7075 aluminum block
7075 aluminum alloy is an aluminum alloy with zinc as the main alloying element, but it has much better corrosion resistance than 2000 alloys. Its relatively high cost limits its usage.
The 7075 aluminum block belongs to the Al-Zn-Mg-Cu super hard alloy category and is a cold-forged alloy, known for its high strength and hardness. This alloy exhibits excellent mechanical properties and anodic reaction, making it a typical aluminum alloy material used in the aerospace industry, molds, engines, and equipment.
7075 aluminum blocks are produced in various states, including 7075-0, 7075-T6, and 7075-T651.
-
7075-O
Unprocessed state with lower strength, suitable for applications requiring good formability.
-
7075-T6
Age-hardened state with the highest strength, suitable for high-stress components.
-
7075-T651
Solution-treated and age-hardened, reducing internal stress, with a balance of strength and toughness, suitable for precision machining and high-load applications.
7075 aluminum alloy is a high-strength material with excellent performance. Although it is relatively expensive, its outstanding mechanical properties and fatigue strength allow for widespread use in aerospace, molds, and high-load equipment. When selecting 7075 aluminum blocks, it is important to consider their corrosion resistance and machining characteristics to ensure suitability for specific application environments.

Characteristics of 7075 Aluminum Block
- 1. Strength: The strength of 7075 aluminum alloy is comparable to that of many steels, particularly after heat treatment, exhibiting extremely high tensile and yield strength.
- 2. Hardness: It has high hardness, allowing it to withstand significant loads.
- 3. Fatigue Strength: 7075 aluminum alloy has excellent fatigue strength, making it suitable for structural components subjected to repeated loads.
- 4. Corrosion Resistance: Compared to other aluminum alloys (such as the 7000 series), the corrosion resistance of 7075 is relatively poorer, but it is still better than that of 2000 series aluminum alloys. Anodizing treatment can enhance its corrosion resistance.
- 5. Machinability: Although the machinability of 7075 is average, it can be precision machined under the right conditions.
