ZINC ALLOYS

Zinc-based alloys are the easiest for die casting. Ductility is high and impact strength is excellent, making these alloys suitable for a wide range of products. Zinc die casting provides thin walls and excellent surface smoothness making preparation for plating and painting relatively easy.

It is essential that only high purity (99.99 + 0/0) zinc metal be used in the formulation of alloys. Low limits on lead, tin and cadmium ensure the long-term integrity of the alloy’s strength and dimensional stability.
