Process optimization of Cu-Al contact wire based on numerical simulation

SHEN Xiao-xiao1,LI Jing-yuan1,YANG Bin2,XIE Jian-xin1(1.School of Materials Science and Engineering,University of Science and Technology Beijing,Beijing 100083,China;2.Faculty of Material and Chemical Engineering,Jiangxi University of Science and Technology,Ganzhou 341000,China)  
Drawing process of Cu-Al contact wire was investigated by DEFORM-3D.The distributions of stress/strain/velocity field were obtained.Apertures defect and bending phenomena were analyzed.By varying copper wire geometries,a better bonding was get.To keep contact wire straight,the Al sizing belt length should be adjust to 2 mm and Cu sizing belt length to 5 mm.The influence of the angles of drawing die was also analyzed.
