Aluminum Strontium Coil differs from other modifiers in that it retains its modification effectiveness for extended periods of melt holding time. Modification of the morphology of the silicon phase in aluminium silicon alloy castings from coarse platelets to a fine fibrous eutectic structure results in improved soundness and mechanical properties.

Binary aluminum–silicon alloys, however, have relatively low strengths. Hence, other elements such as copper and magnesium are added to obtain higher strengths through heat treatment. A small amount of sodium or strontium is frequently added to modify the aluminum–silicon eutectic to give increased ductility.
