FAQs
What are the processing methods for the 6063 aluminum flat bar produced by Chalco?
The manufacturing process of aluminum rows mainly includes two methods: extrusion and aluminum plate sawing.
Extrusion: This method involves feeding aluminum rods into a hot extrusion machine. By heating the rods, continuous extrusion of rectangular aluminum bars is performed. The bars are then straightened using a stretcher and cut to the required length after cooling.
Aluminum Plate Sawing: This process starts with aluminum alloy sheets. The method involves cutting, shaping adjustments, and surface treatments to create aluminum bars.
Each of these methods has its advantages, extrusion is suitable for large-scale production and complex cross-sections, while aluminum plate sawing is more suitable for small-scale production and customized dimensions.
What edge treatments can Chalco provide for 6063 aluminum Flat Bar?
Chalco can provide various edge treatments such as square edges, rounded edges, and R-rounded corners to meet the diverse requirements in different application fields.
