Abstract (en)
An aluminum alloy material has a composition containing 3% by mass or more and 10% by mass or less of Fe and the balance of A1 and incidental impurities, and a structure including a matrix and a compound. The matrix is composed mainly of Al, the compound contains Al and Fe, and a relative density is 85% or more. In any cross section, the matrix has an average crystal grain size of 1,100 nm or less, and the compound has an average major-axis length of 100 nm or less.
