2024 Aluminum Plate is primarily used in applications that require high strength, excellent fatigue resistance, and good machinability. It is one of the most common aluminum alloys in the aerospace and defense industries due to its outstanding strength-to-weight ratio. Typical uses include:
Aerospace structures: aircraft fuselage frames, wing tension members, ribs, and bulkheads.
Transportation equipment: truck wheels, automotive chassis, and structural panels.
Military and defense components: missile parts, armored vehicle panels, and precision machined parts.
Industrial machinery: high-load gears, fasteners, and machine frames requiring both strength and light weight.
Marine and sporting goods: parts exposed to dynamic stress but requiring weight reduction.
Because 2024 alloy has limited corrosion resistance, it is often used with cladding (Alclad) or anodized surface treatment for protection in demanding environments.
Confirm the Required Temper: Choose the appropriate temper such as T3, T4, or T351 based on your strength and formability requirements. Aerospace and structural applications typically prefer T3/T351 for their superior mechanical strength.
Select Suitable Surface Treatment: Since 2024 alloy has limited corrosion resistance, request Alclad or Anodized surfaces if the material will be used in outdoor or marine environments.
Verify Standards and Certification: Ensure that the material meets international specifications such as ASTM B209, AMS-QQ-A-250/4, or EN 485, and obtain a Mill Test Certificate (MTC) for traceability.
Specify Dimensions Clearly: Provide exact thickness, width, and length to reduce material waste and guarantee compatibility with your production needs.
