Document Type and Number:
Japanese Patent JP5678213
Kind Code:
B2
Abstract:
An aluminum alloy plate according to one of the aspects of the present invention comprises peritectic elements and Mg. Wherein plate thickness of the aluminum alloy plate is represented as t (mm), a range within ±0.01×t (mm) from t/2 is represented as a central portion, a range within ±0.01×t (mm) from t/4 is represented as a quarter portion, and a range within 0.02×t (mm) from a top surface in the plate thickness direction is represented as a superficial portion, concentration of the peritectic elements is such that a concentration difference between in the central portion and in the quarter portion, and a concentration difference between in the central portion and in the superficial portion are 0.04% (mass %, same applies hereinafter) or less. In addition, concentration of the Mg is such that a concentration difference between in the central portion and in the quarter portion, and a concentration difference between in the central portion and in the superficial portion of the plate thickness are 0.4% or less.
