A heat-resistant wrought aluminum alloy is characterized by containing the following metal elements: silicon 0.05-0.10%, iron 0.8-1.5%, copper 1.5-3.0%, manganese 0.2-0.5%, magnesium 1-2%, nickel 1-2% %, zinc 0.1-0.5%, titanium 0.05-0.15%, molybdenum 0.01-1% and the balance aluminum. The alloy obtained by the invention is a heat-resistant wrought aluminum alloy with less silicon content and high thermal strength; after adding titanium element, the structure is fine; after adding silicon, molybdenum, nickel, copper, iron and other elements, it can form thermal stability with aluminum The better excess phases Al2CuMg, Al6Cu3Ni, Al2FeSi, Al3Ti, Al2Cu4Mg5Si4, etc., improve the thermal strength of the aluminum alloy, can be strengthened by heat treatment, and have high plasticity in the hot state; do not contain manganese, chromium, so there is no extrusion effect, resistance Good welding, spot welding and seam welding performance, good corrosion resistance and machinability. It can be used to manufacture pistons of internal combustion engines and complex forgings that work at high temperatures, such as compressor impellers, blower impellers, etc.
