What is Zinc Alloy Die Casting

Why Choose Zinc Alloy Die Casting

Zinc alloy die casting offers an ideal balance of precision, efficiency, and cost control. Its low melting point reduces energy consumption during production, while excellent fluidity enables complex geometries, thin walls, and consistent dimensional accuracy—often replacing more complex or costly manufacturing processes.

  • Low melting point for energy-efficient production

  • High dimensional accuracy and long-term stability

  • Excellent thin-wall and complex geometry capability

  • Superior strength and hardness compared to many alloys

  • Good corrosion resistance for extended service life

  • Excellent surface finish for plating, coating, and painting

  • Strong electrical and thermal conductivity

  • Easy secondary processing and assembly

  • Fully recyclable and environmentally responsible

Zinc Alloy Properties and Applications

Zamak 2 (ASTM AC43A)

Zamak 2 (ASTM AC43A)

Zamak 2 offers the highest strength and hardness within the Zamak alloy family. Its higher copper content provides improved wear resistance and mechanical durability, making it suitable for applications requiring superior load-bearing performance, tight tolerances, and long service life.

Zamak 3 (ASTM AG40A)

Zamak 3 (ASTM AG40A)

Zamak 3 is the most widely used zinc die casting alloy due to its excellent balance of strength, ductility, dimensional stability, and castability. It delivers consistent performance across a wide range of applications and is often the preferred starting point for zinc alloy die casting projects.

Zamak 5 (ASTM AC41A)

Zamak 5 (ASTM AC41A)

Zamak 5 provides higher strength and hardness than Zamak 3, with slightly reduced ductility. It is commonly selected when enhanced mechanical performance is required while maintaining good castability and surface finish.

Zamak 7 (ASTM AG40B)

Zamak 7 (ASTM AG40B)

Zamak 7 is a high-purity variation of Zamak 3 with reduced magnesium content and tighter impurity control. This results in improved casting fluidity, enhanced ductility, and superior surface finish, making it well suited for cosmetic or thin-wall components.

ZA-8 (Zinc Aluminum Alloy)

ZA-8 (Zinc Aluminum Alloy)

ZA-8 contains significantly higher aluminum content than traditional Zamak alloys and offers superior strength, wear resistance, and creep performance. It is the only ZA alloy compatible with hot-chamber die casting, allowing higher productivity and reduced manufacturing cost.

ACuZinc5

ACuZinc5

ACuZinc5 is a high-performance zinc alloy developed for demanding applications requiring excellent creep resistance, surface hardness, and lubricity. Its mechanical stability under sustained load makes it suitable for long-term, high-stress operating environments.

EZAC

EZAC

EZAC is an advanced hot-chamber zinc die casting alloy designed for superior creep resistance, high yield strength, and exceptional hardness. It provides enhanced dimensional stability under continuous stress and elevated temperature conditions.

ZA-27 (Zinc Aluminum Alloy)

ZA-27 (Zinc Aluminum Alloy)

ZA-27 contains approximately 27% aluminum and offers significantly higher strength and wear resistance compared to standard Zamak alloys. It is typically gravity cast or cold-chamber die cast and is chosen for applications requiring exceptional mechanical performance.

BERIC

BERIC

BERIC is a premium zinc-based alloy engineered for outstanding wear resistance, tensile strength, and hardness. It is suitable for applications requiring long service life, mechanical reliability, and resistance to repeated mechanical stress.

Kayem

Kayem

Kayem is a zinc-based alloy containing zinc, aluminum, and copper, offering enhanced strength and hardness compared to standard Zamak grades. It is often selected for applications requiring higher mechanical durability while maintaining good castability.

ZP0410

ZP0410

ZP0410 is a versatile zinc die casting alloy providing a balanced combination of strength, castability, and dimensional stability. It performs reliably across a broad range of die casting applications and industries.

ZP0430

ZP0430

ZP0430 is a high-strength zinc alloy comparable to Zamak 2, offering excellent hardness and mechanical performance. It is well suited for components subjected to high loads and demanding operating conditions.
