Product Core Attributes
Basic Product Attributes
- Alloy Series & Models: Covering 3105 (Al-Mn alloy), 5005 (Al-Mg alloy), 5052 (Al-Mg alloy), and 5083 (Al-Mg alloy) - four classic marine-grade aluminum alloys
- Product Form: Aluminum alloy sheet with customizable thickness (0.3mm-20mm), width (1000mm-2500mm), and length (2000mm-6000mm)
- Temper: O, H14, H18, H32, H34 (optional) with H32/H34 being most widely used for marine scenarios
- Marine Grade Certification: Complies with international marine standards (ASTM B209, EN 485, GB/T 3880)
- Surface Treatment: Mill finish (default), anodized, electrostatic spraying, or hot-dip galvanizing
Mechanical & Physical Attributes
- High Strength: Tensile strength ranges from 110MPa to 310MPa, yield strength 70MPa-260MPa
- Light Weight: Density approximately 2.7g/cm³, 30%-50% lighter than steel
- Corrosion Resistance: Strong resistance to seawater, salt spray, and humid marine atmosphere
- Thermal & Electrical Conductivity: Excellent thermal conductivity (120-200 W/(m*K)) and electrical conductivity
- Formability & Weldability: Easy to cut, bend, stamp, and weld with no cracking or deformation
