Key Core Advantages (Centered on Lightweight & Formability)
1. Ultra-Light & High Strength
- Low Density: Density of only 1.77g/cm³ (1/4 of steel, 2/3 of aluminum), achieving maximum lightweight while maintaining excellent structural support.
- High Specific Strength: Tensile strength ≥220MPa, yield strength ≥140MPa, with excellent load-bearing capacity for weight-sensitive applications.
2. Excellent Formability & Processability
- Good Ductility: Elongation ≥15% (annealed condition), suitable for stamping, bending, deep drawing, and other forming processes without cracking.
- Machinability: Easy to machine (turning/milling/drilling) with high surface finish, reducing processing time and cost.
3. Good Corrosion Resistance
- Natural Oxide Film: Dense magnesium oxide film formed on the surface, effectively resisting atmospheric and weak acid-base corrosion.
- Surface Treatment Compatibility: Supports anodizing, passivation, and painting for enhanced corrosion resistance in harsh environments.
4. Stable Mechanical Properties
- Uniform Microstructure: Precision rolling ensures uniform grain size and consistent mechanical properties across the entire sheet.
- Temperature Stability: Withstands service temperature from -40℃ to 150℃ (continuous), maintaining structural integrity without deformation.
5. Eco-Friendly & Sustainable
- 100% Recyclable: AZ31B magnesium alloy can be completely recycled and reused, with no heavy metal pollution, complying with green industrial development standards.
