Super Uniformity in Mechanical properties of Automotive Structural Members

摘要

The practical application to automobiles has been the most important target for Aluminum extrusion shapes. For examples, the space frame is produced through the bending process after the artificial aging for 6000-series alloy extruded shapes. The precision in the size of the materials after bending requires the uniformity of the 0.2/100 proof stress for Al-Mg-Si alloys, for instance, the tolerance level of the proof stress for 6063-T5 is not beyond ±15MPa.
