Characteristics and Advantages of Zinc Alloy for Decorative Products

Material Properties

Alloy Composition

- Primary component: Zn content typically >96%, with additions of Al (3-5%), Cu (1-3%), and Mg (0.03-0.06%)
- Common grades: ZA8 (ZnAl8Cu1), ZA12, etc.

Physical Properties

- Density: 6.4–6.6 g/cm³ (only 80% of stainless steel)
- Melting point: 380–450℃ (suitable for die-casting)
- Hardness: 80–120 HB (meets decorative requirements)

Manufacturing Advantages

Formability

- Excellent die-casting fluidity (fill ratio up to 95%+)
- Minimum achievable wall thickness: ≤0.5mm

Surface Finish

- Highly polished mirror effect ( - Electroplating adhesion strength: ≥15 MPa (ASTM B571)

Cost Efficiency

- Material cost: 40-60% lower than brass
- Die lifespan: 50,000–100,000 cycles (vs. 20,000 for aluminum)

Decorative Performance

Design Flexibility

- Replicates intricate textures (e.g., 100–300DPI laser patterns)
- 85% shrinkage consistency vs. master model

Corrosion Resistance

- Salt spray test: 72–240 hours (ASTM B117)
- Chromate conversion coating increases protection 5–8×

Weight Advantage

- 30% lighter than equivalent brass components
- Optimized for wearables (e.g., pendant average weight 8–12g)

Environmental Compliance

- RoHS-certified cadmium content: <50ppm
- 100% recyclable (reclamation energy usage: 5% of primary production)

Applications: Fashion jewelry, luxury hardware, awards/trophies, architectural embellishments.
