Product Description
AZ31B Magnesium Plate 20×30×3700mm
AZ31B magnesium plate (20mm thickness × 30mm width × 3700mm length) from Huona New Material is a high-strength wrought magnesium alloy engineered through hot rolling, solution treatment, and artificial aging processes. This commercial magnesium alloy offers an optimal balance of ultra-lightweight properties (density 1.78g/cm³), excellent mechanical strength, and superior formability, making it ideal for lightweight components in aerospace, automotive, and 3C electronics applications.
Standard Designations & Material Foundation
- Alloy Grade: AZ31B (Mg-Al-Zn system; equivalent to ASTM B90/B90M, UNS M11311)
- Key Specification: 20mm (thickness) × 30mm (width) × 3700mm (length); tolerance: thickness ±0.5mm, width ±0.8mm, length ±10mm
- Chemical Composition (wt%): Al: 2.5-3.5%; Zn: 0.6-1.4%; Mn: 0.2-1.0%; Mg: balance (≥94%)
- Compliant Standards: ASTM B90/B90M, GB/T 5153-2016 (wrought magnesium alloy plates), RoHS 2.0
- Manufacturer: Huona New Material, certified to ISO 9001 and IATF 16949
Key Advantages
Ultra-Lightweight & High-Strength Balance
- Weight Reduction Advantage: Density of 1.78g/cm³ is 33% lighter than aluminum and 78% lighter than steel—a 20×30×3700mm plate weighs only ~4.0kg (vs. 6.1kg for aluminum)
- Mechanical Strength: Tensile strength ≥230 MPa, yield strength ≥160 MPa (T6 temper), elongation ≥10%
Optimized Specification for Long Structural Parts
- Long-Length Adaptability: 3700mm length avoids splicing of long components, reducing assembly costs
- Dimensional Uniformity: Thickness tolerance ±0.5mm and flatness ≤1mm/m ensure consistent processing accuracy
Excellent Processability & Corrosion Resistance
- Formability: Good cold/hot working performance—supports stamping, bending, and CNC machining
- Corrosion Resistance: Surface treated with chemical conversion coating (optional), passing 240-hour ASTM B117 salt spray testing
