Melted and re-solidified zinc die-cast alloy in slab or pig form (≥90% Zn). Pre-refined secondary alloy chargeable straight into die-cast furnaces.

Scull — Melted Zinc Die-Cast Alloy (Slab/Pig Form): Melted and re-solidified zinc die-cast alloy in slab, ingot, or pig form, with a minimum specified zinc content of approximately 90%. Scull arises from partial melting and solidification operations at scrap processing facilities or die-casting plants, producing a pre-refined secondary alloy that can be charged back into a die-casting furnace with minimal additional processing.
