ZINC ALLOYS FOR CASTING
DSW is a leading manufacturer in the die casting industry, pouring significant quantities of aluminium and zinc annually. Our expertise extends globally, focusing on producing high-quality die cast components. To maintain stringent quality standards, our team of highly trained metallurgists conducts continuous chemical and physical analysis to ensure that all alloys meet specifications.
We offer a diverse range of alloys to meet various application requirements
| Alloy | Standard Name | Description | Aluminum (%) | Magnesium (%) | Key Properties |
| Zamak 2 | ASTM AC43A | Highest strength and hardness of the Zamak family; also known as Kirksite or Zinc Alloy 2. | ~4.0 | ~0.02 | High strength, high hardness |
| Zamak 3 | ASTM AG40A | Most widely used zinc alloy in North America; generally the first choice for zinc die casting. | ~4.0 | ~0.04 | Good balance of properties, easy to cast |
| Zamak 5 | ASTM AC41A | Most commonly used in Europe; offers slightly higher strength than Zamak 3 due to added copper. | ~4.0 | ~0.06 | Enhanced strength, suitable for heavy loads |
| Zamak 7 | ASTM AG40B | Modified version of Zamak 3 with lower magnesium content; offers improved fluidity, ductility, and surface finish. | ~4.0 | <0.001 | High purity, better finish, high ductility |
| ZA-8 | – | Zinc aluminum alloy with approximately 8.4% aluminum; the only ZA alloy suitable for hot-chamber die casting. | ~8.4 | – | High strength, hot-chamber castable |
| ACuZinc5 | – | Developed by General Motors; known for excellent creep performance, surface hardness, and lubricity. | ~4.0 | ~0.08 | Creep resistance, high hardness, lubricity |
| EZAC | – | Hot-chamber zinc die casting alloy with superior creep resistance, high yield strength, and high hardness. | ~3.8 | ~0.04 | High yield strength, creep resistance |
| ZA-27 | – | Zinc aluminum alloy with about 27% aluminum; offers excellent strength and hardness, significantly higher aluminum than the Zamak alloys. | ~27.0 | ~0.02 | Very high strength, high aluminum content |
These alloys are carefully selected and processed for optimal performance and durability in die casting applications. Our commitment to quality and innovation drives us to exceed customer expectations and deliver superior products that meet the highest industry standards.
Prototype Manufacturing
DSW can create prototype zinc die castings in smaller quantities for clients who need low-volume production. They use various methods to achieve this, ensuring that prototypes are made accurately and efficiently. These methods include plaster injection mold castings, CNC machining and hog-outs, direct metal laser sintering (DMLS), and P-20 tooling. Each method is chosen based on the project’s unique requirements, allowing DSW to provide prototypes that closely resemble the final product while meeting the client’s deadlines and budget. This capability underscores DSW’s commitment to offering comprehensive solutions and supporting clients throughout the manufacturing process, from initial concept to production.
SURFACE FINISHING
DSW efficiently oversees customer finishing specifications to ensure timely and cost-effective compliance with part requirements. Our zinc surface finishing options encompass, but are not limited to, the following:
Powder Coating (applied electrostatically)
Wet Paint
Chromate
E-Coat
Electroless Nickel
Chrome
Silk Screening and Stenciling
EMI/RFI Shielding
