Modifiers for aluminum alloys
The addition of sodium to hypo-eutectic and eutectic aluminum-silicon alloys modifies the structure and greatly improves mechanical properties and feeding characteristics. Foseco’s modifying products may be introduced into the melt in the form of powder and granular fluxes, tablets and metallic sodium.
