High Strength 200- 260mm Super Thick Aluminum Alloy Plate
Key Performance Advantages
1) Lightweight Superiority
• Exceptional Strength-to-Weight Ratio
7XXX series (e.g., 7050) offers tensile strength up to 570MPa with density of only 2.8g/cm³ -
1.8× higher specific strength than Q345 steel, ideal for aerospace/military weight reduction.
• Structural Efficiency
Single thick plates eliminate multi-layer welding, avoiding joint weakening (e.g., 200mm 5083-H321
ship decks reduce fasteners by 50%).
2) Environmental Resistance
• Extreme Temperature Stability
5XXX series (e.g., 5083) maintains toughness at -196℃ (LNG storage) with no cold brittleness.
2XXX series (e.g., 2219) withstands short-term 300℃ exposure (rocket engine compartments).
• Corrosion Resistance
Natural corrosion rate <0.02mm/year (5083 in marine environments), eliminating protective coatings.
Nuclear-grade 5052 resists radiation oxidation with >40-year service life.
3) Manufacturing Benefits
• Machinability
6XXX series (6082-T6) achieves surface roughness Ra≤1.6μm with 1/3 the tool wear of steel.
• Weldability
2219 plates achieve 90% base metal strength using VPPA welding.
