Development of novel Al-Si-Mg alloys with 8 to 17 Wt% Si and 2 to 4 Wt% Mg

A new family of Al alloys is being developed to obtain superior castability and properties of the cast component as compared to conventional Al-Si cast alloys. Alloys with compositional ranges varying from 8 wt% to 17 wt% Si coupled with 2 wt% to 4 wt% Mg are being investigated. These alloys were developed based on our understanding of the effect of various iron containing phases and Sr additions on the nucleation of the eutectic phases in …
