Research on Conductive Rail Technology of 6063 Aluminum Alloy with High Conductivity and Toughness

利用直读光谱、AXIO万能研究级倒置式材料显微镜、万能试验机、硬度测试仪及电导率测试仪,对6063合金成分、显微组织、力学性能、硬度及电导率进行检测分析,研究了不同合金成分配比、淬火冷却强度、时效处理对强度、硬度及导电率的影响。结果表明,适量的Si过剩有利于力学性能、硬度的提高,较低的过渡族元素含量可显著提高导电率;在保证强度、硬度的前提下,低冷却强度更有利于导电性能提高;185℃~195℃温度范围内时效,其综合性能最好。

Using direct reading spectrometry,AXIO universal research level upside-down materials microscope,universal testing machine,hardness tester,and electrical conductivity tester of 6063 alloy composition,microstructure,mechanical properties,hardness and electric conductivity detection analysis,this paper studies the different ratio of alloy composition,quenching cooling intensity,aging treatment effect on the strength,hardness and electrical conductivity.The results show that a moderate amount of excess Si is beneficial to the improvement of mechanical properties and hardness,and the lower content of transition elements can significantly improve the conductivity.On the premise of ensuring strength and hardness,low cooling strength is more conducive to improving conductivity;aging in the temperature of 185℃~195℃,its comprehensive performance is the best.
