Document Type and Number:
WIPO Patent Application WO/2023/246736
Kind Code:
A1
Abstract:
Disclosed is a method for manufacturing an Al-Zn-Mg-Cu series aluminum alloy plate. The method comprises: (1) preparing an Al-Zn-Mg-Cu series aluminum alloy ingot; (2) sequentially performing homogenization, hot rolling, cold rolling, solid solution quenching and artificial aging on the Al-Zn-Mg-Cu series aluminum alloy ingot to obtain a T6-state aluminum alloy plate; (3) performing heating, warm forming, in-mold quenching, pre-aging and paint baking treatment on the T6-state aluminum alloy plate to obtain a finished aluminum alloy plate. Further disclosed is an Al-Zn-Mg-Cu series aluminum alloy plate, made using the above manufacturing method. The present invention standardizes the production process and process parameters of the Al-Zn-Mg-Cu series aluminum alloy plate, and the Al-Zn-Mg-Cu series aluminum alloy plate prepared by said manufacturing method has high tensile strength, yield strength and elongation, can be applied to automobiles, and has good popularization prospects and application value.
