7075-T651 Aluminum Alloy:Properties and Applications

Dec 31, 2025

If you are sourcing 7075-T651 aluminum or other aluminum alloy grades, choosing a supplier with deep industry expertise and proven experience is essential. At GNEE, we work closely with reputable aluminum mills known for their consistency, precision, and material quality. By applying the same strict quality standards to our upstream partners as we do to our own operations, GNEE ensures customers receive reliable, high-performance 7075-T651 aluminum plate products that meet demanding industrial requirements.

7075 Aluminum Properties & Availability

7075 aluminum alloy is widely recognized for its exceptional strength-to-weight ratio, which surpasses that of many steels. Zinc is the primary alloying element, giving 7075 its outstanding mechanical strength. This alloy is available in multiple tempers, including 7075-T651, 7075-T7351, and 7075-O, with each temper offering distinct performance characteristics.

At GNEE, we stock 7075-T651 aluminum plate in thicknesses starting from 0.25 inches up to 8.0 inches, ensuring availability for a wide range of applications. The T651 temper undergoes solution heat treatment, artificial aging, and controlled stretching for stress relief, providing improved dimensional stability and excellent machinability.

Industry Applications

As part of the 7000 series aluminum alloys, 7075 is suitable for numerous high-performance applications where light weight, toughness, and strength are critical. Due to its excellent mechanical properties and machinability, 7075 aluminum is extensively used in:

Automotive components

Aircraft and aerospace structures

High-stress mechanical parts

Gears and shafts

Structural components

Fuse parts and precision assemblies

Manufacturers and end users value 7075 aluminum for its ability to withstand extreme stress while maintaining a reduced overall weight. GNEE supplies premium 7075-T651 aluminum plate to customers who demand consistent quality and dependable performance.

Machining and Welding Considerations

7075 aluminum alloy offers good machinability, making it suitable for precision machining operations. However, general welding is not recommended for this alloy. Resistance welding may produce acceptable results, but arc welding or gas welding can reduce the alloy's inherent corrosion resistance and negatively impact performance.

With decades of experience supplying high-quality aluminum materials, GNEE supports industrial customers with both standard aluminum stock and customized aluminum solutions. Whether your project requires precision aluminum plate, specialty alloys, or tailored specifications, GNEE is equipped to meet your needs with reliability and expertise.
