Z-12 Zinc Alloy Slabs
Z-12 slabs are unwrought zinc alloy forms containing approximately 86% zinc and 12% aluminum, with trace elements, for sand casting applications. Zinc predominates by weight, and the total other elements exceed 2.5%, meeting the definition of a zinc alloy under Chapter 79. These slabs are used in industrial castings requiring high impact resistance.
