6063 aluminum flat bar

The non-uniform structure of 6063 aluminum flat bar is the main reason of bending orange peel and even cracking.Adjusting the alloy composition and extrusion process can effectively improve the inhomogeneity of the alloy structure and improve the bending performance.An extruded die structure with one - die and two - hole cover for semi - hollow aluminum profiles is presented.Through practical examples, the selection of the parameters of the die structure is introduced in detail.It mainly includes the selection of extruder capability, die hole layout, split hole design, lower die welding chamber structure and the selection of working belt.The checking method of die strength is introduced.The actual extrusion results of the traditional plane die, the single-hole diverging die and the new covered double-hole die are compared.
The us aluminium industry has invested heavily in building car production lines and boosting production of high-end aluminium.From 2013 to 2017, the investment in 6063 aluminum flat bar accounted for roughly 2.3 billion us dollars, adding 1,500 direct permanent jobs.In the period up to 2025, the automotive lightweight process in the United States is in a period of rapid and continuous rise, and the use of ABS will increase significantly.Proper increase of Mn and Cr content in 6082 alloy composition can effectively reduce the phenomenon of bending orange peel, and 6063 aluminum flat bar
 is adopted. The ingot heating temperature is 490 ° c ±5 ° c, the extrusion speed is 4.0m/min±0.5m/min, and the bending effect is better to meet customer requirements.The new mould has a simple structure and is easy to process.The practice shows that the new die structure can significantly improve the life of the die, improve the production efficiency and reduce the cost of aluminum profile.
