Shijiazhuang TJJ TRADE CO., LTD. combines over two decades of foundry expertise with a dedicated export team to provide the highest standard of zinc die cast components.
Industry Pain Points in Sourcing Zinc Die Castings
Overseas buyers often face these recurring challenges when sourcing from China:
- Inconsistent dimensional quality – Variation between production runs leads to assembly failures.
- Long and unreliable lead times – Missed seasonal windows or project deadlines.
- Poor communication – Language barriers and time zone delays.
- Hidden costs – Additional tooling, mold changes, or shipping surprises.
- Lack of after-sales support – No technical assistance or rapid replacement for defects.
TJJ’s zinc alloy die casting service directly addresses each of these pain points with a structured, transparent process.

🌐 China Supply Chain Advantage
Located in Shijiazhuang, we source die casting alloys from local suppliers with lower logistics costs. This translates to competitive FOB pricing without compromising quality. We handle all export documentation, customs clearance, and sea/air freight coordination.
Zinc Alloy Grades & Typical Applications
We primarily cast Zamak 3, Zamak 5, and Zamak 7 – the most common zinc die casting alloys. The table below summarizes key properties:
| Grade | Tensile Strength (MPa) | Elongation (%) | Typical Applications |
|---|---|---|---|
| Zamak 3 | 268 | 10 | Hardware, automotive parts, locks, door handles, toy components |
| Zamak 5 | 328 | 7 | Gears, brackets, electrical enclosures, structural parts requiring higher strength |
| Zamak 7 | 283 | 13 | Thin-walled intricate parts, electronics housings, medical device components |

Zinc vs. Aluminum vs. Iron Die Casting – A Quick Comparison
To help you decide the best material for your project, we have compiled a comparative overview:
| Feature | Zinc Alloy | Aluminum Alloy | Cast Iron |
|---|---|---|---|
| Density (g/cm³) | 6.6 | 2.7 | 7.1 |
| Typical Wall Thickness (mm) | 0.5 – 2.0 | 1.0 – 3.0 | 3.0 – 6.0 |
| Surface Finish | Excellent (as-cast or plated) | Good (requires finishing) | Fair (coating recommended) |
| Corrosion Resistance | High (with proper coating) | Very high (natural oxide) | Low (needs paint/galvanizing) |
| Relative Cost (per piece) | Moderate | Moderate | Low |
Cost and property data are indicative and may vary with design complexity. Contact us for a detailed comparison for your specific part.
