Melt Treatment - Grain Refining & Modification

The need for smaller grains is vital to achieving the required properties when pouring most cast aluminum alloys. Whether the desired results are high mechanical properties, leaker free castings, a cosmetic appearance or improved structural soundness, smaller grains are impactfully beneficial. 

 • In -situ formation of nuclei, such as TiB2, in the melt

 • In-situ nuclei are very active, effective and well distributed throughout the melt

 • Fine grain structure improves the solidified structure and reduces shrinkage porosity

 • Grain refining improves mechanical properties of the casting, such as elongation
