NIPPON KINZOKU CO., LTD. (“the Company”) and its subsidiary, NIKKIN DENJI KOGYO CO., LTD., 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”.
\n“Fine Eco Metal” is a brand name for the Company’s proprietary “Eco-Product” series, certified based on our own environmental standards.<\/p>\n\"\"\n

Background and Objectives: Addressing the “Shift to Electrification”
\n<\/strong>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.
\n<\/strong>Leveraging years of proprietary rolling and advanced heat treatment technologies, the Company and NIKKIN DENJI KOGYO 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.<\/p>\n

Benefits of Adopting Ultra-Thin Electrical Steel Strips
\n<\/strong>By reducing the thickness of the electrical steel strip, eddy current loss (core loss) can be significantly lowered. Adopting our ultra-thin strips provides the following advantages:<\/p>\n\n\n\n\n\n\n\n

Product Lineup
\n<\/strong>\uff11) Ultra-Thin Grain-Oriented Electrical Steel Strips: “GT Series”
\n<\/strong>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.
\nThickness: 0.04mm (GT040), 0.05mm (GT050), 0.08mm (GT080), 0.10mm (GT100)
\n(Please consult us for other thickness requirements)
\nWidth: 5mm to 305mm
\nApplications: High-frequency transformers, reactors, pulse power supplies, magnetic shielding, etc.<\/p>\n\n\n\n\n\n\n\n\n
