Aluminum Extrusion
The manufacturing process for 6061-T6 aluminum flat bars starts with aluminum extrusion. Manufacturers create a mold based on the desired cross-section. They heat a round aluminum cast bar and use an extruder to push it through the mold. Operators control temperature, pressure, and speed during this process to maintain product quality.
Stretching the Aluminum Flat Bar
After extrusion, the aluminum bars undergo stretching. They are placed in a stretching machine where tensile force is applied. This process deforms the bars at a specific temperature. As a result, the bars become thinner and their mechanical properties improve.
Surface Treatment
Once shaped, the aluminum flat bars receive surface treatment. Common methods include powder coating and anodizing. These treatments protect the surface from corrosion and damage from strong acids.
