Abstract
PURPOSE: To manufacture an Al alloy sheet suitable for working with transfer dies by subjecting a cold rolled sheet of an Al-Fe-Si-Cu alloy having a specified composition to recrystallization annealing.
CONSTITUTION: An Al alloy having a composition contg. 0.05W0.25% Si, 0.3W 0.7% Fe and 0.01W0.2% Cu in ≥3.5 ratio of Fe/Si is melted and cast. This ingot is soaked and formed into a plate having ≥2.5mm thickness by finish hot rolling at 200W310°C, and after reducing the thickness to 0.2W0.5mm by finish cold rolling, the resulting sheet is subjected to recrystallization annealing at 350W 360°C for 2W3 hr. Thus, an Al alloy sheet giving a blank pressed by transfer die working without breaking or curving a skeleton remaining in the sheet is obtd.
