Abstract：
Inhighvoltageswitcharcingproducts, it isnecessarytoreduce the loopresistancebyimprovesomeproducts
conductivity.BycontrollingtheTicontent inAlSi10Mgalloy (≤0.03%)andadoptingSrmodificationandheat treatment
aging (190℃), themicrostructureanddistributionof theSiphasewere improved, leadingtoasignificant increase inits
electrical conductivity.The results showthat theelectrical conductivityof theAlSi10Mgalloycanbe increased tomore
than23.5ms/mtomeet therequirementsofelectricalmaterialsonthepremiseofguaranteeingitsmechanicalproperties.
