2017-T4 aluminum alloy is a temper of 2017 aluminum, subjected to solution heat treatment and natural aging (T4 temper). This alloy is an aluminum-copper system with high strength, good corrosion resistance, and excellent mechanical properties. 2017 aluminum in the T4 temper has higher ductility and formability, making it easier to perform complex deep processing and forming compared to other tempers (such as T6).
The primary alloying element of 2017 aluminum alloy is copper, and it also contains small amounts of manganese, silicon, magnesium, iron, and chromium. Its chemical composition gives it good strength and corrosion resistance, making it particularly useful in aerospace and other high-strength applications.
| Element | Composition(%) |
| Al | REM |
| Si | 0.20-0.80 |
| Fe | ≤0.70 |
| Cu | 3.50-4.50 |
| Mn | 0.40-1.0 |
| Mg | 0.40-0.80 |
| Cr | ≤0.10 |
| Zn | ≤0.25 |
| Ti | ≤0.15 |
| other(each) | ≤0.05 |
| other(total) | ≤0.15 |
The T4 temper is achieved by solution heat treating the alloy to a specific temperature and then rapidly cooling it. This dissolves the solute elements in the matrix, followed by natural aging, which gradually increases the hardness of the material while maintaining high ductility. 2017 aluminum in the T4 temper strikes a good balance between strength and ductility.

| Yield Strength | Approximately 260 MPa |
| Tensile Strength | High, suitable for structural parts subject to high tensile forces |
| Elongation | 18% |
| Characteristics | Better ductility, suitable for deep processing and complex forming |
High Ductility: Due to natural aging, 2017 aluminum in the T4 temper exhibits high ductility, making it perform excellently during processing. It can undergo multiple forming operations without sacrificing strength, which is crucial for the production of complex parts.
Excellent Machinability: 2017 aluminum in the T4 temper is suitable for various machining processes, including deep drawing, stamping, and precision machining. It can withstand high tensile forces and undergo complex shape deformation.
Suitable for Welding: While 2017 aluminum alloy generally has poor weldability, the T4 temper shows improved welding performance, making it suitable for high-energy welding methods.
Although 2017 aluminum alloy generally has poor weldability, 2017 aluminum in the T4 temper performs somewhat better during welding. Special attention must be paid to the performance changes in the heat-affected zone. Using appropriate welding methods (such as TIG or MIG welding) can achieve good connections.
2017-T4 aluminum alloy excels in applications requiring high ductility, formability, and complex forming. It is widely used in aerospace, transport vehicles, and precision industrial components. Although its strength is lower than the T6 temper, its excellent machinability and formability give it a clear advantage in certain specific applications.
