ABSTRACT:
A method for preparing Al—Si alloys by introducing into the molten aluminum, at a temperature of between 700 and 850° C., metallurgical silicon particles having a granulometry of less than 10 mm. The silicon particles, upon reaching the temperature of the molten aluminum, have the property of fragmenting into smaller particles.
