The effect of Si addition on the microstructure and mechanical properties of Al-Mg-Si-Zn aluminum alloys were investigated. Results show that the microstructure of Al-Mg-Si-Zn alloy with low Si contents is mainly composed of Mg2Si and Mg5Si6 phases. With the increasing of Si content. Si and Al3. https://parisnaturalfoodes.shop/product-category/org-ground-cinnamon/
