In order to fabricate the aluminum alloys with good drawability, the textures evolution of the AA5182 sheets after rolling and annealing was studied. The measurement of the deformation textures was carried out for the sheets which were cold rolled with high reduction ratio by using the symmetric roll. In addition, the change of the recrystallization texture was investigated after heat-treatments of the rolled sheets with various heat treatment conditions. Rolling without lubrication and subsequent annealing led to the formation of favorable $rot-C_{ND};{001}<110>;and;{gamma}-fiber ND//<111>$ textures in AA5182 sheets. From the results, the ${gamma}$-fiber ND//<111> component well evolved during rolling at highest reduction ratio (over $90\%$, l/d parameter of 6.77). Among shear deformation textures, the ${gamma}$-fiber ND//<111> was not rotated in holding time of $180~7,200$ seconds at $350^{circ}C$. The Monte-Carlo technique was used and could be representatively simulated these textures evolution during recrystallization.
