Aluminum Alloy 2024 Hardness

 2024 aluminum alloy has excellent mechanical properties and is widely used in aerospace and automobile manufacturing. 2024 aluminum alloy has excellent strength and performs well under normal and low temperature conditions, making it suitable for applications requiring high strength.

Aluminum alloy 2024 t3 was introduced by Alcoa in 1931. Its Ai-Cu-Mg structural composition allows its yield strength to reach 5ksi, replacing 2017-T4 as the main 2XXX series aerospace alloy. 2024 has relatively good fatigue resistance, especially in thick plates, making it suitable for most aircraft structural applications.

2024 aluminum alloy is easy to process such as extrusion, forging, and casting, and is suitable for the manufacture of complex parts. 2024 aluminum alloy has certain high temperature resistance and is suitable for applications in some high temperature environments.

Under normal circumstances, after T3 state heat treatment, the hardness of 2024 aluminum alloy is about HB120. After more stringent heat treatment in the T351 state or T4 state, the hardness may be higher, reaching around HB140.

Common tempers of 2024 aluminum sheet

1. T4 temper: 2024 aluminum alloy undergoes natural aging treatment after solid solution treatment. In the T4 state, the alloy has high strength and good corrosion resistance, but the hardness and strength are relatively low, making it suitable for applications requiring corrosion resistance.

2. T6 temper: 2024 aluminum alloy is artificially aged after solid solution treatment. In the T6 state, the alloy has high strength and hardness while maintaining good toughness, and is suitable for applications requiring high strength and hardness, such as aerospace and high-performance structural component manufacturing.

3. T3 temper: 2024 aluminum alloy is aged directly after solution treatment. In the T3 state, the alloy has good strength and plasticity and is suitable for situations requiring high strength and good processability.

4. T8 temper: After solid solution treatment, the 2024 aluminum alloy is age hardened at a higher temperature. In the T8 state, the alloy obtains higher strength and hardness and is suitable for special applications requiring extremely high strength and hardness.

2xxx Aluminum Alloys: 2024 Aluminum Sheet

 2xxx aluminum alloys belong to the Al-Cu-Mg alloy, which is called high-strength hard aluminum and is the most widely used structural aluminum alloy. The tensile strength of 2xx series aluminum alloy is 400~500 MPa, which is lower than the room temperature strength of 7xxx series aluminum alloy, but its heat resistance, fatigue characteristics, especially fatigue crack propagation resistance are better than those of 7xxx series aluminum alloy.

2000 series aluminum alloys have higher strength, and the alloy strength of 2xxx grades can compete with steel. However, due to differences in copper content, the strength and corrosion resistance of this series vary within a wide range to meet different needs.

Among them, the corrosion resistance of alloys with lower copper content is close to that of rust-proof aluminum; the strength of alloys with higher copper content is close to that of hard aluminum, which is actually equivalent to increasing the silicon content on the basis of hard aluminum.

Among the 2000 series aluminum alloys, the 2024 alloy invented in 1939 is the more commonly used one. 2024 alloy has brought huge changes to the structure and performance of aircraft, and also laid the foundation for the development of 2000 aluminum alloys.

2024 has a density of 2.78 g/cm 3 (0.1 lb/in 3 ), a conductivity of 30% IACS, and a Young's modulus of 73 GPa (10.6 Msi) in all states at 500 °C (932 °F). The composition of 2024 aluminum alloy roughly includes 4.3-4.5% copper, 0.5-0.6% manganese, 1.3-1.5% magnesium and less than 0.5% silicon, zinc, nickel, chromium, lead and bismuth.

2024 aluminum sheet has high strength and certain heat resistance, and can be used as working parts below 150℃. At temperatures above 125°C, the strength of 2024 alloy is higher than that of 7075 aluminum plate. The formability is relatively good in the hot state, annealed and newly quenched states, and the heat treatment strengthening effect is significant, but the heat treatment process requirements are strict.

The common tempers of 2024 aluminum is T3, T351 and T4. 2024 t351 aluminum has high plasticity, fatigue life, fracture toughness and resistance to fatigue crack growth, but poor corrosion resistance. This alloy thick plate is mainly used in fuselages, wings, shear floors and webs, and other structural parts with high strength requirements.

What Are the 2024 Aluminum Properties

 2024 aircraft aluminum belongs to the Al-Cu-Mg high strength deformed aluminum alloy, which is widely used in aviation, aerospace and other military products. The heat treatment state often used in aviation components is T42 (Solid Solution + Natural Aging). For example, many 2024 aluminum alloys used in aviation products such as Boeing and Airbus are in T42.

2024 aluminum alloy The compressive strength of 2024 aluminum alloy is higher than that of 7075 aluminum alloy. The forming characteristics are better under quenching and new heat treatment conditions, and the heat treatment process enhancement can achieve an ideal effect. The corrosion resistance is weak, but it can be reasonably maintained with pure aluminum coating.

2024 aluminum properties vary significantly depending on the heat treatment state. After solution treatment, the natural aging state has higher tensile strength and toughness, and the artificial aging state has higher yield strength and corrosion resistance.

Its comprehensive mechanical properties and high-temperature creep resistance are excellent, and the high-temperature softening tendency is small. 2024 alloy is commonly used in aircraft structures, bolts, truck wheels, aircraft propeller components and many other parts.

With the development of the aviation industry, the requirements for the high temperature resistance of materials are getting higher and higher. in an emergency, a high temperature of 204 ℃ may appear in the short-term dive state. This kind of creep under long-term thermal environment will affect the material structure of the aircraft.

The related research shows that showed that: compared with peak aging, the precipitated phase in the supersaturated solid solution increased the creep resistance of the alloy during the under-aging process. After underaging treatment, the steady-state creep rate of 2024 aluminum alloy is significantly reduced.
