2024-T3, 2024-t4 and 2024-T351 Properties

The aircraft aluminum alloys mainly include high-strength/ultra-high-strength and high-toughness Al-Zn-Mg-Cu series (7xxx series), medium-high strength and damage-resistant Al-Cu series (2xxx series), and medium-strength weldable Al-Mg-Si series (6xxx series), as well as high-strength and high-ratio lightweight Al-Li alloys and a small amount of other aluminum alloys.

As a heat-treatable high-strength Al-Cu-Mg series aluminum alloy, 2024 aluminum sheet is widely used to make various high-load parts and components due to its high strength and high toughness characteristics, excellent heat resistance and good fatigue resistance such as aircraft skins, vehicle hubs, ship propellers, etc.

2024 thick aluminum sheets are mainly used in fuselages, wings, shear floors and webs, and other structural parts with high strength requirements. Artificial aging can be used to improve the corrosion resistance, heat resistance and yield strength of 2024 alloy, but the plasticity and fatigue fracture resistance will be reduced, and the fatigue crack growth rate will also be accelerated.

The hardness of 2024-H112 is around HB85. The hardness of 2024-T4 is HB120~145. The hardness of 2024-T351 is HB120~145. The hardness of 2024-0 is around HB40. 2024 aluminum alloy is commonly used in T3 and T4 tempers, which have high plasticity, fatigue life, fracture toughness and resistance to fatigue crack growth, but poor corrosion resistance. What are 2024-t3 aluminum properties?

2024-T3 aluminum plate has high strength and excellent fatigue resistance. Welding is generally not recommended. Typical uses for 2024-T3 aluminum sheet are fuselage and wing skins, roofs, aircraft structures, and airframe repair and restoration. Its ultimate strength is 62,000 PSI and shear strength is 40,000 PSI.

2025-T351 alloy has high toughness and fracture toughness, but relatively low yield strength. 2024-t4 has the highest ductility compared to the other variants of 2024 aluminum. The heat treatment state commonly used in aerospace components is the T42 (solid solution + natural aging) state. For example, many 2024 aluminum alloys used in Boeing and Airbus airplanes are in the T42 temper.

Haomei Aluminum mainly has 7075 and 2024 thick aluminum plates. Welcome to leave message to inquire 7075, 2024-t3 and 2024-t4 aluminum sheet. During Spring Festival, we still will reply you in time.
