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

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.
