7075 aluminum sheet is a high-performance alloy from the Al-Zn-Mg-Cu series, highly regarded as one of the strongest commercial aluminum alloys available, ideal for demanding applications. As a leading China supplier and manufacturer, we provide this premium material to meet your industrial needs.

Core Characteristics

Exceptional strength-to-weight ratio: Offers strength comparable to low-carbon steel at just one-third of the weight.

Excellent machinability: Designed for easy cutting, milling, drilling, and tapping, ensuring consistent processing performance.

Limited formability: While it has lower ductility than 6082 or 3104 alloys, it is suitable for simple bending applications rather than deep drawing or complex forming.

Corrosion resistance: Susceptible to stress corrosion cracking in harsh environments; however, the T73 temper significantly enhances resistance to this issue.

Anodizing capabilities: Develops a dense, uniform oxide layer that supports coloring, catering to both protective and aesthetic requirements.

 

Key Mechanical Properties

Tensile strength: ≥ 540MPa (varies slightly by temper, with T6 temper being the most common).

Yield strength: ≥ 480MPa (providing excellent load-bearing capacity for structural applications).

Elongation: ≥ 11% (balancing ultra-high strength with moderate ductility).

Popular tempers: T6 (solution heat-treated and artificially aged, widely used), T651 (stress-relieved post-T6 for improved dimensional stability), T73 (offering enhanced corrosion resistance for severe environments).
