1. Magnetic materials: There are many classification methods for magnetic materials, which can be divided into industrial grade and civilian grade according to their use; According to performance, it can be divided into soft magnetic materials and hard magnetic materials; According to different application ranges, it can be divided into permanent magnetic field materials and Gaussian distributed electromagnets (such as motor rotors).
Sintered NdFeB magnets are a type of permanent magnet made from an alloy of neodymium, iron, and boron. They are known for their exceptional magnetic properties, including high magnetic strength, high coercivity, and high energy density. The manufacturing process of sintered NdFeB magnets involves the powder metallurg
A Brief History of Magnetic Materials
China is the first country in the world to discover and apply magnetic materials. As early as the Warring States Period, there were records on natural magnetic materials (such as magnetite). The method of manufacturing artificial permanent magnetic materials was invented in the 11th century. In 1086, Mengxi Bitan recorded the production and use of the compass. From 1099 to 1102, a compass was used to record navigation, and the phenomenon of geomagnetic declination was also found.
The prices of neodymium rose by 30,000 yuan/mt to 890,000-900,000 yuan/mt on October 28.
