Effect of Si and Mn Addition on Fluidity, Mechanical Property and Casting Crack in Die Casting

Abstract:

The effects Si and Mn addition on the fluidity length, mechanical properties, and casting cracks of a die-cast Al-4.5%Mg alloy were investigated. The Si content was 1, 2, or 3 mass% and the Mn content was 0.3, 0.6, or 0.9 mass%. Both Si and Mn did not affect fluidity. Si content of more than 1 mass% improved casting crack resistance. The effect of Mn on casting cracks was weaker than that of Si. When Si content was 2 mass%, both tensile stress and elongation were good. Mn did not affect the mechanical properties.
