Pursuit of excellence for 2A11 aluminum bars
In the production of 2A11 aluminum bars, we focus on the meticulous control of two key indicators: coarse grain rings and straightness.
Coarse grain ring control: meticulous metallurgical breakthrough
- Through stringent control of process parameters, we maintain the coarse grain ring thickness at ≤3mm.
- Utilizing computer simulation technology, we optimize extrusion and heat treatment parameters for each batch.
Straightness: precision in geometric assurance
- Utilizing advanced continuous extrusion technology, we ensure a high level of consistency throughout the forming process.
- Precision tension straightening equipment minimizes stress while optimizing straightness.
- A laser measurement system is used to monitor and adjust production parameters in real-time.
Post-Purchase processing recommendations for users
- Cutting Preparation: If sawing is required, please inform us in advance. We will reserve an additional 5mm margin for each cut.
- Heat Treatment Condition Selection: We primarily supply 2A11 T4 aluminum bars, which can undergo further heat treatment as needed.
- Weldability: Gas welding and argon arc welding are recommended. Perform heat treatment promptly after welding to restore material properties.
- Processing Complex Shapes: It is recommended to use CNC machining centers to ensure precision and consistency.
- Corrosion Resistance: After machining, surface treatments such as anodizing should be applied promptly.
Of course, we can also provide machining services such as turning, cutting, drilling, bending, sawing, and CNC processing.Quick Quote

2A11 corrosion-resistant packaging
- First, Chalco cleans the surface of the aluminum bars, removing processing oils and fingerprints.
- Each aluminum bar is separated and neatly arranged with pearl cotton.
- The bars are then wrapped with moisture-resistant kraft paper, followed by a thick moisture-proof film with desiccants inside.
- Finally, the package is secured with steel or fiber straps and packed in export fumigated wooden crates or pallets.
Custom packaging is also available upon customer request.
