Comparison of strong magnets and ordinary magnets

Many customers have such doubts in choosing magnets, that is, what kind of magnets should I choose, NdFeB powerful magnets or ferrite magnets? Where is the difference between strong magnets and ordinary magnets?

Advantages of NdFeB powerful magnets:

1. Strong magnets with strong magnetic force: NdFeB strong magnets are currently the strongest magnet material, which is many times stronger than ordinary magnets. Generally, workers who install these powerful magnets must be careful to avoid personal injury, which shows how strong their magnetic force is.

2. Powerful magnets are easy to process irregular shapes: the magnets can be perforated, slotted, and cut without opening a mold.

3. The hardness of the powerful magnet is hard: the density of rare elements is added to the powerful magnet, which is much harder than ordinary magnets.

4. High precision of strong magnets: the tolerance of strong magnets can be made to ±0.05 or even lower, but ferrite is generally difficult to achieve.

5. Powerful magnets are cost-effective: In all aspects, the value of powerful magnets is higher than that of ordinary magnets. Their strong magnetic force, stable resistance, suitable temperature resistance, and tolerance accuracy are all the advantages of powerful magnets. , so the price is slightly higher than ordinary magnets is also a matter of course. Whether it is low, medium and high end, this kind of powerful magnet is generally the main one.

How to choose between ordinary magnets and powerful magnets?

If the customer's requirements for the magnetic force of the magnet are not so strong, and the price requirement is lower, ferrite can be selected. On the contrary, if the magnetic force of the magnet is high, and the required magnet shape is more complicated, etc., it is enough to choose NdFeB.

The most obvious difference between ordinary magnets and powerful magnets: ordinary magnets are black magnets (without electroplating), and their magnetism is relatively weak; strong magnets are metal-colored magnets, and their magnetism is relatively strong. This trick can be used to distinguish when you don't know what magnet is in your hand.
