Although many people know magnets, they don't know that magnets are divided into many types, and "normal magnets" and "NdFeB magnets" are also very different. Magnets used in different industries are also very different.
Cylindrical magnet
1. According to the material to distinguish: magnets can be divided into NdFeB magnets, ferrite magnets, samarium cobalt magnets and AlNiCo magnets, and the popular ones are NdFeB magnets, which are super-magnetic Strong is called the "magnetic king" in the 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 are the differences between ordinary magnets and NdFeB magnets? 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 magnet are stronger than ordinary magnets. No matter which kind of strong magnet material is used, it is superior to ordinary magnets, so the limit temperature that the strong magnet itself can withstand is greatly improved. In the industrial industry, the machine can operate at high temperatures.

Second, the hardness is hard: because the NdFeB magnet increases the density of rare elements, it will be harder than ordinary magnets in hardness. Therefore, in the course of use, the cracking of the magnet due to the collision is largely avoided, and the ordinary magnet is fragile, and its appearance will rust for a long time.

Third, the magnetic strength: the ordinary magnet on the market is based on how many coins can be sucked to determine the size of its magnetic force, while the NdFeB strong magnet can absorb its own weight 640 times the weight, the magnetic can be imagined how much, Therefore, be careful to avoid being pinched when touching a strong magnet.

Fourth, the price: Although the magnetic strength of the NdFeB magnet is very strong, its price is directly proportional to itself, the so-called "one point for one price"
In summary, there is still a clear gap between NdFeB magnets and ordinary magnets. NdFeB magnets are generally used in industries such as industry and electronics.
