Chemical Composition Limits:
The document outlines the chemical composition limits for Alloy 2024, specifying the minimum and maximum weight percentages for elements such as Copper (Cu), Magnesium (Mg), Manganese (Mn), Silicon (Si), Iron (Fe), Zinc (Zn), Titanium (Ti), and Chromium (Cr). For instance, Copper ranges from 3.80% to 4.90%, and Magnesium from 1.20% to 1.80%.
Typical Physical Properties:
The average coefficient of thermal expansion is 12.9 (68-212°F per F), and the melting range is approximately 935-1180°F. Thermal conductivity and electrical conductivity values are provided for different tempers.
Mechanical Properties:
The document provides typical US mechanical properties for various tempers of Alloy 2024, including tensile strength, hardness, shear strength, electrical conductivity, fatigue endurance limit, and modulus of elasticity. For example, the ultimate tensile strength for a T3 temper is 70 KSI with a yield strength of 50 KSI.
Important Notes:
It is noted that the typical properties listed are averages and not guaranteed, as they vary based on size, product forms, and manufacturing methods. These data are intended for comparison purposes and should not be used as engineering requirements or for design purposes.
