About Tridus

Welcome to Tridus! Since 1982, Tridus has dedicated itself to the development, manufacture and marketing of rare earth permanent magnets. During the past 35 years, Tridus has been leading the development of the North American rare earth permanent magnet industry. Our magnets are used in a myriad of applications ranging from branded high end audio transducers to current model year electric vehicles. Tridus is committed to serving its customers with high quality products and services.


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 1993 our joint venture signed patent license agreements, authorizing us the manufacture and sell sintered NdFeB magnets. Our joint venture was the exclusive Chinese licensee for more than 7 years. Today, we are a leading supplier of rare earth permanent magnets and our group holdings are publically traded on the Shenzhen stock exchange.
