Abstract: 
PROBLEM TO BE SOLVED: To provide an Al alloy material for high speed motion parts, having high high-temperature characteristics and excellent in machinability. SOLUTION: The Al alloy forging material is composed of an aluminum alloy having a composition consisting of 1.5-7.0% Cu, 0.01-2.0% Mg, and the balance aluminum with inevitable impurities. Further, the microstructure after solution heat treatment has θ'-phases and/or Ω-phases and is composed of equiaxed recrystallized grains 1 of ≤500 μm grain size, and 1000 hr creep rupture strength and high temperature proof stress are regulated to ≥250 N/mm2 and ≥280 N/mm2, respectively.
