This table presents the key performance characteristics of 7150-T7751 aluminum alloy, making it suitable for aerospace and other high-strength applications.

7150 T7751 Aluminum Mechanical Properties

• Strength: The strength of 7150-T7751 aluminum plate is higher than that of traditional 7000 series aluminum alloys (such as 7075-T6), offering excellent tensile strength and yield strength. This makes it widely applicable in aerospace structural components, especially for parts requiring high-strength materials, such as wing spars, landing gear structures, and high-load-bearing components.
• Corrosion Resistance: Compared to traditional 7000 series aluminum alloys, 7150-T7751 aluminum exhibits slightly better corrosion resistance, particularly in resistance to exfoliation corrosion. It is suitable for long-term use of aircraft and other equipment under extreme environmental conditions.
• Fracture Toughness: Although it has excellent strength and corrosion resistance, the fracture toughness of 7150-T7751 is slightly lower than that of other 7000 series aluminum alloys. Therefore, this factor should be considered in design applications, especially when dealing with impacts or extreme loads.
• Fatigue Performance: The fatigue performance of 7150-T7751 aluminum plate is similar to other 7000 series aluminum alloys, but in the lower stress intensity range, the fatigue crack growth rate is higher. In the higher stress intensity range, its fatigue performance tends to be similar to other 7000 series alloys.

Machining and Applicability

• Dimensional Stability: After stress-relief stretching, 7150-T7751 aluminum plate no longer requires further straightening, but light straightening may be performed to meet standard tolerances. This provides high precision and good formability during the machining process.
• Machining Difficulty: Due to its high-strength characteristics, 7150-T7751 aluminum plate may require higher process requirements and tools during cutting, drilling, and other machining processes. Therefore, precision machining equipment is typically required.

7150-T7751 aluminum plate is a high-performance aluminum alloy, offering exceptional strength, good corrosion resistance, and relatively low fracture toughness. It is particularly suitable for high-load components in the aerospace sector, with outstanding exfoliation corrosion resistance.

7150 T7751 Aluminum Plate Manufacturing Process

• Solution Heat Treatment (T6): 7150-T7751 aluminum plate undergoes solution heat treatment to dissolve the strengthening phases in the alloy, thereby homogenizing the aluminum alloy's crystal structure.
• Stress-Relief Stretching: The stretching process is controlled to relieve internal stresses created during heat treatment, improving the dimensional stability and shape accuracy of the aluminum material.
• Artificial Aging: After stretching, the aluminum material undergoes artificial aging to further enhance its strength and corrosion resistance.

Compared to traditional T6 aluminum alloys, the T7751 temper offers superior exfoliation corrosion resistance. This improvement is primarily due to the optimized aging process, which enables the aluminum plate to effectively resist corrosion when exposed to harsh environmental conditions.
