Strontium Aluminum Alloy SrAl 90/10 was used to hypoeutectic Aluminum-Silicon casting alloy to obtain a modifying effect, replace aluminum strontium master alloy with lower strontium content , such as alsr5, als10 and alsr15 etc., by changing the structure of eutectic silicon, the morphology of silicon changes from rom acicular lamellar to uniform and globular, so as to achieve the modifying effect. Lower melting point 580 °C and save cost.
