2A14 Aluminum Bar

The 2A14 aluminum bar is a high-strength aluminum alloy with a relatively high copper content, offering excellent strength and thermal stability. It possesses good machinability, electrical resistivity, and performance in spot welding and seam welding. This alloy can be heat-treated for further strengthening and exhibits good extrusion effects. It is primarily used in high-load industries such as aerospace, automotive, bridges, and military applications.

Popular types of 2A14 aluminum bars

Chemical composition of 2A14 aluminum bar

The 2A14 series aluminum bars have the highest copper content, approximately 3.9-4.8%, which gives them extremely high hardness. They are suitable for applications that require high strength, high hardness, and resistance to high temperatures.

Mechanical properties of 2A14 aluminum bar

Heat treatment specifications of 2A14 aluminum bar

Homogenization annealing: Heat to 475–490°C; hold for 12–14 hours; furnace cool.  

Complete annealing: Heat to 350–400°C; holding time varies from 30–120 minutes depending on the effective thickness; cool to 300°C at a rate of 30–50°C/hour, then air cool.  

Rapid annealing: Heat to 350–460°C; holding time of 30–120 minutes; air cool.  

Quenching and aging: Quench at 495–505°C, water cool; natural aging at room temperature for 96 hours.

Characteristics of 2A14 aluminum bar

• High strength and hardness: After heat treatment, the strength of 2A14 aluminum bar can exceed 470 MPa.
• Good heat resistance: Suitable for use in working environments up to 150°C.
• Good weldability: The 2A14 alloy has excellent spot and seam welding performance, making it ideal for manufacturing complex structural components.
• Poor corrosion resistance: Due to the weak corrosion resistance of 2A14 aluminum, users must perform anodizing or other protective treatments when used outdoors or in humid environments.
• Poor machinability: In the annealed state, the material has low machinability and requires specific cutting tools and processes.
