In-Depth Analysis: Effect of Normal Quenching and Delayed Quenching on the Properties of 6061 Aluminum Alloy

Large wall thickness 6061T6 aluminum alloy needs to be quenched after hot extrusion. Due to the limitation of discontinuous extrusion, a part of the profile will enter the water-cooling zone with a delay. When the next short ingot is continued to be extruded, this part of the profile will underg...
