PURPOSE:To provide a bracing sheet having high strength and excellent hanging resistance, the bracing sheet which is composed of an outer shell material made of an Al alloy contg. Si, and of a core material comprising essentrial components of Mn, Mg, and Si, and Zr and/or V. CONSTITUTION:An Al alloy bracing sheet is composed of an outer shell material made of Al alloy contg. Si, e.g., Al-10% Si alloy (AA4045 alloy) and of an Al alloy core material which comprises essential components, e.g., 0.6-1.5% Mn, 0.3-0.9% Mg, 0.3-1.6% Si; and one or both of 0.05-0.25% Zr, 0.01-0.1% V; or contg. one or both of 0.05-0.5% Cr, 0.05-0.35% Ti in addn. |
