摘要：

PROBLEM TO BE SOLVED: To provide a Cu-Al-Mn based alloy material excellent in breaking extension and a seismic control member using it.SOLUTION: Provided is the Cu-Al-Mn based alloy material having 50% or more of crystal grains in area fraction in an observation area, in which a ratio of average crystal grain length (long side) in a direction parallel to a stress axis and average crystal grain length (short side) in a direction vertical to the stress axis observed in the observation surface in the direction parallel to the stress axis, namely a ratio of short side/long side, is 0
