Everyone is familiar with magnets. The magnet in our first impression is that the surface is black. This re-magnet industry is called ferrite, but the widely used magnet is not the NdFeB magnet. Known as the "Magnetic King", a small powerful neodymium iron boron magnet is 30 to 50 times larger than a ferrite magnet!!! How is this strong magnet made?

Ningbo Permanent Magnet Material Co., Ltd.
The strong neodymium iron boron magnet is not itself a whole. It is made by mixing and sintering the main raw materials such as bismuth, iron and boron. After the mixing and sintering, the raw materials of our powerful magnets are made. There are two types of round and square.

Then, we went to the production stage of Permanent NdFeB magnets. According to the required size, the large blank material was cut by a slicer. After cutting, it was subjected to surface treatment or electroplating. Because it is like this kind of strong magnet, it is It is easy to be oxidized. It is easy to rust. Magnet plating is used to protect the magnet from corrosion and rust, but it has nothing to do with magnetic force. After electroplating, the magnet is actually not magnetic. At this time, the magnetizer is used to magnetize the magnet. After charging, it is the strong neodymium iron boron magnet we have seen.

The above is the simple process of producing strong NdFeB magnets. The Permanent is just a brief introduction. There are some small details that are not described here.
