Ferroboron

Features

As the only ferro boron manufacturer in Japan, Nippon Denko has an overwhelming market share for this item as a raw material for functional materials that support a wide range of energy-saving equipment, thus contributing to the enhancement of energy efficiency.

Uses

Amorphous alloys, used as steel cores for high-efficiency transformers with very little electrical loss, and neodymium iron boron magnets, used in motors for hybrid vehicles or electrical generators in wind power systems
