Are there any non fragile magnets?

Since I came into contact with magnet customers, I have often met customers asking if there are any non-breakable magnets? In other words, the magnets I buy now are fragile, do you have magnets that are not fragile? Some even posted videos of magnets breaking, saying they were very speechless. Today, Xiao Fu, the manufacturer of courage magnet, will give you a comprehensive science popularization about the fragile magnets, and introduce what magnet is not so fragile (broken)


First of all, I want to tell you that most of the magnets are fragile products, and there is no problem with the quality of the magnets. Most of what is said here is because there are still a small part of the magnet material that is not so fragile. I will also introduce it to everyone.


Including the black magnets that we played with when we were young, we only learned that the scientific name is ferrite magnets later. Some friends would say that magnets of this material are not so fragile, and there seems to be some truth. In fact, the fragility of a magnet is related to its shape and thickness. , The magnets that were removed from the speakers when they were young are usually relatively thick. In addition, the attraction force of ferrite magnets is not very strong. When the magnets are adsorbed on the surface of iron objects or the magnets collide with each other, the impact force is much smaller than that of strong magnets, so that it will not feel too fragile. When the wall thickness of ferrite is 1mm or thinner, it is also easy to break.

There is also the strongest sintered neodymium magnets with the strongest magnetic force. This kind of magnet is recognized as strong magnetic force and has many applications. It is also very fragile. When two strong magnets are attracted to each other, they will basically be rotten. The thickness of the magnet is thicker. The corners will drop, and the thinner magnet will split directly from the middle.


Samarium-cobalt magnets are the second most magnetic magnets today. They have a high maximum energy product (BHmax), high coercivity, fragile, and cracked. The maximum operating temperature can reach 350°C, and the negative temperature is not limited. When the operating temperature is above 180°C, its temperature stability and chemical stability exceed those of neodymium iron boron permanent magnet materials.


These are all sintering processes, and they are also the most common materials that are widely used. In addition, there are also several materials that are used in motors. I will also tell you today.


Bonded neodymium (Ndfeb) magnets, are also fragile, usually with a thin wall thickness of about 1mm, and they are basically scrapped when dropped on the ground.


There is another injection-molded magnets. Because the injection-molded magnet is an injection molding process, the composition contains nylon, so from the mechanical performance point of view, the injection-molded magnet is not so easy to break. Summary: The fragile permanent magnets include sintered ferrite magnets, sintered neodymium iron boron magnets, bonded neodymium iron boron magnets, and sintered samarium cobalt magnets. Injection magnets are relatively less fragile, and there are rubber magnets, which are not fragile after strong magnets are coated.


The above is an introduction to non-fragile magnets. If you want to learn more about magnets, please enter our Magnet Q&A column.
