ABSTRACT:
The present invention relates to a method for grain refining of aluminium and aluminium alloys wherein a siliconboron alloy containing between 0.01 to 4.0 % by weight of boron is added to molten aluminium or aluminium alloy in such an amount that the resulting melt of aluminium or aluminium alloy contains at least 50 ppm boron. The invention further relates to a grain refining alloy for aluminium and aluminium alloys which grain refining alloy is a siliconboron alloy containing between 0.01 and 4.0 % by weight of boron.
