Close control of the cast structure is a major requirement of high quality aluminium alloy products. The most effective way to provide a fine and uniform as-cast grain structure is to add nucleating agents which are commonly referred to as Grain Refiners to aluminium to control crystal formation during solidification.

Available products are in form of rod coil and cut rod.
Application: To improve homogeneity and allow for a uniform distribution of alloying elements, reduce porosity and eliminate hot tearing in cast structures, improve responsiveness to subsequent heat treatment, and enhance mechanical properties and machinability in the fabrication process.
