Zinc Alloy Materials

What Is Zinc Alloy Material?

Zinc alloy is a high-fluidity, high-formability alloy material, serving as a core raw material for precision manufacturing. It offers excellent castability and dimensional stability, enabling the production of complex, thin-walled parts with tight tolerances. It supports high-precision die-casting, CNC machining and surface finishing processes, achieving strict tolerances up to ±0.005mm, and is widely used in electronics, automotive, hardware and consumer goods fields, making it an ideal choice for manufacturing cost-effective, durable and aesthetically pleasing components.

CNC Machining Methods For Zinc Alloy

Zinc Alloy CNC Turning

A zinc alloy workpiece is rotated while a stationary cutting tool removes material, producing smooth, high-precision cylindrical components. Commonly used for creating shafts, fasteners, and rotational hardware parts with excellent surface finish.

Zinc Alloy CNC Milling

Involves rotating a cutting tool against a stationary zinc alloy workpiece to remove material. Ideal for complex geometries, including custom housings, brackets, and intricate structural parts with tight dimensional accuracy.

Zinc Alloy Die Casting (Post-Machining)

Combines high-pressure die casting for near-net-shape production with secondary CNC finishing. Used to achieve ultra-precise tolerances, smooth surfaces, and detailed features on mass-produced zinc alloy components, balancing efficiency and accuracy.

Zinc Alloy CNC Drilling & Tapping

Utilizes specialized drill bits and taps to create precision threaded holes and mounting features in zinc alloy parts. Often used to prepare components for assembly, ensuring secure and consistent thread engagement in electronic and automotive applications.
