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.
ALEASTUR produces the widest range of high quality aluminium grain refiners in the market, suitable for all of aluminium wrought and foundry alloys production and their multiple applications, from transportation and food and beverage to energy and construction.
AlTiB alloys (Aluminium Titanium Boron alloys) are the most common used aluminium grain refiners in aluminium alloys manufacturing. Available in different Titanium/boron ratios, selection of ratio between Titanium and Boron will depend on several factors as desired grain size, production process conditions and percentage of recycled aluminium used in the alloy.
AlTiC alloys (Aluminium Titanium Carbon alloys), salts based or metal based are the best alternative for those aluminium alloys where the addition of boron might be counterproductive as for some 5000 and 7000 series alloys and EC grade aluminium.
006 UltimateTM is the latest development in grain refiners, especially designed to achieve the highest cleanliness in aluminium alloys without compromising grain refining efficiency.
SupremeTM is ALEASTUR’s High Efficiency Grain Refiner. Strongest grain refiner efficiency at low addition rates along with metallographic excellence make SupremeTM the best choice among high performance aluminium grain refiners.
