Grain Refiners By Dhatukram

we are engaged in manufacturing, distributing, supplying and trading of Grain Refiners in Delhi, India. Grain refining is such a treatment of metal in a liquid state which leads to the formation of fine crystal grains and the improvement of mechanical properties of the casting.

Aluminium alloys freeze in large crystals which leads to lower the mechanical properties of the casting, retard feeding, cause shrinkage and contribute to leakage under pressure.In wrought aluminium products, coarse grain contributes to cracking.

Grain refining treatment produces a mass of minute crystals, eliminating these defects and results in-

Faster casting free of cracks
Reduces hot tearing
Reduced porosity
Improved surface finishing
Better feeding for casting alloys
Improved mechanical properties
Reduced rejection rate
