Abstract：

Mill Finish (MF) and Electron Discharge Texture (EDT) commonly existing in the surface of aluminum body sheet (ABS) have a great influence on the properties of ABS, especially the stamping properties. The effects of surface topography on the surface properties and forming properties of 6016 ABS were systematically studied based on two kinds of ABS with MF and EDT surface topography and similar mechanical properties. The results show that the roughness of ABS with EDT surface is 2.5 to 4 times that of ABS with MF surface, ABS with EDT surface has higher forming limit FLD0 than the one with MF surface, and the friction properties, FLD0, bending and drawing properties of 6016 ABS with MF and EDT surface textures are similar.
