Aluminum VS Zinc Alloy Die Casting: How to Pick Suitable Raw Material
Many global purchasing engineers get confused when choosing aluminum alloy or zinc alloy for custom die casting projects. Proper material selection can control production cost, improve product service life and meet assembly tolerance requirements.
1. Aluminum Alloy Die Casting
Common grades: A380, ADC12, A413 aluminum alloy.
- Advantages: Light weight, excellent heat dissipation, good corrosion resistance, high structural strength.
- Processing feature: Adopt cold-chamber high-pressure die casting, match large-size housing, heat sink, auto transmission parts. After CNC secondary machining, tolerance can reach ±0.01mm.
- Main application: Automobile spare parts, home appliance shell, mechanical equipment heat dissipation components, new energy equipment parts.
- Surface finish support: Anodizing, powder coating, sandblasting.
2. Zinc Alloy Die Casting
Common grades: Zamak3, Zamak5 zinc alloy.
- Advantages: High dimensional accuracy, smooth casting surface, good ductility, easy electroplating and polishing.
- Processing feature: Hot-chamber die casting with fast production cycle, low mold cost for small precision parts.
- Main application: Small electronic hardware, connector accessories, precision decorative parts, household appliance small fittings.
- Surface finish support: Bright chrome plating, nickel plating, high-gloss polishing.
3. Simple Selection Suggestion
- Large size, heat dissipation needed, lightweight demand → Choose Aluminum Alloy
- Small precision part, high appearance requirement, electroplating needed → Choose Zinc Alloy
