Custom ZnAl4Cu1 Zinc Alloy Die Casting

Custom ZnAl4Cu1 Zinc Alloy Die Casting | Jiazhan Die Casting

ZnAl4Cu1 is the alloy Europeans know as Zamak 5 — and it's a step up from the softer, more ductile Zamak 3. The small copper addition lifts strength and hardness while keeping the good castability and plating finish zinc is known for, which makes it a natural pick for electronic components that take real mechanical load — connector bodies, shielding cans, and structural brackets that also need a clean plated look. We produce high-volume ZnAl4Cu1 components to the stringent quality standards the European market expects, where a part has to be strong, dimensionally stable, and finished to a high standard all at once.
