Grain Refiners for Al-Si Hypo-Eutectic and Eutectic .
CERALOY-TiB is recommended to overcome many of the above problems. Being metallic in nature, CERALOY-TiB dissolves readily in aluminium alloys and thus gives more consistent results as compared to salt-based grain refiners. It has superior fade resistance and hence retains the refinement effect over a much longer period of time.
