How long can the suction force of a strong magnet be maintained?

According to the conventional magnets, powerful magnets are also commonly known as permanent magnets, the professional name of rare earth NdFeB magnets, is a rare metal unique to China doped with some other metal materials synthesis sintered made, in the magnet types known as the magnetic king;

Features: the strongest magnetism, high performance, can be plated, (the most common only galvanized ZN, nickel plated NI; also some special requirements, such as gold plating, silver plating, colorful plating, etc., according to the demand we can plating), it is made of more than ten kinds of materials mixed, and the size of the magnetic force is generated by the ratio of these key materials. Therefore, if a professional magnet factory, in the process of communication with customers must be based on the actual use requirements of the guests to provide the appropriate magnetic size (suction size) of the product to ensure the normal use of the product.

The magnets are also subject to many external conditions, such as the use of the occasion, temperature, humidity and other factors will continue to lose the magnets' suction size. The installation method is also a very important factor.

For example: the same size of the strong magnet, because of the different grades, for the same piece of the object being sucked adsorption capacity is different. In addition or the same size magnet, we also use the same brand, but the front and side adsorption of the same object we actually tested the size of the suction force is not the same, and then again, the vertical installation of vertical adsorption and horizontal installation of horizontal adsorption size is different.

Therefore, if you want to understand and buy the right strong magnet products or need to go to the regular factory to buy, so as to ensure the stability of the material and the correct reference basis for the size of the suction.

The industry has been discussing the magnetic properties of powerful magnets for many years, and because of the wide variety of environments and ways of using powerful magnets, the suction force of powerful magnets is not affected by the outside world under regular circumstances, which is why they are called permanent magnets.

But for the special use of the situation, such as salt spray corrosion resistance, for the strong magnet itself will produce a very large external damage, so the magnetic force will certainly receive the impact of magnetic energy loss over time, so in the special environment, you need to choose the right raw materials for the special environment products and suitable plating protection, so as to ensure that the magnet product suction permanent.
