Which Aluminium Alloy Is Strongest

The aircraft aluminum alloys have the features of light specific gravity, high specific strength, low cost, easy processing, and corrosion resistance. It has long been an indispensable key structural material in the global aerospace field. Its usage accounts for approximately 40% to 70% of the weight of the aircraft body structure. It is widely used in aircraft main load-bearing frames, beams, wall panels, skin and other parts.

7xxx series and 2xxx series aluminum alloys have the largest usage, variety and specifications among all aviation aluminum alloys, and are the most representative aviation aluminum alloys. The aluminum alloys used in large aircraft structures in various countries around the world today are mainly 2024, 2224, 2324, 2424, 2524, 7075, 7475, 7050, 7150, 7055, 7085, etc.

7075 aluminum alloy is a kind of Al-Zn-Mg-Cu alloy. 7075 aluminum strength is very high and is better than mild steel, but it has ordinary corrosion resistance and good mechanical properties. Fine grains enable better deep drilling performance and enhanced tool wear resistance. Zn is the main alloy element in 7075. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with significant strengthening effect, making the heat treatment effect of this alloy far better than that of Al-Zn binary alloy.

7075 aluminum plates are stress-relieved and will not deform or warp after processing. All oversized and ultra-thick 7075 aluminum plates have been ultrasonically detected to ensure that there are no blisters and impurities. 7075 aluminum plates have high thermal conductivity, which can shorten the molding time and improve the quality of the products.

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 inside the 2000 series aluminum alloy, which can maintain good 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 150~250℃.

2024 aluminum alloy is a commonly used material in the current aircraft manufacturing process. It not only has high plasticity, but also has many advantages such as fatigue expansion resistance, heat resistance, and fracture toughness. 2024 aluminum alloy is mainly used in aircraft structures that require high strength, such as fuselage, wings, webs, etc. What are the aluminum alloy 2024 properties?

2024 aluminum is an Al-Cu-Mg aluminum alloy. The density of 2024 aluminum alloy is 2.73 g/cm. It can be strengthened through heat treatment and has medium plasticity in the quenched and freshly quenched states. Aluminum 2024 is divided into 2024-o, 2024-t3, 2024-t4, 2024-t5 and 2024-t351 according to the heat treatment temperature. The mechanical properties of these 2024 alloys may vary depending on the tempering of the material.
