Grain refining is a key factor in melting and solidification processes of aluminium alloys. Addition of grain refiners to molten aluminium alloys reduces aluminium grain size, improves fluidity allowing faster casting speeds, enables a better homogeneity and uniformity of the structure of the alloy, reduces cracking tendency during solidification, enhances mechanical properties of the alloy and improves quality surface of final product.

Addition of alloying elements to aluminium can be made in various formats. Master alloys ease a quick dissolution of alloying elements in liquid aluminium with a high efficiency.

Potassium aluminium fluoride is an inorganic salt, a byproduct obtained as a result of grain refiners and master alloys production process.

This product is commonly used as a substitute of fluoride salts in many different industrial applications.
