7075 Aluminum Plate Sheet
7075 aluminum plate is an ultra-hard aluminum alloy with aluminum, zinc, magnesium, and copper as the main alloying elements. It offers significant advantages in engineering and manufacturing, but requires proper handling to ensure its performance.
1. Material Characteristics
- Extremely high strength and hardness: 7075 aluminum plate has strength and hardness comparable to steel, making it one of the strongest commercial aluminum alloys.
- Corrosion resistance: It has moderate corrosion resistance but requires coating with aluminum or other protective treatments before use.
- Good mechanical performance: Provides excellent mechanical performance and anodic reaction.
2. Processing and Machining
- Cold-worked forged alloy: The 7075 aluminum plate is cold-worked and forged to enhance its strength and hardness.
- Heat treatment strengthening: The aluminum alloy can be further strengthened through heat treatment.
3. Advantages and Disadvantages
| Advantages and Disadvantages | Detailed Description |
| Advantages | High strength and hardness, suitable for high-load applications |
| Good mechanical performance and anodic reaction | |

Features of 7075 Aluminum Plate
- Excellent Fatigue Strength: 7075 aluminum alloy exhibits outstanding fatigue strength, making it suitable for structural components that need to withstand repeated stress.
- Machinability: The machinability of this alloy is moderate. Although it is slightly worse than some lower-strength aluminum alloys, it still provides good machinability under reasonable conditions.
- Corrosion Resistance: Compared to other aluminum alloys, 7075 has lower corrosion resistance. Therefore, corrosion protection measures are necessary, especially in humid or corrosive environments.
- Strength: 7075 aluminum alloy has very high strength, comparable to many types of steel, making it suitable for high-strength applications.
- Plasticity After Solution Treatment: After solution treatment, 7075 aluminum alloy exhibits good plasticity, meeting various complex forming requirements.
- Heat Treatment Strengthening: 7075 aluminum alloy can significantly increase its strength during heat treatment, especially after aging treatment, which has a particularly notable strengthening effect.
- Low-Temperature Strength: Below 150°C, 7075 aluminum alloy maintains high strength, with particularly outstanding strength performance in low-temperature environments.
- Welding Performance: The welding performance of 7075 aluminum alloy is poor, making it difficult to weld. Therefore, welding is usually avoided or other connection methods are used in structural design.
- Stress Corrosion Cracking Tendency: 7075 aluminum alloy has a tendency for stress corrosion cracking, which means cracks may appear under certain environmental conditions. To improve stress corrosion cracking resistance, a two-step aging treatment can be used.
- Plasticity in Annealed and Just-Quenched States: In annealed and just-quenched states, the plasticity of 7075 aluminum alloy is slightly lower than that of 2A12 aluminum alloy but better than 7A04 aluminum alloy. Therefore, the plasticity performance of 7075 aluminum alloy in these states is relatively good, though attention is still needed to process requirements.

7075 Aluminum Plate Applications
7075 aluminum plate is used to manufacture aircraft structures and other high-stress structural parts that require high strength and strong corrosion resistance, such as upper and lower wing panels, girders, bulkheads, etc. After solution treatment, it has good plasticity and is particularly effective in heat treatment. It has high strength below 150°C and has particularly good low-temperature strength. It has poor welding performance and a tendency to stress corrosion cracking. Double-stage aging can improve SCC resistance.
