According to the visual inspection, the silicon is ready. Magnesium? Copper? Aluminum composite nanoparticles, silicon? Magnesium? Copper? Sintering aluminum composite nanoparticles to remove impurities to obtain aluminum-coated Si-Mg-Cu cluster structure alloy powder. The alloy powder and aluminum powder with aluminum-coated Si-Mg-Cu cluster structure were mechanically ball-milled to prepare aluminum alloy powder with aluminum-coated Si-Mg-Cu cluster structure. Aluminum alloy cast bars were prepared by using aluminum alloy powder with Si-Mg-Cu cluster structure.

Aluminum alloy bar, aluminum-based alloy. The main alloying elements are copper, silicon, magnesium, zinc and manganese, and the secondary alloying elements are nickel, iron, titanium, chromium and lithium.
