Title:
METHOD FOR MANUFACTURING ALUMINUM ALLOY FOR HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2022/231148
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing an aluminum alloy for a heat exchanger. The present invention pertains to a heat treatment process method for simultaneously achieving excellent perforation corrosion resistance and mechanical properties in an aluminum alloy material used in a heat exchanger. More specifically, proposed are: conditions for homogenization heat treatment which is divided into two stages, that is, a high-temperature stage and a low-temperature stage, and is for the uniform formation of fine precipitated phases; and conditions for annealing heat treatment for obtaining excellent tensile strength and elongation.
