Popular Zinc Alloys For Custom Zinc Die Casting Projects
Different zinc alloys provide different combinations of strength, hardness, wear resistance, dimensional stability, surface finishing performance, and casting characteristics. Selecting the right alloy helps OEM customers achieve reliable part performance, consistent casting quality, and cost-efficiency production on scale.
| Zinc Alloy Model | Feature | Typical Application | Process Type |
|---|---|---|---|
| Zamak 3 | Best all-rounder | General die casting | Hot Chamber die casting |
| Zamak 5 | Higher strength | Automotive / industrial | Hot Chamber die casting |
| ZA-8 | Balanced engineering alloy | Precision strong parts | Hot & Cold Chamber Die Casting |
| ZA-12 | Strong + wear resistant | Gears / machinery | Cold chamber die casting |
| ZA-27 | Higher Aluminum element content, Maximum strength | Heavy-duty parts | Cold chamber die casting |
Zamak alloys have excellent ductility, and can be efficiently formed into complex, high-precision die-cast parts at relatively low melting temperatures. These zinc die casting parts are easily polished and accept various eletroplating processes. The die casting process has a longer tooling life and have a lower tooling allowance and Less tooling repaire and matainence.
ZA Zin-Aluminum alloys require higher melting temperature and make strong precision high aluminum zinc die cast parts, enhance corrosion resistance, hardness and stentile-strength, and can be used for some specific requirements. Its high hardness makes enhancement of polishing cost. And working at higher temperture, the die casting die is needed for regular repair and maintance.
