The mechanica l properties of import corbel on some parts with different thickness and the effects of low temperature on the mechanical property were obtained by sectioning analysis on import aluminum alloy corbel. Based on the tested results on the import corbel, the effects of heat treatment process on the properties of aluminum alloy corbel were investigated. The results show that the T6 heat treatment process of the corbel can slightly obtain high strength and similar plasticity, when compared with impo...
