Controlling Your Aluminum Melt

September 2006
Modern Casting;Sep2006, Vol. 96 Issue 9, p48
The article offers a guide to controlling aluminum melt. During the process of solidification, aluminum grains grow into dendrites with multiple arms, like the branches of a tree. Grain refining adds nucleating sites into the melt to initiate grain growth. The primary method of silicon modification is the addition of strontium master alloy.
