This page explains how Zinc Die Casting is classified within Basic Metal Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
Zinc die casting is a high-precision metal forming process that produces complex, durable parts with excellent dimensional accuracy and surface finish.
Technical details and manufacturing context for Zinc Die Casting
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Wall Thickness | 0.5–3.0 mm | Typical range for zinc die castings; thinner walls possible with design optimization. |
| Dimensional Tolerance | ±0.05 mm | Typical tolerance for small to medium parts; tighter tolerances achievable.ISO 8062-3 |
| Surface Roughness (Ra) | 0.8–1.6 μm | As-cast surface finish; can be improved by polishing or coating.ISO 1302 |
| Tensile Strength | 280–400 MPa | Depends on alloy; Zamak 3 typically 283 MPa, Zamak 5 331 MPa.ASTM B86 |
| Yield Strength | 200–300 MPa | Typical range for zinc die casting alloys.ASTM B86 |
| Elongation at Break | 2–10 % | Varies with alloy; Zamak 3 has ~10%, Zamak 5 ~7%.ASTM B86 |
| Hardness (Brinell) | 82–105 HB | Typical range for zinc die casting alloys.ASTM B86 |

Common materials include Zamak 3 (ZnAl4Cu1), Zamak 5 (ZnAl4Cu1), Zamak 2 (ZnAl4Cu3), ZA-8 (ZnAl8Cu1), and zinc-aluminum alloys ZA-12 and ZA-27. These grades differ in alloying elements, affecting mechanical properties and corrosion resistance.
Typical dimensional tolerance is ±0.05 mm for small to medium parts, as per ISO 8062-3. Tighter tolerances may be achievable with design optimization and process control.
The maximum continuous operating temperature is typically 100–120°C. Higher temperatures can reduce mechanical properties, so it is important to consider the application's thermal environment.
Relevant standards include ASTM B86, EN 12844, ISO 301, and GB/T 13818. These standards provide specifications for material grades, mechanical properties, and testing methods. Always verify compliance with the manufacturer.
