DATASHEETAluminium Titanium Boron(AlTi5B1)
Usage
The addition of titanium boron aluminum grain refiner improves homogeneity and allows for
a uniform distribution of alloying elements,reduces porosity,eliminates hot tearing in cast
structures,improves responsiveness to subsequent heat treatment,and enhances
mechanical properties and machinability in the fabrication process.Continuous injection of
titanium boron aluminum rod is a highly effective treatment for all aluminum alloys.
