titanium boron aluminum grain refiner (Al-Ti-B)

The addition of a 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.

Application and characteristics of AlTiB

AlTiB aluminum titanium boron grain refiner, additive when melting, simple to use and no corrosive effect, little application amount, high purity, great grain refining effect, improvement surface quality, reduction pinhole number and raising elongation. A necessary modification material used in producing the aluminum alloy wheel hub of automobile and motorcycle and aluminum plate,sheet,foil and the high performance aluminum casting of aeronautical and astronautical,military enterprises.

Instructions on application of Al-Ti-B

Adding temperature:680-720°CApplication amount:determinated by actual experiments and dosing calculationAdding method:in-line adding
