GB/T13560-2000 Summary Of Standards For Sintered NdFeB Permanent Magnetic Materials

- Nov 08, 2017 -


With the growth of China's rare earth permanent magnet production and trade, GB / T13560-2000 "Sintered NdFeB Permanent Magnet Material" national standard will play a significant role in regulating the market, unifying the testing methods, improving and controlling product quality. The original GB / T13560-1992 "sintered NdFeB permanent magnet materials," the national standard was formulated in 1992. In recent years, due to the popularization of communication devices such as computers, pagers, mobile phones and car telephones, and the rapid development of energy-saving vehicles, the neodymium rare earth magnet materials have superior magnetic properties and richer raw material resources than other permanent magnet materials , Lower prices and other advantages of the global demand for high-performance neodymium magnet material rapid growth of rare earth permanent magnet material output increased by about 30% each year.

According to the information reported in 2000, China's sintered NdFeB total of more than 150 manufacturers, the output has reached 6,000 tons. Product performance and appearance of the quality has also been greatly improved, forming a variety of uses for a variety of magnetic properties of products. In order to meet the needs of market development of sintered NdFeB permanent magnet materials both at home and abroad, Baotou Rare Earth Research Institute is responsible for the revision of the standard. 

During the revision of GB / T13560-1992 standard, we extensively collected the opinions of domestic and foreign standards, manufacturers and users, made major revisions and supplements to the original standards, increased the medium and high-grade magnetic energy product and high coercion Powerful products. The revised standards, more in line with the current production and use of more scientific, advanced and operational. In order to make the relevant parties better understand the standard conditions at home and abroad, and facilitate the production and trade exchanges between enterprises, this paper presents a comprehensive review of the new standards in light of the current industry status of sintered NdFeB materials.
