2024 Aluminium alloy Al Cu4 Mg1 (AU4G1) TEMPER T3511

Product catalog summary
Overview: The document provides technical specifications and performance properties of the Aluminium alloy Al Cu4 Mg1 (AU4G1) in the T351 temper. This alloy is primarily used in aeronautical applications due to its mechanical properties.
Mechanical Characteristics: The alloy exhibits good mechanical characteristics due to structural hardening, especially in quenched, tempered, or aged-hardened states. It is chosen for aeronautical applications because of its high toughness and resistance to crack propagation.
Heat and Corrosion Resistance: The alloy has good resistance to heat but lacks resistance to corrosion in corrosive atmospheres due to the presence of copper.
Applications: Alloy 2024 is widely used in aeronautical construction and engineering, particularly for parts subjected to stress.
Mechanical Properties:
  • Modulus of Elasticity: 73,000 MPa
  • Thermal Stress Coefficient: 22.9 x 10-6/K
  • Electric Conductivity: 30% IACS
  • Thermal Conductivity: 120 W/m.K
  • Specific Gravity: 2.77
  • Hardness: 104 - 122 HB
  • Elongation: 5 - 11%
  • Limit of Elasticity (Rp 0.2): 250 - 290 MPa
  • Tensile Strength: 360 - 430 MPa
Chemical Composition (Weight %):
  • Aluminium (Al): Balance
  • Copper (Cu): 3.80 - 4.90
  • Magnesium (Mg): 1.20 - 1.80
  • Manganese (Mn): 0.30 - 0.90
  • Iron (Fe): Max 0.50
  • Silicon (Si): Max 0.50
  • Chromium (Cr): Max 0.10
  • Zinc (Zn): Max 0.25
  • Titanium (Ti): Max 0.15
  • Other elements: Max 0.15

2024 Aluminium alloy Al Cu4 Mg1 (AU4G1) TEMPER T3511-1

Performance properties and aptitudes : Mechanical characteristics by structural hardening. Good mechanical characteristics, in particular in the quenched, tempered or aged-hardened state. It is because of these mechanical characteristics that this alloy has been chosen for aeronautical applications. Good resistance to heat. No resistance to corrosion in a corrosive atmosphere because of the presence of copper. In general, used for parts subjected to stresses. Alloy 2024 has good mechanical characteristics because of a higher magnesium level. It has good toughness and resistance to crack propagation. 2024 is very much used in aeronautical construction and in engineering. Non-contractual document 10 October 2011 edition
