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
