Aluminium Titanium Boron (AlTiB) Master Alloy
Aluminium Titanium Boron (AlTiB) master alloy is a highly effective grain refiner for aluminium alloys, enhancing strength, plasticity, and casting quality through uniform grain refinement.
The Aluminium Titanium Boron (AlTiB) Master Alloy is widely recognised as one of the most effective grain refiners for aluminium and aluminium alloys. By preventing the formation of coarse equiaxed, columnar, and feathered crystals, it significantly enhances the mechanical strength, plasticity, and overall physical properties of aluminium castings.
The refining mechanism is closely linked to the presence of TiAl₃ and TiB₂ particles. Smaller and more active nuclei improve grain refinement, prevent agglomeration, and ensure uniform distribution. When introduced into molten aluminium, AlTiB releases a large number of heterogeneous nucleation cores, which influence crystallisation during solidification and result in finer, more uniform alloy grains.
