What is Aircraft Grade Aluminum 7075?

Aviation-grade aluminum 7075 is a high-strength aluminum alloy, commonly used is 7075-T6 aluminum, T6 refers to its tempering, or the state of the material after heat treatment and cooling. In addition to its use in aerospace, 7075 aluminum is commonly used in other high-stress applications.

7075 Aluminum is mainly composed of zinc with small amounts of magnesium, copper and chromium. Its high strength-to-weight ratio, excellent fatigue strength and good machinability make it a popular choice for aircraft structural components such as fuselage frames, spars and landing gear components.

7075 Aerospace Aluminum Plate Specifications

7075 aerospace aluminum plate is a high-strength aluminum alloy commonly used in aircraft and aerospace applications. Here are some typical specifications for 7075 aluminum plate :

• Thickness : 0.25 - 6 inches (6.35-152.4 mm)
• Width : up to 60 inches (1524 mm)
• Length : up to 144 inches (3657.6 mm)
• Elongation : 6% to 11%

Note that these specifications can vary depending on the manufacturer and specific application requirements. It is important to consult the manufacturer's specifications and standards to ensure that the 7075 aluminum plate meets the necessary requirements for its intended use.

7 Notes on Using 7075 Aerospace Aluminum Plate

1. High Strength, Low Toughness

7075 aluminum alloy is known for its high strength, but it has relatively low toughness compared to some other aluminum alloys. This means it can be susceptible to cracking or fracture in applications where impact resistance is critical. Careful design and analysis are required to ensure that the alloy's high strength is effectively utilized without compromising safety.

2. Machinability

While 7075 aluminum is highly valued for its strength, it can be more challenging to machine compared to other aluminum alloys. It can quickly dull cutting tools and requires specific techniques and tooling to achieve desired shapes and tolerances. Proper lubrication and cooling are essential during machining to prevent overheating.

3. Weldability

7075 aluminum alloy is generally considered difficult to weld. Its high zinc content can lead to cracking during welding, particularly in applications that require high-strength welds. Welding 7075 typically requires specialized techniques and may involve preheating and post-weld heat treatment to reduce the risk of cracking.

4. Corrosion Resistance

While 7075 aluminum has good corrosion resistance in many environments, it is not as corrosion-resistant as some other aluminum alloys, such as 6061. Proper surface treatments, coatings, and corrosion prevention measures are essential in applications where exposure to harsh conditions or moisture is a concern.

5. Material Cost

7075 aluminum is one of the more expensive aluminum alloys due to its high zinc content, which contributes to its strength. The cost of raw material can be a significant factor in the overall project budget.

6. Surface Finish and Appearance

Achieving a smooth and aesthetically pleasing surface finish on 7075 aluminum can be challenging due to its hardness. Specialized polishing and finishing processes may be required to meet cosmetic requirements.

7. Fatigue Resistance

While 7075 aluminum has excellent strength properties, it can be sensitive to fatigue failure, particularly when exposed to cyclic loading. Proper design, stress analysis, and inspections are crucial to manage fatigue concerns.
