It is effective in decreasing the grain size by modification of the microstructure of aluminum and aluminum alloys.

High melting point particles formed by AITİ5B, such as TİB₂, TİAI₃ and AIB₂ dissolve into the matrix homogenously and improves mechanical, electronic and machining properties of the alloy. It improves the surface quality and brightness of the final product, thus decreases the quantity of defected products.
