Properties of 2024 Aluminum
The 2024 aluminum has about five series that we’re going to consider. Despite variances in some properties, most of the features are just close. Let’s have a deep look into the properties.
This series has aluminum as its major components. In addition, the 2024 aluminum has other components like Chromium, Copper, Iron, Magnesium, and Manganese. There are other tiny metals that may be considered insignificant due to their low percentage composition.
The yield and ultimate tensile strength is 75.8 and 186 MPa respectively. Besides, the 2024-O aluminum gives a 20% elongation at break for 1.6 mm thickness. For alloys that are 12.7mm thick, the elongation at break extends to 22%. Besides, this type of 2024 aluminum has a machinability of 30% and fatigue strength of 89.6.
The shear modulus and strength are 28 GPa and 124 MPa respectively. In addition, this series melts at between 502 and 638 degrees Celsius. Even at that, its thermal conductivity is 193 W/M-K. Also, the 2024 aluminum with O temper has an annealing temperature of 413 degrees Celsius and solution temperature of 256 degrees Celsius.
The 2024-T3 aluminum has an annealing and solution temperatures of 413 and 256 Degrees Celsius. Besides, the 2024 aluminum has a majority composition of aluminum which can constitute up to 94.7% of the alloy. Other components that make a small composition of the alloy include Chromium, Copper, Iron, and Magnesium. These together gives the 2024 aluminum a density of about 2.78g/cc.
With a notched tensile strength of 379 MPa and ultimate 483 MPa, the 2024T3 aluminum’s yield TS is 345 MPa. With that it breaks at elongation of 18%+. This may be due to its modulus of elasticity which stands at 73.1 GPa and Ultimate bearing strength of 855 MPa. Besides, the 2024-t3 aluminum has a bearing yield strength of 524 MPa.
The above features make it easy for manufacturers of fastening devices, missile parts, and computer parts among others apply this 2024 aluminum in their development. The alloy has also been used to make couplings and fuse parts.
Additional features of this 2024 aluminum include machinability of 70%, thermal conductivity of 121 W/m-K, and fatigue strength of 138 MPa. Also, 2024-T3 aluminum has shear modulus and strength of 28 and 283 MPa respectively. Finally, the alloy has a specific heat capacity of 0.875J/g-degrees Celsius.
2024- T4 Aluminum
This is an interesting alloy with a varying ultimate tensile strength ranging between 395 and 579 MPa. This is dependent of a number of factors. Conversely, the 2024-T4 aluminum has a yield TS of 260-421 MPa again dependent of various factors.
Other properties include annealing and solution temperatures of 413 and 493 degrees Celsius. On top of that, the 2024-T3 aluminum has a specific heat capacity of 0.875J/g- Degrees Celsius. With its thermal conductivity at 121 W/m-K, the alloy’s melting point is between 502 and 638 Degrees Celsius.
The 2024-T4 aluminum has most of its properties identical to 2024-T351. And that’s why they’re mostly used interchangeably. Going on, the alloy has an electrical resistivity of 0.00000582 ohm-cm and machinability of 70%. To conclude, this 2024 aluminum has shear modulus and strength of 28 GPa and 283 MPa.
With all the above features, the 2024T4 aluminum is commonly used to make aircraft fittings, couplings, missile parts, pistons, and rectifier parts among others.
