Taking 6106 aluminum alloy automotive energy-absorption profiles as the research object,the effects of different aging systems on the mechanical properties,conductivity and crushing performance of 6106 aluminum alloy profiles were studied.The results showed that the strength of alloy increased first and then decreased with the prolongation of aging time.The higher the aging temperature,the shorter the time required for the alloy to reach the peak strength,and the peak strength decreased with the increase of aging temperature,so the alloy had the highest strength at 175 ℃.The electrical conductivity of the alloy in-creased with the increase of aging temperature and time,and the growth rate of the electrical conductivity in the underaging stage was greater than that in the over-aging stage,and the"watershed"of the growth rate corresponded to the peak aging time.Under the aging system of 203℃ × 3.5 h and 203℃ × 4.5 h,the ex-trusion energy-absorption effect was the best,and the magnitude of energy-absorption was proportional to the strength.
