Custom Zamak 5 Zinc Alloy Die Casting

Professional Custom Zamak 5 Zinc Alloy Die Casting | Jiazhan Die Casting

Zamak 5 (ZnAl4Cu1) is the go-to zinc alloy when a part needs more strength than Zamak 3 can give. The small copper addition raises tensile strength and hardness while keeping zinc's excellent castability, dimensional precision, and plating finish — so it's the choice for tool attachments, small gear housings, brackets, and fittings that take real mechanical load. We specialize in custom Zamak 5 zinc alloy die casting for the U.S. and global markets, producing components that meet the demand for superior mechanical properties without giving up the fine detail and surface finish zinc is known for.
