets were first commercialized by Japanese companies in the field of bonded magnets. The isotropic magnets or anisotropic magnets require a stable raw material SmFeN powder. Both Nichia and Sumitomo used reduction diffusion to obtain anisotropic powders that are well suited for injection molding magnets.
