Title:
MANUFACTURING METHOD OF Al-Mg-Si-BASED ALLOY SHEET
Document Type and Number:
Japanese Patent JP2017179451
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of an Al-Mg-Si-based alloy sheet having high strength while having high conductivity and good processability.SOLUTION: In a manufacturing method of an alloy sheet in which hot rolling and cold rolling is conducted in sequence on an ingot containing Si: 0.2 to 0.8 mass%, Mg: 0.3 to 1 mass%, Fe: 0.5 mass% or less and Cu: 0.5 mass% or less and further at least one of Ti: 0.1 mass% or less or B: 0.1 mass% or less and the balance Al with inevitable impurities, the surface temperature of the Al-Mg-Si-based alloy sheet is set at 170°C or less just after completion of the hot rolling and heat treatment at a temperature of 120°C or more and less than 200°C is conducted after completion of the hot rolling and before completion of the cold rolling.SELECTED DRAWING: None
