Abstract

PURPOSE:To obtain the aluminum alloy sheet for vessels excellent in a drawing formability and brightness by forming the recessed or projecting part in limited diameter and depth at limited mean center intervals on the surface of the aluminum alloy sheet. CONSTITUTION:The diameter of a recessed or projecting part arranged on the surface is taken in 1-2000mum. In the case of the diameter being less than 1mum the stagnant effect of a lubrication oil is nil and it does not contribute to the improvement in drawing formability. When the diameter exceeds 2000mum, the lubrication oil is made difficult to be held on the surface to impede the formability. The depth in the recess or the height of the projecting part is taken in 0.1-200mum. In the case of less than 0.1mum the holding effect of the lubrication oil is eliminated and it does not contribute to the improvement in the drawing formability. In the case of exceeding 200mum the brightness is hampered. The mean center gap of the mutual recess or project parts is taken in 5-5000mum. In the case of less than 5mum the brightness is hampered and when exceeding 5000mum, the lubrication effect is reduced to impede the drawing formability.
