OREANDA-NEWS. Nippon Steel and Sumitomo Metal Corporation (NSSMC) has developed a method of manufacturing special rolled titanium foil, which has excellent corrosion resistance against the corrosive environment in key parts inside fuel cells. As a result, this material has been adopted in parts for the fuel cell (the parts that make up the cells inside the fuel-cell stack) of the "Mirai" fuel-cell vehicle produced by Toyota Motor Corporation.

Titanium is a material that has various functions, namely, outstanding lightness, strength, and corrosion resistance. Thanks to these properties, it is used in a wide range of fields extending from aircraft, electric power and chemical plants, and automobile components to consumer products such as eye glasses and watches, thereby supporting societies in a broad range of ways. Since introducing a precision rolling mill at the Naoetsu Works in 1987, NSSMC has been providing high-quality, high-value-added titanium foil products.

Based on the adoption of this product in the "Mirai" on this occasion, NSSMC will continue to cultivate new areas of demand and expand applications for titanium products. This includes accelerating the advance into highly innovative business sectors that will play a role in the hydrogen society expected in the future.
