Hitachi Review

Highlight

As exploiting unutilized sources of heat energy, improving the efficiency of electrical power equipment, and energy efficiency are urgent issues for the creation of a sustainable society, Hitachi is developing innovative functional materials for achieving green innovation. Specifically, the materials under development include thermoelectric materials that take advantage of the ability of non-toxic and cheap silicon to convert waste heat into electric power, new magnetic materials that improve the electrical efficiency of electric motors using smaller quantities of rare earth metals, and a high-entropy alloy with high strength and corrosion resistance fabricated on 3D printers that provide energy-efficient processes for materials processing.
