The 2000 series aluminum alloy has excellent temperature resistance and is mainly used in aerospace high-temperature components. The excellent temperature resistance is mainly due to the complex chemical composition and phase composition of the 2000 series aluminum alloy.
It can maintain good strength stability and process performance at high temperatures. It is mostly used for heat-resistant parts and heat-resistant weldable structural parts and forgings working in the temperature range of 150 to 250°C.
Aluminum alloy 2024 is one of the strongest 2xxx alloys, with copper and magnesium being the main elements. The most commonly used temper designs include 2024T3, 2024T351, 2024T4, and 2024 T6. The corrosion resistance of the 2xxx series alloys is not as good as that of most other aluminum alloys, and intergranular corrosion may occur under certain conditions.
2024 T3 aluminum plate is considered an aircraft alloy due to its strength and also has excellent fatigue resistance properties. Its ultimate strength is 62,000 PSI and shear strength is 40,000 PSI.
Welding is generally not recommended. Typical uses for 2024-T3 aluminum sheet are fuselage and wing skins, roofs, aircraft structures.
2024-t351 aluminum has high strength, good cutting performance, high strength, heat resistance, good spot welding, and significant heat treatment strengthening effect. Anodizing and painting methods are used or an aluminum layer is added to the surface to improve its resistance. It is mainly used for aircraft skeleton components, rivets, wing spars, truck hubs, propeller components, bulkheads and other structural parts as well as working parts within 150℃.
2024 t4 is solution treated at foundry and naturally aged.2024-T4 hardness is: HB120~145. Its Brinell hardness is of 120,71Gpa. Its tensile strength is 469 Mpa, yield strength is 324 Mpa, modulus of elasticity is 73.1 Gpa. Its electrical conductivity is 30% IACS.
