摘要
Improved aluminum master alloys containing strontium and boron are provided for simultaneously modifying and grain refining Al alloys, and in particular, hypoeutectic Al-Si alloys. The improved master alloy contains, by weight percent, about 0.20-20% Sr, 0.10-10% B, and the balance Al with impurities. The master alloy may also contain about 0.20 to about 20% Si by weight percent. The master alloys have a high degree of ductility for purposes of forming continuously rolled master alloy rod stock.
