Samarium iron nitride magnet refers to ternary or multicomponent intermetallic compounds such as R2Fe17Nx or R2Fe17NxH formed by nitriding treatment of R2Fe17. Samarium iron nitrogen type permanent magnet materials are the third generation permanent magnet materials. Although neodymium iron boron permanent magnet materials have excellent magnetic properties, their Curie temperature is low. In some special applications, neodymium iron boron cannot meet the requirements. Based on the second-generation samarium cobalt type permanent magnet materials, improvements have been made to ensure that the permanent magnet materials can adapt to certain high-temperature environments and further enhance their magnetic properties.
SmFeN magnetic powder is suitable for preparing various forms of new high-performance rare earth bonded magnets through injection molding, extrusion, rolling, 3D printing and other process methods. Its outstanding features include high magnetic properties, uniform magnetic properties, high mechanical strength, flexible molding process, low eddy current loss, and high energy conversion efficiency. The average particle size of magnetic powder is small, and it has strong resistance to oxidation and corrosion. Our company can provide magnetic powders with specific physical characteristics (such as particle size) and different magnetic performance indicators (such as maximum magnetic energy product, remanence, intrinsic coercivity, etc.) according to customer needs.
SmFeN magnets are made from a combination of samarium (Sm), iron (Fe), and nitrogen (N) elements. Here are some key features and characteristics of SmFeN magnets:
Composition: SmFeN are primarily composed of samarium (Sm) and iron (Fe) with the addition of nitrogen (N). The exact composition can vary, but it typically consists of Sm2Fe17N3 or similar chemical formulas.
Magnetic Strength: SmFeN are known for their high magnetic strength. They can produce magnetic fields that are comparable to or even stronger than neodymium magnets, which are among the strongest permanent magnets available.
Temperature Stability: These magnets exhibit excellent temperature stability, meaning their magnetic properties remain relatively consistent over a wide range of temperatures. This makes them suitable for applications in environments with varying temperature conditions.
Corrosion Resistance: SmFeN are relatively corrosion-resistant compared to some other types of magnets, such as samarium-cobalt magnets. However, they may still require protective coatings in certain applications to prevent corrosion.
Applications: SmFeN magnets find use in various industrial and technological applications, including:
Electric motors and generators
Magnetic sensors
Magnetic bearings
Magnetic resonance imaging (MRI) systems
Magnetic separators
Aerospace and defense applications
Customization: SmFeN magnets can be tailored to specific application requirements by adjusting their composition, size, and shape. This flexibility allows them to be used in a wide range of devices and systems.
