2011 Aluminum Round Bar
2011 Aluminum Round Bar is a high-performance free-machining aluminum alloyfrom the 2000 series, specifically engineered for applications requiring exceptional machinability, superior surface finish, and high production efficiency. This heat-treatable copper-based alloycontains 5.0–6.0% copperwith additions of lead (0.2–0.6%) and bismuth (0.2–0.6%), which significantly enhance its machining characteristics by promoting chip breakability and reducing tool wear.
The industry widely recognizes 2011 aluminum as one of the most machinable aluminum alloys available, achieving machining speeds comparable to brass while maintaining aluminum’s lightweight advantages.

2011 Aluminum Round Bar Tempers
| Temper Type | Description |
|
T3 |
2011 T3 aluminum alloy undergoes solution heat treatment first, where it is heated to a high temperature and then rapidly cooled, allowing alloy elements to dissolve into the aluminum matrix. Manufacturers then further strengthen it through cold working to enhance hardness and strength. Finally, manufacturers carry out natural aging by leaving the material at room temperature for a period of time, allowing precipitates within the material to refine and improve mechanical properties. T3 temper aluminum alloys are suitable for applications requiring moderate strength and good machinability. |
| T6 | 2011 T6 aluminum alloy is first subjected to solution heat treatment, where it is heated to a high temperature and quickly cooled to ensure the alloy elements are fully dissolved. Then, we carry out artificial aging by heating the material to a specified temperature and holding it for a period of time, allowing the precipitates to refine and significantly increase strength. T6 temper aluminum alloys exhibit high strength and hardness, making them suitable for applications that require the handling of large loads and high strength. |
|
T8 |
2011 T8 aluminum alloy undergoes multiple steps including solution heat treatment, cold working, and artificial aging. First, the aluminum alloy is subjected to solution heat treatment, where it is heated to a high temperature and rapidly cooled to dissolve the alloy elements. Then, cold working further increases the material’s strength. Operators heat the aluminum alloy to a specified temperature. They hold it under controlled conditions for a period. This occurs during the artificial aging process. This allows the precipitates to refine. It also maximizes the strength. The T8 temper results in the alloy achieving its best strength. It also achieves its best hardness. This makes it ideal for high-precision applications. These applications require high strength and good machinability. |
