Production method for Al-Zn-Mg-Cu series aluminum alloy panel for safety shoe box toes

The invention relates to the technical field of aluminum alloys, in particular to a production method for an Al-Zn-Mg-Cu series aluminum alloy panel for safety shoe box toes. According to the production method for the Al-Zn-Mg-Cu series aluminum alloy panel for the safety shoe box toes, chemical components including Si, Fe, Cu, Mn, Mg, Cr, Zn, Ti and the balance Al are adopted for casting an aluminum alloy casting ingot, the aluminum alloy casting ingot is subjected to the steps of preheating, hot rolling, cold rolling, cleaning and three-level annealing, and the aluminum alloy panel is manufactured. The obtained product has excellent and stable mechanical performance and meanwhile has high punching performance, high electric conductivity and good surface quality, and the punching using requirement for safety shoe toepiece materials can be met. 本发明涉及铝合金技术领域，尤其涉及种安全鞋内包头用Al-Zn-Mg-Cu系铝合金板材的生产方法。本发明所述的种安全鞋内包头用Al-Zn-Mg-Cu系铝合金板材的生产方法，是将化学成分Si、Fe、Cu、Mn、Mg、Cr、Zn、Ti、余量由Al熔铸铝合金铸锭，铝合金铸锭经预热、热轧、冷轧、清洗、三级退火步骤，制得到铝合金板材。本发明所得
