Nippon Kinzoku's Commitment to Eco-Conscious Manufacturing

In an era increasingly focused on environmental responsibility, Nippon Kinzoku Co., Ltd. is stepping up its efforts to promote sustainably produced electromagnetic steel bands. Positioned under the branding of "Fine Eco Metal®", their ultra-thin directional and non-directional electromagnetic steel bands, known as the GT and ST series, are at the forefront of this initiative. This product lineup aligns with the company’s strategic goal of contributing to a decarbonized society by offering high-efficiency materials that help reduce energy losses in electronic devices.

Background:

The demand for energy-efficient solutions is on the rise due to the push for electrification in machinery. Within this push, minimizing energy loss (referred to as iron loss) particularly in high-frequency applications has become increasingly critical. To address these challenges, Nippon Kinzoku and its group company, Nikkin Denki Kogyo, have leveraged their extensive experience in rolling technology and sophisticated heat treatment processes to achieve an unprecedented combination of "extreme thinness" alongside "superior magnetic properties"—an accomplishment that was once deemed unattainable with standard electromagnetic steel plates. This innovation allows them to accelerate their offerings to clients focusing on next-generation technology development.

Advantages of Using Ultra-Thin Electromagnetic Steel Bands:

The implementation of thinner electromagnetic steel bands yields several notable benefits, including:

• - Energy Efficiency: Reduced eddy current losses greatly enhance fuel and electricity efficiency, while mitigating overheating issues.
• - High-Frequency Capability: Their design supports high-speed rotation and powerful drives, making them suitable for high-speed motors and transformers operating in high-frequency domains.
• - Compact and Lightweight Design: These materials allow for the creation of more compact products while also shedding unnecessary weight, facilitating space-saving implementations.

Eddy currents are electric currents that generate within the electromagnetic steel band due to alternating magnetic fields, exacerbating iron losses and impacting performance negatively.

Product Lineup:

1. GT Series (Grain-Oriented Electrical Steel)

This series boasts exceptionally high magnetic attributes due to the alignment of crystal directions. Available in thicknesses ranging from 0.04mm to 0.10mm, the GT series significantly minimizes eddy current losses in high-frequency environments:

• - Thickness Options: 0.04mm(GT040), 0.05mm(GT050), 0.08mm(GT080), 0.10mm(GT100). Other thicknesses are available upon request.
• - Widths: 5mm to 305mm
• - Applications: Used in high-frequency transformers, reactors, pulse power supplies, and magnetic shielding.

2. ST Series (Non-Oriented Electrical Steel)

Designed to exhibit nearly uniform magnetic characteristics from all directions, the ST series drastically curtails eddy current losses in motors across a high-frequency range from 400Hz to 20,000Hz. This series plays a significant role in enhancing the efficiency and compactness of customer motors:

• - Thickness Options: 0.05mm(ST050), 0.08mm(ST080), 0.10mm(ST100), 0.15mm(ST150). Other thicknesses are available upon request.
• - Widths: 5mm to 300mm
• - Applications: Ideal for high-speed motors in drones, electric compressors, medical equipment, and ultra-low temperature applications.

Future Outlook:

Nippon Kinzoku recognizes the importance of contributing to sustainable manufacturing practices. Their exclusive "Fine Eco Metal®" certification identifies products with energy-saving capabilities, supporting groundbreaking developments in high-efficiency motors and future-oriented power electronics, among others. The company is committed to achieving net-zero CO₂ emissions by 2050 and actively works towards fostering a sustainable society through the provision of eco-friendly materials.
