About Our Patents
In 1991, our company was the first in the world to successfully mass produce thin pieces of unidirectional solidified RE-Fe-B based alloys for sintered magnets using a tundish Single Roll Strip Casting Process (hereafter referred to as “Santoku’s SC Process”). Currently, Santoku’s SC Process is the main technique used in Japan and around the world for the production of alloy raw materials used in high-performance magnets. Through our longstanding technology, we have continually provided major domestic and international magnet manufacturers with the alloy raw materials needed for their high-performance magnets.
Our company possesses both domestic and international patents for Santoku’s SC Process (hereafter referred to as “Santoku-held SC Process Patents”), and the majority of domestic manufacturers of alloy raw materials for high-performance magnets are licensees of Santoku-held SC Process Patents.
Among these, our patents for alloys, production methods and equipment are displayed on the chart below. For your reference, our company provides all patent information. For questions regarding these patents and licenses, please contact our department for intellectual properties.
