——Technical Analysis by Huahui New Materials Technology
Aluminum-magnesium-manganese plates are made from AA3004/5052 series aluminum alloys, processed through precision rolling, surface treatment, and coating technologies. Their key characteristics include:
| Performance Indicator | Technical Parameter | Advantages Over Color-Coated Steel |
|---|---|---|
| Density | 2.7g/cm³ (1/3 of steel) | Lightweight, reducing building load |
| Tensile Strength | ≥150MPa (AA3004), ≥270MPa (6061) | Higher strength-to-weight ratio, superior wind resistance |
| Corrosion Resistance | Salt spray test >1500h (ASTM B117) | 5052 alloy withstands coastal climates, lifespan ≥50 years |
| Weatherability | QUV aging >2000h (GB/T 18950) | UV resistance, long-term color/fade resistance |
| Formability | Bending radius ≥t²/(1.5δ) (t: thickness) | Easy shaping for complex architectural designs |
Material Essence
Al-Mg-Manganese Plates: Aluminum alloy substrate with inherent corrosion resistance, requiring no additional galvanization.
Color-Coated Steel: Relies on zinc coatings for protection, prone to rusting in acid rain environments.
Performance Comparison
Strength & Lifespan: Al-Mg-Manganese plates have 30% higher tensile strength and lifespan exceeding 50 years; color-coated steel typically lasts 20–30 years.
Environmental Impact: 100% recyclable aluminum reduces carbon emissions by 40% compared to steel.
Application Scope
Al-Mg-Manganese Plates: High-end curtain walls, roofing, subway carriages, etc., where durability is critical.
Color-Coated Steel: Temporary constructions, low-cost workshops, etc.
Base Material Selection
AA3004: Balanced strength and corrosion resistance for general climates.
5052-H34: Marine-grade alloy with chloride ion resistance, ideal for coastal projects.
Surface Treatment
Anodizing: Enhances corrosion resistance (salt spray >5000h) and supports colored pigmentation (ΔE≤1.5).
Fluorocarbon Coating: 25-year weatherability, self-cleaning properties (contact angle >110°), and reduced maintenance.
Precision Fabrication
CNC Bending: Minimum radius of 0.5mm for complex curved surfaces.
Welding Technology: TIG/MIG welding ensures weld strength ≥90% of base material, eliminating thermal deformation.
High-End Architectural Curtain Walls
Case: A 5000㎡ aluminum-magnesium-manganese curtain wall in Shanghai reduced energy consumption by 30% compared to glass panels, with wind resistance of 4.5kPa/m².
Rail Transit
Subway Carriages: 0.8mm perforated plates for sound absorption (NRR≥20dB), suitable for humid and dusty environments.
Industrial Buildings
Huahui Case: A 1.2mm roof panel project in Shandong shortened construction time by 20% and cut costs by 15%.
Cost-Effective Long-Term Value
Slightly higher initial cost but 50% lower lifecycle maintenance expenses.
Superior Material Performance
5052-H34 alloy outperforms galvanized steel in coastal and high-humidity regions.
