본 발명의 일 측면에 따른 알루미늄 합금판은, 포정원소 및 Mg를 함유한다. 상기 알루미늄 합금판의 판두께를 t(mm), t/2 부분을 기준으로 하여 ±0.01×t(mm)의 범위를 판두께 중앙부, t/4 부분을 기준으로 하여 ±0.01×t(mm)의 범위를 판두께 1/4부, 최표층 부분으로부터 판두께 방향으로 0.02×t(mm)까지의 범위를 판두께 표층부로 한 경우, 상기 포정원소의 농도에 대하여, 상기 판두께 중앙부와 상기 판두께 1/4부의 농도의 차이 및 상기 판두께 중앙부와 상기 판두께 표층부의 농도의 차이가 0.04%(질량%, 이하 동일) 이하이다. 또한, 상기 Mg의 농도에 있어서, 상기 판두께 중앙부와 상기 판두께 1/4부의 농도의 차이 및 상기 판두께 중앙부와 상기 판두께 표층부의 농도의 차이가 0.4% 이하이다.
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.
