Magnesium (Mg): The Future of Ultra-Lightweight & High Strength
“Ultra-lightweight, high-strength innovation realized with the lightest metal“
Magnesium is the lightest structural metal and is a key material driving weight reduction across industries.
Finetriphos Magnesium (PPM) leads the future of advanced industries by combining the inherent lightness of magnesium with exceptional strength and ductility through its unrivaled technology.
1. Pure Mg
Magnesium is one of the most abundant resources on Earth, serving as the foundation for a sustainable industrial ecosystem.
Atomic Information: Atomic Number 12, Atomic Mass 24.3, Hexagonal Close-Quantum (HCP) Structure
Infinite Resource: The 8th most abundant element in the Earth's crust and the 3rd most abundant in seawater. Extracted from ores and seawater (electrolytic and thermal reduction methods).
The key to lightweighting: With a specific gravity of 1.74, the lightest material among structural metals is transformed into a high-performance industrial material through PPM's technology.
2. Overwhelming lightness and high strength
“It’s 33% lighter than aluminum and 75% lighter than steel, yet offers exceptional strength-to-weight ratios.”
Magnesium is a key solution for achieving both the ultra-lightweight and high-performance goals of modern high-tech industries.
3. Benefits of Magnesium
In addition to its physical properties, magnesium plates possess a variety of high-performance properties required in industrial settings.
