A PROCESS OF PREPARING AN ALCLAD ALLOY SHEET

摘要

The present invention relates to a process of preparing an Alclad alloy sheet of thickness 2 to 4 mm. AA2219 (Al-Cu-Mn-Ti-V-Zr) based alloy slab welded with the cladding alloy AA7072 (Al-Zn) plate is heated at 515 ± 5 °C for 20-24 h followed by hot rolling, cold rolling and heat treating to T83 temper comprising of solution treatment, quenching, cold working and artificial aging to attain the peak strength.
