HIGH ENERGY FLEXIBLE MAGNETS
High Energy Flexible Magnets are composed of a strontium ferrite powder mixture with polymer bonding. These magnets are most commonly formed as strip. |
|
|
Attributes of High Energy Flexible Magnets
- High resistance to demagnetization compared to standard flexible magnet material
- Easy fabrication and handling
- Free from chipping, cracking or shattering
- Inexpensive
- High energy product vs. regular flexible material
- Adhesive or plain
- Low curie point, not good in heat applications
Applications
Motors, Sensors, Latches, Magnetic Assemblies, Electronics, Appliances, Holding, Actuators, Seals

Manufacturing High Energy Flexible Magnets
The raw material goes through a calendering process and then is formed into strip. It can then be easily machined to size and magnetized. High energy flexible magnets are anisotropic (oriented), whereas standard flexible magnetic material is not. Therefore, high energy magnets are limited to magnetization through the thickness, and are similar in strength to a Grade 1 ceramic magnet. Special magnetizing patterns available and may require fabrication of magnetizing fixtures.

Custom Orders and Manufacturing
High Energy Flexible Magnets are commonly manufactured in the forms of strips, sheets or die-cut pieces. High energy strip and sheets are available in a variety of energy levels. Some stock sizes with or without adhesive are available for immediate purchase, but we encourage you to contact us regarding your specific needs. Please provide the shape, size, thickness of material and tolerances needed. Also let us know whether or not your application requires an adhesive. Providing a drawing and description of the application is also helpful in quoting the correct magnet. Please let us know whether ferrous metal backing plates or other magnetic circuit enclosures will be used in your application. Fax your request and drawing toll-free to 1.800.874.6248, or e-mail to pmm@magnetsource.com.
Many shapes and sizes are available in stock now • Minimum quantities may apply to custom orders
