- Mechanical Properties of Aluminum 2024:
Grade 2024 is perfect for structural applications where weight reductions are crucial because of its exceptional strength-to-weight ratio. Additionally, it has outstanding formability, weldability, and fatigue strength.
| Property | 2024-T3 | 2024-T4, T351 | 2024-T851 |
|---|---|---|---|
| Tensile Strength | 483 MPa | 70000 psi | 469 MPa | 68000 psi | >=455 MPa | 66000 psi |
| Yield Strength | 345 MPa | 50000 psi | 324 MPa | 47000 psi | >=400 MPa | 58000 psi |
| Modulus of Elasticity | 73.1 GPa| 10600 ksi | 73.1 GPa| 10600 ksi | 72.4 GPa | 10500 ksi |
- Applications for Aluminum 2024:
Grade 2024 is a heat-treatable, extremely strong, and light alloy. It is the perfect material for military and aerospace applications because of its strength and stiffness. Because of its exceptional wear resistance and machinability, it is also frequently found in bicycles, boats, sailplanes, and tools and molds. Its strength-to-weight ratio is another reason for its popularity. The aluminum 2024 alloy is also suitable for use in pressure vessels, tankage, and cryogenic applications where enhanced resistance to creep deformation at low temperatures is required. With all of these characteristics and applications, aluminum 2024 has established itself as one of the most adaptable alloys on the market right now.
- Corrosion Resistance:
The protective oxide film of alloy 2024 shields the metal surface from further oxidation, giving it exceptional resistance to corrosion. Because of this, it is perfect for usage in severe situations like saltwater or others where corrosion resistance is essential.
- Heat Resistance:
Aluminum 2024 is appropriate for use in high-temperature applications like exhaust systems or engine components since it can tolerate temperatures up to 350°C without experiencing any appreciable loss in strength or ductility.
- Heat Treatment:
Depending on the needed mechanical qualities for the final product, Aluminum 2024 can be heat treated using either solution treating or precipitation hardening process with ease.
- Machining:
Standard cutting tools like HSS drills, carbide-tipped drills, taps, etc., can be used to easily mill aluminum 2024 using traditional CNC equipment. It is easily machined into complex shapes using standard machining processes.
- Welding:
Filler metals containing silicon, magnesium, or zinc alloys can be used in TIG welding procedures to join aluminum 2042, or they can be joined using MIG welding techniques. However, extreme heat input may result in cracking during cooling, therefore care should be used when welding aluminum 2042.
- In summary
Because of its many applications, aluminum alloy 2024 is one of the most popular ones on the market right now. Aluminum 2024 can readily meet almost any application need, from structural components demanding high strength-to-weight ratios to electronic components requiring electrical conductivity. Because of its superior resilience to heat and corrosion, it can be used in even the most extreme conditions where other materials could break down too soon from exposure to corrosive substances and intense temperatures. When choosing materials for their projects, engineers should always consider aluminium 2024 as a versatile alloy due to its easy machinability, weldability, and good mechanical qualities.
