7049 aluminum alloy vs 7075 aluminum alloy: comparison and analysis
7049 Aluminum Alloy is a high-strength forged aluminum alloy with exceptional stress corrosion cracking resistance, ideal for parts requiring high static and fatigue strength. It is particularly suited for aerospace and missile applications, including landing gear, gearboxes, and hydraulic cylinders.
7075 Aluminum Alloy is another well-known high-strength aluminum widely used in aerospace, recognized for its high strength, good mechanical properties, and moderate corrosion resistance. It's often chosen for lightweight structural components such as aircraft frames and body structures.
Chemical Composition
7049 contains higher levels of zinc and magnesium compared to 7075, providing an advantage in strength and stress corrosion resistance, though it is slightly less machinable than 7075.
Mechanical Properties
While both alloys exhibit similar tensile and yield strength, 7049 surpasses 7075 in stress corrosion resistance and toughness, whereas 7075 offers slightly better machinability.
Stress Corrosion Cracking Resistance
Stress corrosion resistance is one of the most significant differences between these two alloys.
- 7049-T6 is designed specifically for applications requiring higher stress corrosion resistance, making it an optimal choice for critical aircraft parts in humid environments.
- 7075-T6, despite its high strength, is more susceptible to stress corrosion cracks in humid or high-stress conditions, so for applications where extreme reliability is necessary, 7049 may be the preferred choice.
Applications
- 7049 is ideal for components requiring high static and fatigue strength, such as aircraft landing gear, gearboxes, hydraulic cylinders, and extrusions. Its corrosion resistance in high-stress environments makes it particularly suitable for critical parts in aircraft and missiles.
- 7075 is widely used in aircraft body structures, frames, and other areas demanding lightweight materials with high strength. It is typically chosen for high-strength applications where environmental corrosion is less of a concern.
For users with applications involving high-stress and high-corrosion environments like critical aerospace and missile components, 7049 aluminum alloy is ideal. Its toughness and stress corrosion resistance make it more reliable for high-risk environments. On the other hand, for applications requiring high strength with easier machinability, such as aircraft bodies or structural frames, 7075 aluminum alloy remains the industry's top choice due to its machinability and extensive use record.
