1. the aluminium alloy plate manufactured by the ingot bar utilizing DC casting to cast, is characterized in that:

  • The Cr of the Mg containing 2.0 ~ 3.0 quality %, 0.15 ~ 0.25 quality %, the Ti of the Ti of 0.005 ~ 0.20 quality % or 0.005 ~ 0.20 quality % and the B of 0.0005 ~ 0.05 quality %, rest part is Al and inevitable impurity, the Si in this impurity is made to be below 0.15 quality %, Fe is below 0.4 quality %, Mn is below 0.06 quality %, if the content of described Cr is T cRthe solid solution capacity of quality %, Cr is S cRduring quality %, T cR-S cRvalue P cRmeet P cR

    0.065 quality %, P cRthe amount of the Cr in intermetallic compound, Even if this aluminium alloy plate carries out the anodic oxidation treatment utilizing sulfuric acid bath, also can do one'"'"'s utmost to suppress to send yellow color, and send the color of not reddish pale green white color system.
