Identification of Surface Defects on Aluminum Profiles

We have tried to collect detailed information regarding surface defects in aluminum extrusions. These are extruded profiles made of soft and medium strength aluminum alloys such as 6060, 6063, 6005A, 6061 and 6082. High strength aluminum alloy profiles (e.g., 2xxx, 5xxx and 7xxx series alloys) ma...
