Tridus History

Tridus was incorporated in 1982 (Los Angeles, CA) and quickly established a joint venture with San Huan High-Tech., Inc to manufacture sintered NdFeB magnets in Ningbo China. In 1994, we acquired the exclusive North American distribution of Chinese manufactured NdFeB magnets in North America, our joint venture was the only Chinese licensee for 7 years. This position allowed Tridus to develop deeply embedded relationships with the Chinese magnet manufacturing community.

By 1988, our R&D Technology Center in Beijing was established and in 1996, we had achieved the first ISO 9001:2000 & TS 16949 certification in the China permanent magnet industry. Today, the Group holdings are publically traded.
