铝复合片及其制造方法
摘要：
根据本公开的实施例，公开了一种铝复合片及其制造方法。一种可阳极氧化的铝复合片可包括：基体材料，其包括7xxx系列铝合金；以及涂覆材料，其包括设置在所述基体材料的前表面和后表面中的一者或两者上的6xxx系列铝合金或1xxx系列铝合金，其中，所述7xxx系列铝合金包含占所述铝复合片的总重量4.0％至8.0％的锌(Zn)、占所述铝复合片的总重量1.0％至3.0％的镁(Mg)，其余为铝(Al)和至少一种杂质。根据本公开的实施例，一种用于制造铝复合片的方法可通过在形成复合片之后采用热处理来增强复合片的粘合强度，并且可对复合片进行时效硬化而没有使强度劣化，由此实现了优异的表面和加工特性。
摘要（英）：

According to an embodiment, an aluminum clad sheet and method for manufacturing the same are disclosed. The anodizable aluminum clad sheet may comprise a base material including a 7xxx-series aluminumalloy and a coat material including a 6xxx-series aluminum alloy or a 1xxx-series aluminum alloy disposed on one or both front and back surfaces of the base material, wherein the 7xxx-series aluminumalloy includes 4.0% to 8.0% of zinc (Zn) relative to a total weight of the aluminum clad sheet, and 1.0 % to 3.0 % of magnesium (Mg) relative to the total weight of the aluminum clad sheet, and the rest being aluminum (Al) and at least one other impurity. According to an embodiment, a method for manufacturing the aluminum clad sheet may enhance the adhesion strength of the clad sheet by employingthermal treatment after forming the clad sheet and may age-harden the clad sheet without deteriorating strength, thereby achieving superior surface and processing properties.
