Abstract
An aluminum alloy material for forging obtained by a continuous casting process, the alloy comprising: a surface of which roughness is not more than Ra 35, and a segregation layer having 0.1 to 2 mm thickness and generated in the surface. The cast surface after continuous casting is smooth without peeling, a cast material can be forged without any treatment, and a segregation layer remains in a surface layer, thereby inhibiting coarsening of recrystallization grains and exhibiting superior toughness and strength.
