Aluminium Titanium master alloys are available in AlTi15, AlTi10, and AlTi5 grades, depending on the titanium content. They are widely used for titanium addition and grain refinement in aluminium alloys.

When added to molten aluminium, the master alloy produces a large number of TiAl₃ high-melting-point particles, which act as heterogeneous nucleation sites during solidification. This refines the grain structure, enhances uniformity, and significantly improves the strength, ductility, and overall mechanical performance of aluminium castings. With a low addition temperature and minimal titanium burning loss, AlTi master alloys are both efficient and cost-effective in refining applications.
