Product Description
AZ31B Magnesium Alloy Sheet
Product Overview
AZ31B magnesium alloy sheet from Huona is a lightweight, high-strength structural material, ideal for weight-sensitive applications. It combines low density with excellent strength-to-weight ratio, good machinability, and moderate corrosion resistance, making it a preferred choice in aerospace, automotive, and consumer electronics industries. Manufactured via precision rolling and controlled annealing, this sheet delivers consistent mechanical properties and uniform surface quality.
Core Specifications
- Alloy Grade: AZ31B (Magnesium-Aluminum-Zinc Alloy)
- Typical Dimensions: 1.0mm × 300mm × 500mm (custom thickness 0.5–6.0mm, width/length available)
- Composition: Mg 96%, Al 3%, Zn 1%, trace Mn
- Density: ~1.78 g/cm³ (≈2/3 the density of aluminum, 1/4 of steel)
- Mechanical Properties (Temper O):
- Tensile Strength: ≥290 MPa
- Yield Strength: ≥150 MPa
- Elongation: ≥15%
- Temper: O (annealed) / H24 (strain-hardened and partially annealed)
- Compliance: ASTM B90, GB/T 5153, RoHS 2.0
Key Advantages
1. Ultra-Lightweight with High Strength-to-Weight Ratio
AZ31B offers exceptional weight reduction without sacrificing structural integrity, making it ideal for applications where every gram counts. It enables significant fuel savings in transportation and improved portability in consumer products.
2. Excellent Machinability & Formability
The alloy’s uniform grain structure allows for precision cutting, stamping, bending, and CNC machining with minimal tool wear. It can be easily formed into complex shapes, supporting custom component designs.
3. Moderate Corrosion Resistance
When properly treated, AZ31B exhibits good resistance to atmospheric corrosion. Its natural oxide layer provides basic protection, and optional surface treatments (anodizing, chromate conversion) can further enhance durability in harsh environments.
4. Good Thermal & Electrical Conductivity
AZ31B offers better thermal conductivity than many engineering plastics, making it suitable for heat-dissipating components in electronics and lighting systems. It also maintains sufficient electrical conductivity for certain grounding and shielding applications.
5. Versatile Processability & Surface Treatment
The sheet supports a wide range of surface treatments, including anodizing, painting, and plating, allowing for both functional and aesthetic customization. It is also weldable using TIG/MIG processes, enabling assembly into larger structures.
