SmFeN Flexible Rubber Magnets

These SmFeN Flexible Rubber Magnets products are advanced rare-earth magnetic composites that merge the superior thermal stability of Samarium-Iron-Nitrogen (SmFeN) with the adaptability of rubber, engineered for extreme environments and precision applications. Key features and benefits include:

1. Exceptional High-Temperature Performance – Retains stable magnetic properties at temperatures up to 200°C+, outperforming NdFeB magnets in heat resistance, ideal for automotive, aerospace, or industrial systems exposed to thermal stress.
2. Intrinsic Corrosion Resistance – SmFeN’s inherent oxidation resistance eliminates the need for additional coatings, ensuring durability in humid, saline, or chemically aggressive environments.
3. High Magnetic Strength & Anisotropy – Delivers strong magnetic output with anisotropic alignment, enabling directional magnetic fields for sensors, actuators, or energy-efficient motor designs.
4. Flexible & Lightweight – Magnetic particles embedded in rubber/polymer matrices allow bending, shaping, and adhesion to curved surfaces (e.g., rotors, housings) without cracking or performance loss.
5. Sustainable & Cost-Efficient – Reduced reliance on heavy rare-earth elements and elimination of coatings lower lifecycle costs, aligning with eco-friendly manufacturing goals.

Typical applications:

1. Automotive high-temperature components: turbocharger magnetic sensors, motor cooling system seals;
2. Aerospace: high temperature hatch magnetic seals, magnetic fixation of navigation equipment;
3. Industrial automation: material positioning in high temperature furnaces, magnetic drive systems;
4. Renewable energy: magnetic brake pads for wind turbines, drive modules for solar trackers;
5. High-end medical equipment: magnetic fixation of instruments in high-temperature sterilization environment.
