Grain refiners

Listing ID #3477932

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.
