Key Core Advantages (Centered on Extruded Process & Lightweight Design)

1. Ultra-Light & Stable Mechanical Properties

• Low Density: Density of only 1.77g/cm³ (1/4 of steel, 2/3 of aluminum), achieving maximum lightweight while maintaining excellent structural support.
• Extrusion Benefits: Extrusion process provides a refined, uniform grain structure, resulting in tensile strength ≥230MPa, yield strength ≥150MPa, and elongation ≥12%, with improved toughness and fatigue resistance compared to rolled products.

2. Excellent Formability & Processability

• Balanced Ductility: Elongation ≥12% in H112 condition, suitable for precision machining (turning/milling/drilling) and moderate forming operations.
• Machinability: Easy to machine 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. Uniform Microstructure & Performance

• Refined Grain Structure: Precision extrusion ensures consistent mechanical properties across the entire plate, reducing performance variability.
• 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.
