Zamak 2

Zamak 2 is one of the strongest and hardest alloys in the Zamak family, consisting primarily of zinc with aluminum, copper, and magnesium. Compared with Zamak 3 and Zamak 5, it provides higher strength, hardness, and wear resistance while maintaining excellent die-casting characteristics.

Appearance & Properties

Color: Silver-gray to bright silver-gray

Density: Approx. 6.8 g/cm³

Tensile Strength: Approx. 350–400 MPa, depending on condition and manufacturing process

Hardness: Relatively High

Wear Resistance: Good

Corrosion Resistance: Moderate to Good

Machinability: Good

Die Castability: Excellent

Magnetism: Non-magnetic

Surface Finishes: Polishing, electroplating, painting, powder coating, passivation, etc.

Typical Applications

Zamak 2 is widely used in automotive, electrical and electronics, hardware, home appliances, locks, industrial equipment, and consumer products.

Typical parts include gears, lock components, mechanical housings, connectors, handles, brackets, decorative components, and precision die-cast parts.

Advantages

• High strength and hardness within the Zamak family

• Good wear resistance

• Excellent die-casting and dimensional capabilities

• Suitable for complex and thin-wall precision components

• Wide range of surface-finishing options

Limitations

• Relatively high density for lightweight applications

• Limited mechanical performance at sustained high temperatures

• Lower corrosion resistance than materials such as stainless steel

• Long-term dimensional stability and aging behavior should be considered
