How long can the suction force of NdFeB strong magnets be maintained?

As the name suggests, NdFeB strong magnets are mainly made of three materials: neodymium, iron, and boron. Of course, there are other elements. After all, the ingredients of different products are different, and the size of the magnetic force is determined by The ratio of these key materials is produced.

Therefore, if it is a professional magnet manufacturer, in the process of communicating with customers, it must provide products with suitable magnetic force (magnetism) according to the actual use requirements put forward by customers to ensure the normal use of products.

Similarly, the suction force of the NdFeB strong magnet is also restricted by many external conditions, such as the occasion of use, temperature, humidity and other factors, which will continuously lose the suction force of the strong magnet for a long time. Installation method is also a very important factor.

For example, strong magnets of the same size have different adsorption capacities for the same object to be attracted because of different grades. In addition, the magnets of the same size, we also use the same brand, but the suction force we actually tested is different for the front suction and the side suction of the same object. Furthermore, the size of the vertical suction for vertical installation and the size of horizontal suction for horizontal installation are different. is different.

Therefore, if you want to understand and buy a really suitable strong magnet product, you still need to go to a regular factory to buy it, so as to ensure the stability of the material and the correct reference for the size of the suction.

The industry has also discussed the maintenance of the magnetic properties of strong magnets for many years. Due to the variety of use environments and methods of strong magnet products, under normal circumstances, the suction force of strong magnets will not be affected by the outside world, so it is called It is a permanent magnet,

However, for the use of special envoys, such as salt spray resistance and corrosion resistance, the strong magnet itself will cause very large external damage, so the magnetic force will definitely be affected, and the magnetic performance will be lost over time.

Therefore, in special environments, it is necessary to choose raw materials suitable for special environments and suitable plating protection, so as to ensure the permanent suction of magnet products.
