NIPPON KINZOKU Accelerates Global Sales of Ultra-Thin Electrical Steel Strips "GT Series" and "ST Series" as "Fine Eco Metal" Environmentally Friendly Products

About this update from Nippon Kinzoku Co., Ltd.

- Delivering the ultimate balance of "Ultra-Thinness" and "Low Core Loss" to drastically reduce high-frequency energy loss - TOKYO, July 09, 2026--(BUSINESS WIRE)--NIPPON KINZOKU CO., LTD. (Headquarters: Minato-ku, Tokyo; President: Yasushi Shimokawa; TOKYO: 5491) and its subsidiary, NIKKIN DENJI KOGYO CO., LTD. (Headquarters: Kawaguchi, Saitama; President: Akira Nishimura), are launching a strategic sales initiative for their ultra-thin Grain-Oriented (GT Series) and Non-Oriented (ST Series) electrical steel strips under the brand name "Fine Eco Metal". "Fine Eco Metal" is a brand name for our proprietary "Eco-Product" series, certified based on our own environmental standards. Background and Objectives: Addressing the "Shift to Electrification" Amid the global movement toward a decarbonized society, there is an increasing demand for the electrification and higher efficiency of equipment. This has intensified the need to minimize energy loss (core loss), particularly in high-frequency ranges. Leveraging years of proprietary rolling and advanced heat treatment technologies, we have successfully achieved both "unmatched thinness" and "superior magnetic properties" - a combination typically difficult to reach with conventional electrical steel. By positioning these products as "Fine Eco Metal," we aim to accelerate our solutions for customers developing next-generation technologies. Product Lineup 1) Ultra-Thin Grain-Oriented Electrical Steel Strips: "GT Series" By aligning the crystal grain orientation in a specific direction, this series delivers exceptionally high magnetic properties in that direction. Being significantly thinner (0.04mm to 0.10mm) than conventional grain-oriented strips, it dramatically reduces eddy current loss in high-frequency environments. Applications: High-frequency transformers, reactors, pulse power supplies, magnetic shielding, etc. 2) Ultra-Thin Non-Oriented Electrical Steel Strips: "ST Series" This series exhibits nearly uniform magnetic properties in all directions. It significantly suppresses eddy current loss within motors and demonstrates excellent low-loss characteristics across the high-frequency range of 400Hz to 20,000Hz, contributing significantly to higher efficiency and miniaturization of motor designs. Applications: High-speed motors for drones, electric compressor motors, high-speed medical motors, cryogenic moto...
