Aluminum Tube Hydroforming: Formability and Mechanical Properties 2005-01-1392

Aluminum tube hydroforming offers further mass savings and performance improvement compared to solid stampings and castings. This paper reports the formability of 6063-T4 extruded tubes and 5754 seam-welded tubes. Tensile and fatigue properties of the hydroformed sections are investigated. The results also show that despite its lower yield strength (but higher ultimate tensile strength and ductility), the hydroformed 5754 alloy has higher fatigue resistance than the 6063-T7 material.
