Beijing Jingci Magnetism Technology Co. (BJMT) is one of the largest manufacturers of sintered NdFeB magnets in China. BJMT was founded in 1987 and since its establishment, there were high growing rates every year. Now, BJMT is a company with 4 factories and 400 employees, with a production capacity of 1000 metric tons of sintered NdFeB magnets per year.

The magnets of BJMT are mainly applied in MRI, automotive, Motor, computer peripherals, cellular phone and HiFi audio system including various kinds of loudspeakers.

BJMT supplies its products to customers across Asia, Europe and North America with the support of its own local distributors in Germany and the United States. BJMT offers its customers high quality rare earth magnets in a wide range of different shapes, sizes and grades. The whole production from the raw material mining till the packing and shipping of the finished magnets is done by BJMT itself. BJMT obtained ISO9002:1994 in 1998 and ISO9001:2000 in 2002. Now BJMT follows its Quality Management System strictly in her daily operation.

In March 6, 2000, BJMT and Sumitomo Special Metals Corp.(SSMC) signed a patent license agreement, by which BJMT's products can be sold in North America and Europe. Now, BJMT is in a good position to expand its business in both United States and European Community. The long-term target of BJMT is to be one of the Top Ten on the international market.

Sumitomo Special Metals Co., Ltd. (Sumitomo) and Beijing Jingci Magnetism Tech. Co., (BJMT) concluded a Patent License Agreement dated March 6, 2000 regarding the manufacture and sales of Nd-Fe-B type anisotropic sintered magnets.

1.Cross-License Agreement between Sumitomo and Magnequench
