A vehicle compressor component includes an aluminum alloy material made by hot-extruding. The aluminum alloy material has a chemical composition consisting of Fe: 5.0% to 9.0% by mass, Mg: 0.7% to 3.0% by mass, V: 0.1% to 3.0% by mass, Mo: 0.1% to 3.0% by mass, Zr: 0.1% to 2.0% by mass, Ti: 0.02% to 2.0% by mass, and balance Al and unavoidable impurities. The aluminum alloy material has a density of 2.96 g/cmor more. A method for manufacturing the vehicle compressor component includes: compacting aluminum alloy powders having the chemical composition to prepare a compact; hot-extruding the compact to make an aluminum alloy material; and forming the aluminum alloy material into a desired shape.
