Title:
アルミニウム合金クラッド材及びその製造方法
Document Type and Number:
Japanese Patent JP7053281
Kind Code:
B2
Abstract:
An aluminum-alloy clad material includes a skin layer clad to and covering at least one surface of a core layer. The core layer is composed of an aluminum alloy containing Cu: 3.8-4.9 mass %, Mg: 1.2-1.8 mass % and Mn: 0.3-0.9 mass %. The core layer has an area number density of microvoids that have a circle-equivalent diameter of 0.5 μm or greater that is 100/mm2 or less. The skin layer has an Al purity of 99.5 mass % or greater. A method of manufacturing a wrought material from such an aluminum-alloy clad material includes heating the wrought material to the solution heat treatment temperature of the core layer at a temperature-rise rate of 50° C.-200° C./h.
