2A11 Aluminum Rod Bar
2A11 aluminum rod bar, also known as “standard hard aluminum alloy” (formerly LY11), is a high-strength, heat-treatable aluminum-copper-magnesium alloy. It is one of the earliest and most widely used hard aluminum alloys, favored for its excellent balance between strength, formability, and machinability. This alloy possesses excellent mechanical properties, making it suitable for load-bearing applications. It is particularly renowned for its good spot welding performance and acceptable gas welding characteristics. 2A11 is a versatile material suitable for various industrial and aerospace components.
| Advantage | Description |
| High Strength-to-Weight Ratio | 2A11 offers significantly higher strength than 1000 and 3000 series alloys, making it ideal for weight-sensitive applications. |
| Good Machinability | In the T4 or T6 temper, 2A11 has good machinability, allowing for high-speed cutting and production of complex parts with good surface finish. |
| Heat-Treatable | The alloy can be heat-treated to achieve a range of strength levels, from the tough T4 temper to the high-strength T6 temper, providing flexibility for different design requirements. |
| Weldability | 2A11 has good spot welding characteristics and can be gas welded, though it may be prone to cracking in certain high-heat welding processes. |
Our 2A11 aluminum alloy bar rod conform to international standards such as ASTM B221, GB/T 3191-2010, GB/T 3190-2020. 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.
