Ningbo Zhuangli Magnetics Import & Export Co., Ltd. with 50, 000 m2 factory are engaged in manufacturing Sintered NdFeB with annual 2, 000tons and finely make Sm-Co, Al-Ni-Co and various kinds of magnetic assemblies. We also supply patented magnets. 
Our Sintered Neodymium: N52/N48M/N44H/N42SH/N38UH/N35EH with the highest working temperature 200 centigrade degree. 
Our most advanced technology: We can make two different series of sintered NdFeB magnets--- ordinary book mold alloy and magnets (HAST NdFeB) based on a strip cast alloy which gives a better chemical stability. We has invested in the production technology enabling to use strip cast material. 
HAST NdFeB magnets have higher anticorrosion and can last for 10 days under 120 degree Celsius, 95% humidity and 2atmp with loss of weight less than 10mg/cm2. 
Quality System: This corporation has already passed ISO 9001: 2000 international certification by SGS and European CE certification and TS16949 is operating on trial basis. 
In addition to standard shapes we can also supply magnet systems according to individual customer specifications. Meanwhile, we supply Ferrite magnets, rubber magnets.
