Santoku entered the rare earth field in 1948 — a time when advanced nations around the world were simultaneously beginning to explore the possibilities of new materials.
More than half a century later, Santoku has grown to become a world-leading comprehensive rare earth manufacturer, with integrated production spanning from raw materials to high-purity compounds and various alloys.
Today, we are not only pursuing the development of rare earths as raw materials, but we are also placing great hope in exploring their potential as high-performance materials.

Accumulating unique know-how in the manufacturing processes of rare earth metals and alloys

Santoku was the first company in the world to successfully commercialize rare earth molten salt electrolysis and mass production of rare earth rapidly solidified alloys. By continuously building on proprietary manufacturing process know-how, we have particularly honed our microstructure control technology for alloys. By incorporating user feedback for rare earth alloys with unique characteristics and providing products with high-level microstructure control, we deliver added value that is recognized and appreciated by our customers.
