High Strength 200- 260mm Super Thick Aluminum Alloy Plate


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.
