Description

technical field [0001] The invention relates to an automobile wheel hub, in particular to a method for preparing a high-temperature-resistant aluminum alloy automobile wheel hub. Background technique [0002] Common car wheels include steel wheels and aluminum alloy wheels. Aluminum alloy wheels have the following advantages: beautiful and generous; light and fuel-efficient; high expansion rate, good elasticity; good thermal conductivity; good roundness, not easy to deform, suitable for high-speed driving; Absorbs vibration and noise during movement. However, aluminum alloy wheels have poor heat resistance, and if the wheels are always in a high temperature state, the service life of the wheels will be damaged. Therefore need to study a kind of preparation method of high temperature resistant aluminum alloy automobile hub. Contents of the invention [0003] The object of the present invention is to provide a method for preparing a high-temperature-resistant aluminum all...
