Samarium iron nitrogen system permanent magnet materials are a new type of rare earth permanent magnet materials following neodymium iron boron (the third generation of rare earth permanent magnet materials). This product primarily uses samarium oxide as the main rare earth raw material, and through equipment, it produces soft magnetic materials with high saturation magnetization. Its performance is comparable to that of flexible neodymium iron boron in terms of magnetic force, but the price is much cheaper than flexible neodymium iron boron. The product's appearance and feel are similar to ordinary rubber magnets.

Advantages of samarium iron nitrogen soft magnets: relatively high magnetic properties; flexibility similar to rubber magnets, allowing processing into any geometric shape; strong corrosion resistance, not easily oxidized.

Applications of samarium iron nitrogen soft magnets: motor magnetic strips, various magnetic attraction applications, can replace some neodymium iron boron strong magnetic products.
