The Effect of Homogenization and Chemical Compositions of 6005 and 6082 Aluminium Alloys on The Cold Forming Process

Aluminium alloys are one of the most preferred materials in automotive industry due to their properties such as easy recyclability, formability and high specific strength. 6XXX especially used parts good mechanical corrosion fatigue strength.6XXX cast billets or ingots by continuous casting methods. The subjected homogenization heat treatment shaped extrusion, respectively. During extrusion forming, fibers formed profile direction extrusion. It has been observed that coarseness these process causes undesirable deep tears, cracks distortion surface when aluminium profiles cold forming process. In this study, cracking deformations completely eliminated occurred after thanks alloy improvements treatment. is modeled with finite element method order control forming. Alloy enhancement applied samples were As a result, part produced from improved chemical composition residual stresses invisible heterogeneities grain structure.
