TOKYO, Japan: Nippon Kinzoku Co. Ltd 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’.
‘Fine Eco Metal’ is a brand name for their proprietary ‘Eco-Product” series, certified based on their own environmental standards.
Amid the global movement toward a decarbonised society, there is an increasing demand for the electrification and higher efficiency of equipment. This has intensified the need to minimise energy loss (core loss), particularly in high-frequency ranges.
Leveraging years of proprietary rolling and advanced heat treatment technologies, the companies 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’, the companies aim to accelerate their solutions for customers developing next-generation technologies.
By aligning the crystal grain orientation in a specific direction, the Ultra-Thin Grain-Oriented Electrical Steel Strips: “GT 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.
It can be used in high-frequency transformers, reactors, pulse power supplies, magnetic shielding, etc.
The ultra-thin non-oriented electrical steel strips: “ST 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.
It is applicable in high-speed motors for drones, electric compressor motors, high-speed medical motors, cryogenic motors, etc.
Through the expansion of these products, the companies aim to empower innovative development in high-efficiency motors, next-generation power electronics, and high-frequency transformers.
