PURPOSE: An aluminium alloy plate with superior moldability is provided, which can be applied to a vehicle body panel by preventing random marks and SS marks. CONSTITUTION: An aluminium alloy plate with superior moldability comprises one or more selected among Mg 0.5~7.0 weight%, Zn 1.0~4.0 weight%, Fe 1.0 weight% or less, Mn 1.0 weight% or less, Cr 0.3 weight% or less, Zr 0.3 weight% or less, V 0.3 weight% or less, Ti 0.1 weight% or less, and Cu 1.0 weight% or less, and the rest Al and inevitable impurities. A pre-machining is performed on the aluminium alloy plate in order to prevent parallel band caused by serration in a stress-strain curve or random marks. |
