Features:

Parameter Category Specific Indicators Key Description
Density 2.7 g/cm³ Approximately 1/3 the density of steel, significantly reducing weight for transport and installation loads.
Tensile Strength 70–700 MPa Varies by grade: 5052 reaches 230MPa, 6061-T6 exceeds 300MPa after heat treatment, and 7075 grade reaches up to 700MPa.
Specific Strength 70–80 MPa·cm³/g Far higher than Q235 steel (45–50 MPa·cm³/g), offering superior load-bearing capacity at equal weight.
Corrosion Resistance Naturally forms dense Al₂O₃ oxide film Passes 1000+ hours of salt spray testing without corrosion, providing long-term protection in coastal, humid, or chemical environments without additional coatings.
Thermal/Electrical Conductivity Thermal conductivity: 237 W/(m·K); Electrical conductivity: ~61% IACS 3x higher thermal conductivity and 2x higher electrical conductivity than stainless steel, ideal for heat dissipation and conductive applications.
Machinability Elongation ≥10% Easily cut, bent, stamped, or laser-cut with precision up to ±0.1mm, supporting complex shaping.
Surface Quality Ra 0.4μm–1.6μm Available in mirror, brushed, fluorocarbon coating, and other finishes for both decorative and industrial use.
Environmental Performance 100% recyclable; recycled aluminum uses only 5% of the energy of primary aluminum Meets green manufacturing standards for a low-carbon lifecycle.
3. Architectural & Decoration Applications
1. Building Curtain Walls
3000/5000 series aluminum plates, treated with fluorocarbon coating, offer excellent wind pressure resistance and weatherability. At just 1/5 the weight of stone, they reduce structural load and improve installation efficiency by over 40%, making them a premium choice for modern high-rise and commercial building facades.
2. Interior Decoration
Used for ceilings, wall panels, and signage, aluminum plates can be finished with brushed, wood-grain, or other decorative treatments to create a high-end aesthetic suitable for commercial spaces and luxury residences. Their lightweight nature simplifies installation and reduces structural stress.
3. Roofing & Canopies
The low weight of aluminum plates minimizes building structural loads, while their A2-class fire resistance ensures no toxic gas release at high temperatures. Combined with outstanding corrosion resistance, they provide a durable, safe solution for roofing and outdoor canopies.
4. Key Advantages Over Steel Plates
1. Significant Lightweight Advantage
With a density of 2.7 g/cm³ (only 1/3 that of steel at 7.85 g/cm³), aluminum plates are over 65% lighter than steel plates of the same volume. In construction, this drastically reduces structural bearing requirements and cuts installation time by over 30%.
2. Superior Corrosion Resistance
Steel plates are prone to rust and require regular anti-corrosion treatments (e.g., galvanizing, painting), leading to high maintenance costs. Aluminum plates form a dense, protective aluminum oxide layer naturally, resisting moisture, acid rain, and salt spray without additional coatings. They last over 15 years in coastal environments and offer 5x better corrosion resistance than steel in chemical settings, reducing lifecycle maintenance costs by 80%.
3. Enhanced Performance & Versatility
Thermal/Electrical Conductivity: Aluminum outperforms steel in heat and electricity conduction, making it ideal for temperature-regulating and conductive design elements.
Machining Flexibility: Excellent plasticity allows easy bending, stamping, and laser cutting to create complex, curved shapes—far more versatile than steel, which has high forming costs.
Sustainability: 100% recyclable with no performance loss in recycled material, and recycled aluminum uses only 5% of the energy required for primary production, making it far more eco-friendly than steel.
Aesthetic Appeal: Anodizing, fluorocarbon coating, and other finishes deliver a wide range of colors and textures, offering superior decorative potential compared to steel.
4. Lower Lifecycle Cost
While the initial material cost of aluminum is slightly higher than that of ordinary steel, the total lifecycle cost is over 60% lower due to reduced transportation costs (≈40%), zero corrosion maintenance, and a service life 2–3 times longer than steel.
5. Customization & Service
We offer full customization of aluminum plates across all grades (1000–7000 series) and dimensions (thickness 0.2–150mm, width 200–2000mm). Surface treatments include mirror, brushed, fluorocarbon coating, and anodizing. Our technical team provides one-stop support for material selection and processing guidance, serving global clients in over 30 countries with high-quality, cost-effective solutions.
