Talk about the application and main components of NdFeB magnets
Jun 08, 2018

Magnets have a very wide range of applications in daily life. With the continuous development and progress, people have discovered NdFeB magnets with better magnetic properties and better performance. Its chemical formula is Nd2Fe14B, an artificial permanent magnet with superior super magnetic force.

 

For a long time, it was known as the "Magnetic King." In comparison, NdFeB magnets have ultra-high magnetic properties. Its maximum magnetic energy product is more than 10 times that of ferrite. Its own machining performance is also quite good. Working temperature up to 200 degrees Celsius. And its hard texture, stable performance, a very good price, so its application is extremely wide. However, due to its strong chemical activity, it is necessary to coat the surface, for example, Zn, Ni, electrophoresis, and passivation.

 

From the chemical formula, the neodymium-iron-boron magnet is mainly composed of chemical elements such as niobium, iron and boron. Due to outstanding performance, it has occupied an increasingly important position in many fields. For example, it can be applied to different fields. And for different user requirements, can produce different shapes of products, such as disc-shaped, circular, rectangular, curved and other shapes and so on.

 

As far as the current application is concerned, NdFeB magnets have long been widely used in electronic products such as hard disks, mobile phones, headphones, etc. due to their excellent magnetic characteristics. We know that there is a magnetic field around and inside the product, usually made of a metal alloy, with strong magnetic properties.

 

In the field of magnets, there is a large category of natural magnets. The main component of this type of product is triiron tetroxide, which is often called "magnetic iron oxide." With magnetic black crystals. It can be seen as a compound composed of ferrous oxide and iron oxide. Because there are two kinds of ions of different valences in the crystal of triiron tetroxide, it belongs to a more complex compound, which is mainly used for making primers and topcoats. It is also used in magnetic materials for the electronics industry. It is also used in Rust inhibitors for the construction industry.
