Flexible magnets are made from ferrite or rare-earth magnetic powders mixed with rubber or plastic binders and formed into sheets, strips, or rolls. They can be easily cut, bent, and shaped while maintaining stable magnetism. With good flexibility, corrosion resistance, and cost efficiency, flexible magnets are widely used in advertising displays, seals, labels, sensors, and light-duty industrial applications.

*Note: The maximum operating temperature and other performance characteristics of a magnet are dependent on the specific material type, magnetic circuit, and application conditions. The values provided above are guidelines for each material type under standard conditions. For example, the Curie temperature (the temperature at which a magnet loses its magnetism and cannot be remagnetized) varies significantly among different materials: Alnico magnets typically have higher Curie temperatures (e.g., 860°C for some grades), while standard neodymium magnets have a Curie temperature around 310°C (590°F). Always refer to the specific material grade and application requirements for accurate performance limits. If you need further assistance with selecting the right material or understanding the temperature limits for your specific application, please contact our technical support. Data Sheet
