Abstract
An aluminum alloy powder consists of Fe: 5.0 mass % to 9.0 mass %, V: 0.1 mass % to 3.0 mass %, Mo: 0.1 mass % to 3.0 mass %, Zr: 0.1 mass % to 2.0 mass %, Ti: 0.02 mass % to 2.0 mass %, and the balance being Al and inevitable impurities. The aluminum alloy powder contains an Al—Fe based intermetallic compound. An average circle equivalent diameter of the Al—Fe based intermetallic compound is in a range of 0.1 μm to 3.0 μm in a cross-sectional structure of the aluminum alloy powder. An aluminum alloy extruded material excellent in mechanical properties at high temperature is provided.
