As technology has advanced rapidly, the aviation industry has been racing to develop new materials with better performance to fit the demands of aviation technology. One notable development is the use of 7075 aluminum forgings, which have played a significant role in the aerospace industry. 7075 aluminum forging is notable for having superior strength, toughness, and corrosion resistance, which makes them ideal for fuselage frame applications, particularly in the aircraft web area. This article will discuss the chemical composition, mechanical properties, and advantages of 7075 aluminum forging in aircraft web.
Chemical Composition
The 7075 aluminum forging is an aluminum-zinc-magnesium-copper family alloy that belongs to the 7000 series of aluminum alloys. Its chemical composition is approximately as follows: 5.6 - 6.1% zinc, 2.1 - 2.5% magnesium, 1.2 - 1.6% copper, 0.3% iron, 0.4% silicon, 0.5% manganese, and 0.6% other elements. It is essential to regulate the composition of various elements in the alloy for control of its mechanical properties.
Mechanical Properties
7075 aluminum forging has incredible mechanical properties making it the material of choice for a wide range of applications in the aviation industry. The five most essential mechanical properties include strength, toughness, fatigue, stress corrosion resistance, and heat treatment response.
Strength: 7075 aluminum forging is a very high strength material, with a yield strength of 500 MPa and a tensile strength of 570 MPa. Therefore, it ensures the safety and durability of aircraft structures.
Toughness: 7075 aluminum forging has high toughness properties, with a fracture toughness of 18-25 MPa(m^0.5). When compared to other 7000 series alloys, 7075 aluminum forging has superior toughness and is better suited to more rigorous applications like web.
Fatigue: 7075 aluminum forging has high fatigue properties, with high endurance and crack avoidance qualities that make it a favorite in aircraft production.
Stress corrosion resistance: stress corrosion occurs when a material is exposed to an aggressive environment, such as saltwater and acid rain. When under such conditions, aluminum finds itself weakened. However, 7075 aluminum forging has moderate resistance to stress corrosion and has been proven to withstand these types of aggressive environments.
Heat treatment response: 7075 aluminum forgings are amenable to heat treatment, which makes it possible to optimize its microstructural characteristics, such as strength and toughness. For instance, 7075 aluminum forging has excellent response to the T73 temper compared to other aluminum alloys.
Advantages of 7075 aluminum forgings
7075 aluminum forging for aircraft web provides several advantages. Some of these advantages include;
1. High Strength-to-weight Ratio: 7075 aluminum forging has a high strength-to-weight ratio, which makes it ideal for the construction of lightweight aircraft structures.
