Aluminum alloy

Abstract

The present disclosure relates to aluminum alloy including about 1.4% by mass to about 1.6% by mass Mn; about 0.75% by mass to about 2.1% by mass Cu; about 0.4% by mass to about 0.7% by mass Fe; about 0.2% by mass to about 0.5% by mass Mg; about 0.1% by mass to about 0.2% by mass Ti; about 0.03% by mass to about 0.07% by mass Si; and the balance aluminum and incidental impurities. In the aluminum alloy, Al—Mg—Cu compounds are dispersed in a matrix.
