Abstract：
In high-voltage switch arc extinction products,some products need to improve their own conductivity,to reduce the circuit resistance.By controlling the Ti content in Al Sil0Mg alloy(≤0.03%),Sr modification and heat treatment aging(l90℃)were adopted to improve the morphology and distribution of Si phase,leading to the improvement of conductivity.On the premise of ensuring mechanical properties,the conductivity of the alloy is increased to more than 23.5 Ms/m to meet the requirements of electrical materials.
