Abstract

The effects of Si

Ti elements content on the electrical conductivity of Al-Si-Mg alloy were investigated.The results indicate that with the content of Si increased from 6.0% to 7.5%

the conductivity is decreased from 20.8 MS/m to 19.2 MS/m.When the content of Mg is increased from0.16% to 0.45%

the electric conductivity of the alloy is decreased from 19.3 MS/m to 18.8 MS/m.When the grain refinement element Ti is changed between 0

.12%

the electric conductivity of the alloy is decreased from 20.5 MS/m to 19.2 MS/m.The experimental research on the heat treatment parameters show that the electrical conductivity and hardness are decreased with the increase of aging temperature and aging time.At 220 ℃for 6 h

the conductivity reaches 23.6 MS/m and the hardness is 76 HB

meeting the requirements of conductors for the alloy properties.
