  • Grain Refiners

General Description

CERALOY-B is aluminium-boron master alloy recommended for grain refining aluminium alloys.


  • Boron is used in aluminium and its alloys as a grain refiner and to improve the conductivity by precipitating vanadium, titanium, chromium, and molybdenum.
  • All of these are detrimental to the electrical conductivity at their usual impurity levels in commercial grade aluminium.
  • Boron can be used alone (at levels of 0.005 to 0.1 %) as a grain refiner during solidification,  Use of CERALOY-B is far more environment friendly than the conventional salt based refiners.
  • Since no chemical reaction is involved, crucible life can be improved.

Casting with improved and consistent mechanical and metallurgical properties :-

  • CERALOY-B improves as –cast mechanical properties such as tensile Strength and elongation.
  • The longer Grain refining effect gives consistent metallurgical and mechanical properties of the castings.
  • Use of CERALOY-B gives cleaner working environment since no chemical reaction is involved.
  • Prepare the desired alloy composition.
  • Follow the normal fluxing and cleansing procedure recommended by using suitable flux from CERAFLUX range
  • Degas the melt with degassing tablet by using suitable grade from CERAFLUX range and dross off using small quantity of CERAFLUX-11.
  • After the degassing operation, add CERALOY-B and rabble it to ensure homogeneity of the composition.
