NdFeB magnets are currently found the highest performance magnets, known as Magneto. Its chemical formula is Nd2Fe14B, the permanent magnet is an artificial, so far the strongest permanent magnets with having a magnetic force.

NdFeB magnets can be divided into two kinds of sintered NdFeB and Bonded NdFeB. Injection molding is actually bonded, and sintering is heated to high temperatures by vacuum molding!

NdFeB magnets as the third generation rare earth permanent magnet materials with high performance, which are widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, especially with the development of information technology as the representative of the knowledge-based economy, to rare earth permanent magnet NdFeB industry and other functional materials continue to bring new uses, which brings a broader market prospects for the NdFeB industry.

NdFeB magnets are tetragonal crystal made of neodymium, iron and boron formation. In 1982, Sumitomo Special Metals Sagawa discovered neodymium magnets. This magnetic energy product is greater than samarium cobalt magnets, and then became the world's largest energy product material. Later, Sumitomo Special Metals developed powder metallurgy successfully, GM's successful development Churning smelting method, capable of producing NdFeB magnets. This magnet is now the strongest magnetic permanent magnet, rare earth magnet is the most commonly used. It’s hard, stable performance, good price, so its application is extremely broad. But because of its chemical activity is very strong, it must deal with its surface coating. Everyday electronic products, such as hard disk, mobile phones, headsets, etc., there exists neodymium magnets.

As one of the rare earth material NdFeB material is the most important application areas, is one of modern electronic information industry to support important basic materials, and people's lives. With the rapid development and popularization of energy-efficient car computers, mobile phones, car phones and other communications equipment, the world demand for high-performance rare earth permanent magnet materials is growing rapidly. Neodymium magnet is essential as the permanent inverter compressor "heart". In the first decade of this century, China has completed the transformation from a permanent magnet material production country's largest producer of high-efficiency motors. Lots of equipment made from China with rare earth permanent magnet motor compressor began to export to European markets. China rare earth permanent magnet motordevelopment and huge industrial capacity, is leading the trend of frequency converter air compressor in the world.
