1. A method of refining the primary silicon in hypereutectic aluminium-silicon alloys by means of products based on phosphorus and magnesium, characterised in that the product based on magnesium is added to an alloy which has been prerefined by the product based on phosphorus, and that this is done immediately before casting.
