Shenzhen Alu Rapid Prototype Precision Co., Ltd.

In the context of creating a zinc die casting prototype for applications like selecting the appropriate zinc alloy and preparing the material are critical steps to ensure the prototype meets performance, durability, and cost requirements.

Materials for Zinc Die Casting Prototypes

Zinc die casting primarily uses zinc-based alloys, with the Zamak family being the most common due to their excellent castability, strength, and cost-effectiveness. These alloys are ideal for robotic components like housings, gears, brackets, or sensor mounts due to their high precision, thin-wall capability, and good mechanical properties. Below are the key zinc alloys used:

1. Zamak 3 (AG40A)

Composition: ~96% zinc, 4% aluminum, trace amounts of magnesium and copper.

2. Zamak 5 (AG40B)

Composition: ~96% zinc, 4% aluminum, 1% copper, trace magnesium.

3. Zamak 2 (AG43A)

Composition: ~96% zinc, 4% aluminum, 3% copper, trace magnesium.

4. ZA Alloys (e.g., ZA-8, ZA-12, ZA-27)

Composition: Higher aluminum content (8-27%) with zinc, copper, and magnesium.

For zinc die casting prototypes, Zamak 3 and Zamak 5 are the primary materials due to their castability, strength, and cost-effectiveness, with ZA-8 as an option for lightweight, high-strength parts.
