Although many people know about magnets, they don't know that magnets are divided into many types. "Normal magnets" and "NdFeB Neodymium magnets" are also very different. Magnets used in different industries are also very different.

1. According to the material to distinguish: magnets can be divided into NdFeB Neodymium magnets, ferrite magnets, samarium cobalt magnets and AlNiCo magnets, and popular NdFeB Neodymium magnets, which are super-magnetic, known as "magnetic king." magnet.

2. According to the magnetic distinction: can be divided into Permanent magnets and ordinary magnets.

3. According to the magnetic force to distinguish: can be divided into strong magnets and ordinary magnets.

So what is the difference between an ordinary magnet and a NdFeB neodymium magnet? Xiaobian will analyze and analyze for you in the following four ways.

First, the high temperature resistance: the indoor temperature and the Curie temperature of the NdFeB neodymium magnet are stronger than those of the ordinary magnet. No matter which kind of strong magnetic material is used, it is superior to ordinary magnets, so the extreme temperature that the strong magnet itself can withstand is greatly improved. In the industrial industry, machines can operate at high temperatures.

Second, the hardness is difficult: because the neodymium iron boron strong magnet increases the density of rare elements, the hardness will be harder than ordinary magnets. Therefore, in the course of use, the crack of the magnet due to the collision is largely avoided, and the ordinary magnet is fragile and the appearance is rusted for a long time.

Third, the magnetic field strength: the ordinary magnet on the market is based on how much money can be sucked to determine the size of its magnetic force, and NdFeB neodymium strong magnet can absorb 640 times its own weight, the magnetic force can be imagined, therefore, be careful to avoid contact with strong magnets It is squeezed.

Fourth, the price: Although the magnetic field strength of NdFeB neodymium magnets is very strong, but its price is directly proportional to itself, the so-called "one price point"

In summary, there is still a significant gap between NdFeB neodymium magnets and ordinary magnets. NdFeB neodymium magnets are commonly used in industries such as industry and electronics.

Which magnet should be chosen depends on the effect of the product and the effect to be achieved. Everbeen钕's professional magnet engineers can provide better advice!
