2A16 Aluminum Rod Bar
2A16 aluminum rod bar is a heat-treatable Al-Cu-Mn aluminum alloy renowned for its exceptional high-temperature strength and creep resistance. While possessing moderate strength at room temperature, it exhibits excellent mechanical stability and load-bearing capacity at ambient temperatures ranging from 250°C to 350°C. This alloy is characterized by excellent ductility under hot working conditions, good weldability, and the ability to be strengthened through heat treatment. It is a crucial material for applications requiring components to withstand sustained thermal stress without significant deformation.
| Advantage | Description |
| Exceptional High-Temperature Strength | 2A16 maintains its mechanical properties much better than standard aluminum alloys at temperatures up to 350°C, making it ideal for thermal applications. |
| Good Weldability | The alloy exhibits good spot welding, seam welding, and argon arc welding performance with a low tendency for cracking, allowing for the fabrication of complex welded structures. |
| Excellent Hot Workability | In the hot state, 2A16 has high plasticity and no significant extrusion effect, making it suitable for forging and hot forming processes. |
| Heat-Treatable | Can be strengthened through solution heat treatment and artificial aging (T6 temper) to achieve high strength levels. |
We can also provide Material Testing Certificates (MTC) and third-party inspection reports upon request to ensure quality assurance and traceability for your critical applications. We offer a variety of thicknesses and widths to meet diverse application needs, and provide standard and custom sizes to meet specific design requirements.
