Typical Demagnetization Cure


Information needed for magnet inquiry

It will be better if customer could send us detailed drawing including below information.

1. Magnet drawing

2. Magnet material

2. Magnet dimension: width, thickness, tolerance.

3. Magnet grade

4. Magnet applications

5. Required quantity: normally its weight or quantity

6. Other technical requirement.

If you are not sure which grade is proper, please contact our engineer. We can also customize according to your needs

We can offer a variety of NdFeB Magnet and Ferrite Magnet, If you need special magnetic tiles, we can also customize according to your needs.
