2017 T3 T4 Aircraft Aluminum Sheet Plate
2017 aluminum alloy is a high-strength aluminum alloy, primarily composed of lead and copper. It possesses excellent strength and good machinability, making it commonly used in aerospace and military applications.
2017 aluminum has poor weldability but can have its performance enhanced through heat treatment. Its corrosion resistance is relatively weak, often requiring surface treatments to improve it. The final applications of this alloy include aircraft structural components, gears, and other parts with high strength requirements.
2017 aluminum alloy is a heat-treatable high-strength aluminum alloy that belongs to the aluminum-copper-magnesium series (2xxx series). Its main components include 4-6% copper, 0.5-1.2% magnesium, and small amounts of manganese, silicon, and zinc. It has good strength, ductility, and machinability, with higher strength than 2011 aluminum alloy, while also demonstrating excellent corrosion resistance, fatigue resistance, and machinability. These characteristics make 2017 aluminum widely used in aerospace, military, automotive, and structural engineering fields, especially for components requiring high strength and lightweight.
In the aerospace field, 2017 aluminum alloy is commonly used to manufacture structural components of aircraft, such as wing ribs, fuselage frames, and landing gear. These components are required to withstand high stress and fatigue, so the high strength and excellent machinability of 2017 aluminum make it an ideal choice. 2017 aluminum is also used in the production of engine parts, suspension systems, and other components that bear high stress, which can effectively improve fuel efficiency and performance.
2017 aluminum alloy demonstrates good machinability during processing, ensuring efficiency and precision in manufacturing, particularly suited for producing complex parts with precise dimensions. However, its performance in welding is not as good as other aluminum alloys, especially in arc welding, where the welding process can reduce its corrosion resistance. Therefore, 2017 aluminum alloy is generally not used for welding applications and is better suited for resistance welding techniques.
After heat treatment (such as solution heat treatment and aging hardening), the performance of the alloy is further enhanced, with a significant increase in yield strength and tensile strength, allowing it to compete with certain high-strength steel alloys at a lower density.
Key advantages of 2017 aluminum alloy include:
- High strength: 2017 aluminum offers high strength, comparable to many steel alloys, especially at temperatures above 125°C, where its strength outperforms that of 7075 aluminum alloy.
- Excellent machinability: The alloy is easy to form, cut, and drill, maintaining good mechanical properties.
- Heat treatment capability: Through heat treatment, the strength and hardness of 2017 aluminum can be significantly improved.
- Corrosion resistance: Compared to other aluminum alloys, 2017 aluminum alloy has good corrosion resistance, extending the service life of the product.
These characteristics make 2017 aluminum widely used in aircraft structures, rivets, truck hubs, propeller parts, and other high-strength structural components. Additionally, 2017 aluminum is commonly used in the manufacture of military equipment, mechanical components, transportation vehicles, and some high-performance engineering structural parts.
2017 aluminum alloy is a high-performance, widely applicable medium-strength forged alloy, particularly suitable for manufacturing high-strength structural parts and high-stress components.

2017 T3 Aluminum Plate
The 2017-T3 aluminum plate is an aluminum-copper-magnesium alloy, known for its high strength and good heat resistance, making it suitable for applications in high-temperature environments. It undergoes heat treatment (such as age hardening) to enhance its strength, allowing it to operate below 150°C, and its strength can surpass that of 7075 aluminum alloy at temperatures exceeding 125°C. It is commonly used in aerospace, military equipment, and mechanical components that require high strength and high-temperature resistance.
2017 T4 Aluminum Plate
The 2017-T4 aluminum plate is an aluminum alloy that has undergone solution treatment followed by natural aging or low-temperature aging. It has good formability and fatigue resistance. Although its strength is slightly lower than that of the T3 state, it offers improved ductility and plasticity, making it suitable for applications requiring good formability and strong fatigue resistance, such as non-load-bearing components in aerospace, automotive body structures, and building structural components.
