Magnesium alloy is gaining global attention for its incredibly low specific gravity approximately 1/4.5 that of steel and 1/2.5 that of titanium—while maintaining excellent specific strength, stiffness, and damping performance.

Target Markets: Beyond mobile PCs and high-end smartphones, we expect significant growth in the expanding XR device market.
XR (Extended Reality): A collective term for cutting-edge technologies—including Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR)—that merge physical and virtual environments to create immersive new experiences.
Sustainability & Mobility: In line with carbon-neutral goals, the demand for lightweight materials in transportation equipment—particularly in the aerospace and aviation sectors—is rapidly growing.

1. Development Background

As a pioneer in the rolling of magnesium alloys, we have led the industry since starting basic research in 1998. And in 2002, we became the first in Japan to achieve mass production using large-scale coils. This product is widely used in the chassis of personal computers and smartphones, among other applications.
And now by integrating our proprietary rolling and material development technologies, we have established mass-production technology for ultra-thin magnesium alloy foil, reaching a thickness as low as 0.044mm.

2. Key Features of Magnesium Alloy Foil

Our Magnesium Alloy Foil provides three distinct advantages for manufacturers:

Feature	Description	Benefit
1. Long-Length Coils	Achieved stable coil production even for difficult-to-roll magnesium.	Enables continuous processing (progressive/transfer press), boosting production efficiency.
2. High Strength & Formability	Maintains strength and plasticity comparable to thicker plates.	Can be press-formed with the same ease as standard-gauge magnesium alloys.
3. Superior Damping	Naturally absorbs vibrations and reduces noise.	Enhances audio quality in speaker diaphragms and improves stability in mobile device chassis.
