2024 aluminum vs 7075 is Al-Cu-Mg system hard aluminum alloy, can be heat treated and strengthened. The performance of the 2024 and 7075 aluminum alloy has significant differences according to the different heat treatment states, after solution treatment, the natural aging state has high tensile strength and toughness, artificial aging has high yield strength and corrosion resistance. The comprehensive mechanical properties and high temperature resistance are excellent. High-temperature softening tendency is small, can be used as heat parts alloy pressure processing and mechanical processing performance is good, varieties include plate, strip, clad aluminum plate, tube various aluminum products.
2024 aluminum is one of the aluminum alloys widely used in aviation and machinery industries. The plates and profiles of this alloy have been successfully applied to structural parts of aircraft, such as skins, wing beams, etc., and can be trucked for wheel rims, screw mechanism products, small hardware and other various structural parts. For the thin plate used in the state used in the natural state, the clad aluminum plate should be used for the parts with strict requirements of corrosion resistance, and for the parts that can maintain the precision fit for a long time under the requirement of high temperature, it should be used after stabilization.
7075 aluminum alloy is Al-Zn-Mg-Cu system high-strength hard aluminum alloy, can be heat-treated to strengthen. The alloy's static strength is higher than 2024 aluminum alloy, and the fatigue strength is similar to 2024 aluminum alloy, and its room temperature forming performance is good in the annealed or solution heat treatment state, and can be processed into various varieties of products, its weldability is poor, not easy to gas welding, but resistance welding.
7075 aluminum alloy belongs to the high-strength super hard aluminum widely used at home and abroad, is the main material for aircraft structural parts, suitable for manufacturing aircraft skin, wing beam, spacer, landing gear parts, and hydraulic system components. 7075 aluminium alloy commonly used heat treatment state is T6, T73, T76, T6 temper of high strength, but the fracture toughness is low, more sensitive to stress corrosion, with the lateral subject to continuous stress conditions of use should be carefully considered, in this case can be replaced with T73, because T73 temper has a fairly high fracture toughness and excellent stress corrosion resistance and resistance to stripping layer corrosion performance. The T76 temper has good overall performance, its strength is higher than the T73 temper, followed by stress corrosion resistance is better than the T6 state. Usually the appropriate temper should be selected according to the conditions of use.
