Chinese Standard High Strength Corrosion Resistance 5A06 Aluminum Alloy Sheet
5A06 aluminum alloy sheet is a corrosion-resistant Al-Mg-Mn series alloy, known for its high
strength, excellent weldability, and outstanding corrosion resistance, making it particularly
suitable for marine environments, chemical equipment, and cryogenic applications.
Key Properties
♦ Chemical Composition
Al-Mg-Mn series alloy containing Mg (5.8-6.8%) and Mn (0.5-0.8%), with trace Ti and Be
♦ Mechanical Properties
Tensile strength: ≥315 MPa (H112 state), up to 400 MPa after cold working
♦ Elongation
≥15% (excellent for cold forming)
♦ Low-temperature performance
Maintains good toughness even at -196°C
♦ Corrosion Resistance
Excellent seawater corrosion resistance
Outstanding stress corrosion cracking resistance
Main Advantages
✔ Superior corrosion resistance (especially marine environments)
✔ High strength-to-weight ratio (density ~2.64 g/cm³)
✔ Excellent weldability with minimal post-weld treatment
✔ Good cryogenic performance for LNG/extreme cold applications
Common Thicknesses
Marine/Shipbuilding: 3-25 mm (hulls, decks), 1-6 mm (bulkheads)
Chemical Industry: 2-12 mm (storage tanks, pipelines)
Transportation: 1.5-8 mm (railway carriages, truck bodies)
Other Applications: 0.5-3 mm (decorative panels)
Typical Applications
