Title:

HIGH-STRENGTH ALUMINUM ALLOY PLATE HAVING EXCELLENT PAINT BAKE HARDENABILITY, AND MANUFACTURING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2017/179794

Kind Code:

A1

Abstract:

The present invention relates to a high-strength aluminum alloy plate having excellent paint bake hardenability, and a manufacturing method therefor, and by performing a preliminary aging treatment for 3-250 minutes at a temperature of 65-145°C after solution heat treatment during the manufacture of a plate, a physical property change due to natural aging during transport and storage of the plate is suppressed, and the strength of the plate can be further improved by paint bake-hardening after chassis molding and painting, thereby having an advantage of enabling a high-strength lightweight transport vehicle chassis to be manufactured.
