Santoku's technology

Leading the world as a comprehensive manufacturer of rare earths

 Santoku launched into the field of rare earths in 1948. This was at the same time that the world’s advanced nations set out searching for the possibilities contained within new materials.
 It has been over half a century since then, and Santoku has grown to lead the world as a comprehensive rare earth manufacturer that carries out integrated production from raw materials to high purity compounds and assorted alloys.
 Not simply developing rare earths as basic materials, we are now pursuing their potential as high-functioning materials.

Accumulating original know-how for the manufacturing of rare earth metals and alloys

 Santoku was the first in the world to succeed in the molten salt electrolysis of rare earths as well as the mass production of rare earth rapid quenching alloys.
 By accumulating expertise on the manufacturing process ourselves, we were specifically able to refine our microstructure control technology for alloys. Responding to users’ needs for rare earth alloys and the peculiar properties they possess, we deliver products that have undergone a high level of microstructural control, which has led our customers to recognize the added value Santoku provides.
