    • An aluminum sheet material for automobiles is herein disclosed, having an aluminum alloy composition: (i) comprising 3.5 to 5 wt % of Si, 0.3 to 1.5 wt % of Mg, 0.4 to 1.5 wt % of Zn, 0.4 to 1.5 wt % of Cu, 0.4 to 1.5 wt % of Fe, and 0.6 to 1 wt % of Mn, and one or more members selected from the group of 0.01 to 0.2 wt % of Cr, 0.01 to 0.2 wt % of Ti, 0.01 to 0.2 wt % of Zr, and 0.01 to 0.2 wt % of V, with the balance of aluminum and unavoidable impurities, or (ii) comprising between more than 2.6 wt % and 5 wt % of Si, 0.2 to 1.0 wt % of Mg, 0.2 to 1.5 wt % of Zn, 0.2 to 1.5 wt % of Cu, 0.2 to 1.5 wt % of Fe, and between 0.05 and less than 0.6 wt % of Mn, and one or more members selected from the group of 0.01 to 0.2 wt % of Cr, 0.01 to 0.2 wt % of Ti, 0.01 to 0.2 wt % of Zr, and 0.01 to 0.2 wt % of V, with the balance of aluminum and unavoidable impurities. It is possible to produce an aluminum sheet material for automobiles that has excellent mechanical strength and bending property as well as enhanced weldability, by making the recycling use of recycled aluminum materials.
    • 本文公开了一种汽车用铝板材,其具有铝合金组成:(i)包含3.5〜5重量%的Si,0.3〜1.5重量%的Mg,0.4〜1.5重量%的Zn,0.4〜1.5重量%的Zn, Cu,0.4〜1.5重量%的Fe和0.6〜1重量%的Mn,以及选自0.01〜0.2重量%的Cr,0.01〜0.2重量%的Ti,0.01〜0.2重量% 的Zr和0.01〜0.2重量%的V,其余为铝和不可避免的杂质,或(ii)包含大于2.6重量%至5重量%的Si,0.2-1.0重量%的Mg,0.2至1.5 Zn的重量%,Cu的0.2〜1.5重量%,Fe的0.2〜1.5重量%,Mn的0.05〜0.6重量%,以及选自0.01〜0.2重量%的Cr的一种或多种 ,Ti:0.01〜0.2重量%,Zr:0.01〜0.2重量%,V:0.01〜0.2重量%,余量由铝和不可避免的杂质构成。 可以通过再循环使用再生铝材料来生产具有优异的机械强度和弯曲性以及增强的可焊性的汽车用铝板材。
