Casthouse Grain Refining

In casthouse applications, the control of grain size is absolutely essential in maintaining product consistency and quality, in reducing costs and maintaining high levels of productivity.

The controlled addition of AMG Aluminum’s titanium boron aluminium TiBAl™ grain refiners to molten aluminium releases nucleant particles that promote equiaxed, fine grain structure throughout the cast alloy, thus avoiding formation of columnar crystals. Casting speed can also be increased, and improved characteristics achieved.
