In the process of aluminum casting, controlling grain size plays a key role in maintaining the stability and high quality of products and controlling the cost while maintaining high yield.Adding an appropriate amount of aluminum-titanium-boron grain refiner into the aluminum solution can release nucleation particles in the process of casting aluminum alloy, form fine grains of equiaxial axis, prevent the formation of columnar crystallization, and improve the casting speed.

Adding aluminum, titanium and boron grain refiner can improve the uniformity, make the alloy elements evenly distributed, reduce the porosity, avoid hot cracking, improve the heat treatment performance, strengthen the mechanical properties and mechanical properties in the manufacturing process.

Continuous addition of aluminum titanium boron wire is a very effective way to treat various aluminum alloys.

There are two kinds of particles in the microstructure of al ti b grain refiner: TiB2 particles and TiAl3 particles.TiB2 particles are crystalline cores, usually 1-2 microns in size and insoluble in aluminum solution.TiAl3 particles are larger than TiB2 particles, usually 30-50 microns in size, and are completely dissolved in an aluminum solution.Both particles play an important role in grain refinement.

After decades of research and improvement on aluminum alloy grain refiner, aluminum titanium and boron have become the first choice of aluminum casting industry in the world.
