The effect of silicon composition on corrosion behavior of aluminum die-cast

ADC 12, ADC 1 and HT 1 die cast aluminums mainly differ in their composition of silicon. The shape of silicon particles had made a difference in term of improving strength, elasticity, corrosion resistance and promotes large grain sizes which causes increasing magnetic permeability, and presumably c...
