The addition of grain refiners on cast metal is the most effective way of developing a thin, uniform granular structure through the addition of nucleating agents.

Grain refiners with different relationships between titanium and boron or between titanium and carbon are available for use in the different features of each process. The selection of the most suitable grain refiner for use should consider the type of allow to be treated, the amount of remelting or secondary aluminum used in the process, the size of the final grain, as well as the melting and leakage practices (solidification rate) of each process.

Technical information in a data sheet, as well as the expertise of the engineers and the technical staff of AMG Brazil are available for helping our clients to define the most appropriate grain refiner and a great rate of addition for each process.
