Abstract：
With the improvement of automobile lightweight and service conditions on the performance of automobile parts,the casting production technology always used in automobile wheel hub production has its technical limit to improve the performance of the wheel hub.Recently,the near-net forming technology has become the key technology to improve the performance of aluminum alloy wheel hub.Semi-solid forming technology,powder metallurgy forming technology,spinning forming technology,extrusion forming technology have been applied in the production and forming of aluminum alloy hub.The basic process flow of this kind of technology in the forming of wheel hub is summarized,in order to have a certain reference value in the production process of near-net forming aluminum alloy.
