The 6xxx series aluminum alloys has attracted much attention owing to good strength,excellent formability and corrosion characteristics.The mechanical properties can be significantly improved by age-hardening.The effects of different aging system on the mechanical properties of 6082 aluminum alloy extru-sion bar were studied.The experimental results showed that the aging time could be shortened significantly by using higher aging temperature,and the yield strength could be reached or exceeded in a shorter time compared to the aging process of 175 ℃ ×8 h.Especially when the temperature exceed 195 ℃,the aging time could be shortened to 1 h,which not only reduced the energy consumption,but also improved the production efficiency.
