Al. Ti. B. Alloys
In casting applications, the control of grain size is absolutely essential in maintaining product consistency and quality, in reducing costs and maintaining high levels of productivity. The controlled addition of BALAJI ALUMINIUM-TITANIUM-BORON grain refiner to molten aluminium releases nucleant particles that promote equiaxed, fine grain structures throughout the cast alloys, thus avoiding formation of columnar crystals. Casting speed can be increased, and improved feeding characteristics achieved.
ATB BENEFITS
Smoke free, toxic gas free working atmosphere.
Fast acting: two minutes residence time.
Ideal for long holding times and ingot remelting.
Highly efficient grain refining.
Improved mould filling.
Improved distribution of porosity gives less scrap after machining.
Fewer shrinkage defects.
Reduced reject levels on x-ray inspection.
Recovery ensured 96% to 98% positively.
There is a wide range of BALAJI ALUMINIUM –TITANIUM- BORON ALLOY available to suit customer’s requirement and casting methods.

Product Forms and Packaging
For continuous injection into the metal stream, ATB grain refiners are available as coiled rod. For ease of handling and accurate, continuous addition, de-coilers and reliable automatic rod feeders are also available on order.
For furnace additions, ATB as waffle plate/cup form is added as the melt treatment is completed, usually within 20 minutes prior to casting.
Recommended Quantity to be used
It is always depending upon the degree of grain refinements required time to time as per the foundry practises however, we recommend 0.1% to 0.15 Max to be used to obtain the optimum results.
