Description

Zamak 2 is a high-strength zinc alloy known for its superior mechanical properties, excellent dimensional stability, and corrosion resistance, making it ideal for demanding precision die-cast parts.

Key Characteristics of Zamak 2

Zamak 2 is a high-quality zinc alloy with copper, aluminum, and magnesium. It is known for its outstanding strength and resistance to wear, making it suitable for heavy-duty applications.

Zamak 2’s combination of copper, aluminum, and magnesium enhances its strength and wear resistance, while maintaining excellent casting fluidity for intricate mold designs.

Chemical Composition of Zamak 2

Zamak 2 has a relatively high copper content compared to other Zamak alloys, providing enhanced strength and impact resistance. This alloy also has excellent casting characteristics that make it ideal for thin-walled sections.

Mechanical Properties of Zamak 2 Zinc Alloy

Zamak 2 is commonly used for precision cast parts requiring high strength, dimensional accuracy, and durability.

The high tensile strength and fatigue resistance of Zamak 2 make it ideal for components exposed to high mechanical stress and wear.

Benefits of Using Zamak 2 in Die Casting

• High Strength: Zamak 2 provides superior mechanical strength to other zinc alloys, making it ideal for load-bearing applications.

• Excellent Dimensional Stability: It retains its shape and size even under high temperatures, making it suitable for precision die casting with tight tolerances.

• Corrosion Resistance: Zamak 2 is more corrosion-resistant than many other zinc alloys with high copper content, offering long-term durability.

• Good Fluidity: Zamak 2's fluidity makes it suitable for casting intricate and complex geometries.

• Impact Resistance: The alloy’s high strength and durability ensure it performs well in high-impact applications.

Typical Applications of Zamak 2 Die Cast Parts

Due to its superior strength and dimensional stability, Zamak 2 is widely used in industries that require robust, high-performance parts:

• Automotive: Transmission parts, suspension components, engine brackets, and structural elements

• Aerospace: Aircraft engine components, fittings, and housings for critical systems

• Industrial Equipment: Pumps, valves, and high-stress components in machinery

• Electronics: Durable housings for electronic devices and connectors

• Marine: Seawater-resistant fittings, pump casings, and outdoor components

The enhanced strength and impact resistance of Zamak 2 make it ideal for structural parts that need to withstand heavy loads and harsh conditions.

CNC Machining Considerations for Zamak 2

Zamak 2 is relatively easy to machine, but its higher copper content can cause some tool wear over time. Proper tooling and machining techniques are essential for achieving optimal results.

Machining Recommendations:

• Tooling: Use carbide or TiAlN-coated carbide tools to mitigate the effects of wear from copper.

• Cutting Speed: Milling: 250–500 m/min; drilling: 100–150 m/min

• Feed Rate: 0.05–0.15 mm/rev, depending on the complexity of the part and tool diameter

• Coolants: Use water-based coolants to keep the temperature under control and prolong tool life

• Surface Finish: Achievable Ra ≤ 1.6 µm for parts requiring a smooth, functional surface

• Tolerance: ±0.03 mm typical for critical features

Neway’s CNC machining services ensure high-quality machining for Zamak 2 die-cast parts, with precise tolerances and excellent surface finishes.

Surface Treatments for Zamak 2 Parts

To further enhance the performance of Zamak 2, various surface treatments can be applied:

• Anodizing: Improves corrosion resistance and can add a decorative finish.

• Powder Coating: Adds durability and provides extra protection for outdoor or high-stress applications.

• Painting: Adds aesthetic value and UV protection for exterior parts.

• Tumbling: Used to remove flash and burrs for smoother finishes before coating.

All surface treatments are tested for durability, adhesion, and wear resistance according to ISO and ASTM standards.
