AZ31 Magnesium Rod (ASTM B80-13/DIN EN 1753) for Sacrificial Anode & Industrial Applications

AZ31 magnesium alloy bar, a flagship product of Huona New Material, is a high-performance wrought magnesium alloy rod engineered for lightweight structural applications. Composed of magnesium (Mg) as the base metal, with aluminum (Al) and zinc (Zn) as key alloying elements, it balances excellent mechanical strength, good ductility, and ultra-low density (only ~1.78 g/cm³--about 35% lighter than aluminum alloys). This combination makes it an ideal alternative to heavier metals in industries prioritizing weight reduction, while Huona's advanced extrusion and heat-treatment processes ensure consistent quality and dimensional precision across all batches.

• Alloy Grade: AZ31 (Mg-Al-Zn series magnesium alloy)
• International Standards: Complies with ASTM B107/B107M, EN 1753, and GB/T 5153
• Form: Round bar (standard); custom profiles (square, hexagonal) available
• Manufacturer: Huona New Material, certified to ISO 9001 for aerospace-grade quality

AZ31 magnesium alloy bar outperforms traditional structural materials in critical lightweight scenarios:

• Ultra-Lightweight: Density of 1.78 g/cm³, enabling 30-40% weight reduction compared to 6061 aluminum and 75% vs. carbon steel--ideal for fuel efficiency in automotive/aerospace.
• Good Mechanical Balance: Tensile strength of 240-280 MPa and elongation of 10-15% (T4 temper), striking a balance between strength and formability for bending, machining, and welding.
• High Stiffness-to-Weight Ratio: Specific modulus (E/ρ) of ~45 GPa*cm³/g, surpassing many aluminum alloys for structural stability in lightweight frames.
• Corrosion Resistance: Naturally forms a protective oxide layer; optional surface treatments (chromate conversion, anodizing) from Huona further enhance resistance to moisture and industrial environments.
• Eco-Friendly: 100% recyclable with low energy consumption during production, aligning with global sustainability goals.

• Automotive: Lightweight components (steering columns, seat frames, transmission housings) to reduce vehicle weight and improve fuel efficiency.
• Aerospace & Defense: Secondary structural parts (cargo bay frames, interior panels) and drone airframes, where weight savings boost payload capacity.
• Consumer Electronics: Laptop/tablet chassis, camera tripods, and power tool housings--balancing portability and durability.
• Medical Devices: Lightweight surgical instruments and mobility aid components (wheelchair frames) for ease of use.
• Industrial Machinery: Light-duty structural parts (conveyor rollers, robotic arms) to reduce energy consumption during operation.
