Abstract
A process for producing an Al--Si casting alloy. An alloy is heated to a first temperature to produce a melt and over heat it. A modifier is then added to the melt. The modifier includes an ultra disperse powder capable of remaining in a solid state during the entire alloy production process. The alloy is treated with ultrasound. The alloy is degassed or fluxed, and the melt is poured.
