Aluminum 7075 T6 Pipe manufacturer
On this page,you would find the detail specification about 7075 pipes,including chemical and mechanical property and size availability.
7075 aluminium alloy (AA7075) also known as Al Zn5.5MgCu,is an aluminium alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility, high strength, toughness, and good resistance to fatigue. It is more susceptible to embrittlement than many other aluminium alloys because of microsegregation, but has significantly better corrosion resistance than the alloys from the 2000 series. It is one of the most commonly used aluminium alloys for highly stressed structural applications and has been extensively used in aircraft structural parts

Heat Treatment for 7075 Aluminum
| Heat Treatment/Temper | Process Description | Effect on Properties |
|---|---|---|
| O (Annealed) | Heating to ~415°C (775°F), then slow cooling | Softest condition, best formability, low strength |
| T6 (Solution Heat-Treated + Artificial Aging) | 1. Solution heat treatment at ~480°C (900°F), then quenching in water 2. Aging at ~120°C (250°F) for 24 hours | Highest strength but lower stress-corrosion resistance |
| T73 (Overaged for Stress-Corrosion Resistance) | 1. Solution heat treatment at ~480°C (900°F) 2. Aging at ~108°C (225°F) for 8 hours, then 163°C (325°F) for 24 hours | Lower strength than T6, better corrosion resistance |
| T76 (Intermediate Between T6 & T73) | Similar to T73, but aged for a shorter time | Moderate strength, improved corrosion resistance |
| T651 (Stress-Relieved T6) | T6 treatment + minor stretching (1-3%) to relieve residual stresses | High strength, reduced internal stress for machining |
| T7351 (Stress-Relieved T73) | T73 treatment + minor stretching (1-3%) | High corrosion resistance with reduced stress |
Why Aluminum 7075
7075 is a cold-treated forged aluminum alloy that has a higher strength than regular steel. 7075 is one of the most powerful aluminum alloys for commercial applications. 7075 aluminum alloy has a compact structure and strong corrosion resistance, especially suitable for aviation and marine plates. It has general corrosion resistance, good mechanical properties, and anodic reaction. The fine grains result in better drilling performance in deep holes and improved tool wear resistance
