5th step: be 8～12 ms/min in crystallizing wheel rotational line speed, under conditions of finish to gauge speed is 7～9 meter per seconds, aluminum alloy melt continuous casting and rolling become the Aluminum alloy round bar of a diameter of 9.5 millimeters；
6th step: passage drawing deformation amount be 6～7%, under conditions of drawing speed is 7～9 meter per seconds, Aluminum alloy round bar is drawn into the aluminium alloy wire of a diameter of 2～4 millimeters；
7th step: by aluminium alloy wire 130～150 DEG C of Ageing Treatment 12～16 hours, obtain rare-earth aluminum alloy lead wire after furnace cooling.
