Abstract (en)
[origin: EP0818553A1] In a method for the manufacture of aluminium alloy sheet having a content of Mg of 1.5 to 8.0 wt% and a total content of (Mn + Cr + Zr) of not more than 0.1 wt%, a solution heat treatment step is carried out at final thickness of the sheet in a continuous annealing furnace. In this solution heat treatment the heating rate of the sheet in the heating region of said continuous annealing furnace is at least 50 DEG C/s. Induction heating may be used. Improved properties can be obtained.
