Product Description
The 2024 aluminum plate is a high-strength aluminum–copper alloy (Al–Cu–Mg system) renowned for its exceptional fatigue resistance, excellent strength-to-weight ratio, and good machinability.
It is typically supplied in T3, T4, and T351 tempers, making it a preferred material for aerospace structures, transportation equipment, and other high-performance applications requiring light weight and superior mechanical strength.
Typical thickness ranges from 0.25 mm to 127 mm, with standard sizes like 4×8 ft or customized dimensions upon request. Available finishes include mill finish, Alclad (clad), or anodized surfaces for enhanced corrosion protection.
Complying with international standards such as ASTM B209 and AMS 4037, Huashou Steel’s 2024 aluminum plate delivers a tensile strength up to 470 MPa while maintaining excellent workability and fatigue resistance.

Values may vary slightly depending on thickness and manufacturing standard (ASTM B209 / AMS 4037 / AMS-QQ-A-250/4).
The 2024 aluminum plate is primarily used where high strength, excellent fatigue resistance, and light weight are critical. It is one of the most widely used alloys in aerospace and defense industries.
✈️ Aerospace Structures: Fuselage frames, wing tension members, ribs, and bulkheads.
Transportation Equipment: Automotive chassis, truck wheels, and structural panels.
Military & Defense: Missile parts, armored vehicle panels, and precision machined components.
Industrial Machinery: High-load gears, fasteners, and lightweight machine frames.
Marine & Sporting Goods: Lightweight, high-strength parts exposed to dynamic stresses.
Because 2024 aluminum has limited corrosion resistance, it is often supplied as Alclad (clad) or anodized to enhance surface protection.
High Strength: Outstanding tensile and yield strength, ideal for structural and aerospace use.
Excellent Fatigue Resistance: Performs exceptionally under cyclic loading conditions.
Good Machinability: Easy to machine and form with precise dimensional accuracy.
Moderate Workability: Can be cold-formed in annealed condition, then heat-treated.
Lower Corrosion Resistance: Typically used with Alclad or anodized surfaces for durability.
Heat Treatable Alloy: Properties can be improved via solution heat treatment and artificial aging.
Confirm the Required Temper:
Choose T3, T4, or T351 based on your strength and formability needs.
Select Suitable Surface Treatment:
Opt for Alclad or Anodized finishes if used in outdoor or marine environments.
Verify Standards & Certification:
Ensure compliance with ASTM B209, AMS-QQ-A-250/4, or EN 485, and request an MTC (Mill Test Certificate).
Specify Dimensions Clearly:
Provide exact thickness, width, and length for minimal waste and compatibility.
Plan for Processing Services:
Huashou Steel offers CNC cutting, precision machining, and custom processing to reduce lead time.
Evaluate Packaging & Logistics:
Confirm seaworthy export packaging and secure transport to ensure safe delivery.
