What is 7075 Aluminum Alloy Forgings?

7075 Aluminum Alloy Forgings (7075 Aluminum Alloy) are high-performance aluminum products made from 7075 Aluminum Alloy through the forging process.7075 Alloy has zinc as the main alloying element (5.1-6.1%), supplemented by magnesium and copper, which provides ultra-high strength and excellent fatigue resistance. Southwest Aluminum (Kunshan) Co., Ltd. utilizes five 630-10,000 ton forging lines to produce 7075 forgings, such as forged bars and rings, which comply with AMS and ASTM standards and are widely used in scenarios requiring extremely high strength.

Characteristics of 7075 Aluminum Alloy Forgings

7075 forgings are known for the following properties:

Ultra-high strength: after T6 heat treatment, the tensile strength can reach 510-570 MPa, which is close to the level of some steels.

Lightweight: with a density of only 2.81 g/cm³, the weight is much lower than that of steel, making it suitable for weight reduction designs.

Fatigue resistance: Forging process refines grain size to improve durability.

Limited corrosion resistance: Compared to 6xxx series, the corrosion resistance is slightly inferior, but can be improved by surface treatment.

Southwest Aluminum combines heat treatment technology to ensure optimized performance of forgings.

Application Areas

7075 aluminum alloy forgings are used in aerospace for highly loaded components such as wing girders and landing gears, in the military industry to support armored structures, and in sports equipment (e.g., high-strength bicycle frames). Its high-strength and lightweight characteristics are a perfect fit for performance needs. Southwest Aluminum's (Kunshan) 10-meter forging ring technology further expands the potential of 7075 forgings for large-size parts.

Market Outlook and Emerging Trends

Aerospace demand (8% CAGR) and automotive lightweighting (7-8% CAGR) to drive 7075 forgings market growth by 2025. New information shows rising demand for China's low-orbit satellite program and electric vehicle battery frames, where the strength benefits of 7075 forgings are in focus. Southwest Aluminum (Kunshan) is seizing the opportunity with its 70,000 ton annual capacity and ISO9001 certification, while responding to the green manufacturing trend by optimizing its production process through ISO14001.

Summary

7075 aluminum alloy forgings serve aerospace, military and other fields with ultra-high strength and lightweight characteristics. Southwest Aluminum meets high standards with advanced forging processes. 2025 market is booming due to aerospace and lightweight boom, and the company provides efficient solutions to solidify its position in the industry.
