复合铝板
摘要：
一种复合铝板，它包括两块被固定在一块在其之间的波纹铝肋板的波峰和波谷上的平行板和/或薄板，其中波纹铝肋板是由一种具有这样的成分的铝合金轧制板材制成的(按重量百分比)：Mg 1.5-6.0；Mn 0.3-1.4；Zn 0.4-5.0；Fe不超过0.5；Si不超过0.5；Zr不超过0.30；和可能有的至少以下一种元素，Cr 0.05-0.30，Ti 0.01-0.20，V 0.05-0.25，Ag 0.05-0.40；Cu不超过0.40；其余杂质成分分别不超过0.05，总量不超过0.15；余量为Al；它在H条件下或在O条件下具有0.4-0.9的PS/UTS比并具有良好的轧制加工性能。
摘要（英）：

A composite aluminium panel comprising two parallel plates and/or sheets secured to the peaks and troughs of a corrugated aluminium stiffener sheet between the parallel plates and/or sheets, wherein the corrugated aluminium stiffener sheet is made from an aluminium alloy rolled sheet of composition (in weight percent): Mg 1.5-6.0, Mn 0.3-1.4, Zn 0.4-5.0, Fe up to 0.5, Si up to 0.5, Zr up to 0.30; optionally one or more of Cr 0.05-0.3, Ti 0.01-0.20, V 0.05-0.25, Ag 0.05-0.40, and Cu up to 0.40; and other elements up to 0.05 each, 0.15 total, with a balance of Al; and having in an H-condition or in an O-condition a ratio of PS/UTS in the range of 0.4 to 0.9 and having good roll formability.
