本发明公开了一种耐腐蚀船舶装饰用铝合金带材及其制备工艺和应用,铝合金带材化学成分质量百分含量为:Si:0.50‑0.70%、Fe:0.65‑0.70%、Cu:0.18‑0.22%、Mn:1.40‑1.60%、Mg:0.002‑0.003%、Cr:0.008‑0.011%、Zn:0.0018‑0.0020%、Ti:0.028‑0.032%,其他单个杂质≤0.03%、总杂质合计≤0.15%,余量为Al,经熔铸、锯铣、均热、热轧、冷轧、拉弯矫直、退火、拉弯矫直加工而成,厚度为0.7~0.85mm。本发明制备的铝合金带材具有良好的耐腐蚀及力学性能,延伸率高,方便施工,且后工序制品板面细腻、折弯不易开裂、报废率低,能够适用于需要防腐蚀的海洋工程,船舶内部表面装饰,同时抵抗海风或海水的侵蚀。

    The invention discloses a corrosion-resistant aluminum alloy strip for ship decoration and a preparation process and application thereof. The aluminum alloy strip comprises the following chemical components in percentage by mass: 0.50 to 0.70 percent of Si, 0.65 to 0.70 percent of Fe, 0.18 to 0.22 percent of Cu, 1.40 to 1.60 percent of Mn, 0.002 to 0.003 percent of Mg, 0.008 to 0.011 percent of Cr, 0.0018 to 0.0020 percent of Zn, 0.028 to 0.032 percent of Ti, less than or equal to 0.03 percent of other single impurities, less than or equal to 0.15 percent of total impurities and the balance of Al. and the corrosion-resistant aluminum alloy strip is formed by casting, sawing and milling, soaking, hot rolling, cold rolling, stretch bending and straightening, annealing and stretch bending and straightening, and the thickness of the steel plate is 0.7-0.85 mm. The prepared aluminum alloy strip has good corrosion resistance and mechanical properties, is high in ductility and convenient to construct, and a product in a subsequent process is fine in plate surface, not prone to cracking after being bent and low in rejection rate, can be suitable for ocean engineering and ship interior surface decoration needing corrosion resistance and meanwhile resists corrosion of sea wind or seawater.
