The most common zinc alloys used industrially are Zamak alloys (an acronym derived from the German names of its main alloying elements: Zink, Aluminium, Magnesium, Kupfer/Copper). The Zamak series includes Zamak 2, 3, 5, and 7, each with slightly different compositions and properties:

• Zamak 3: The most widely used zinc alloy, offering a good balance of ductility, impact strength, and excellent corrosion resistance. It’s well-suited for general die casting.
• Zamak 5: Contains added copper (typically around 1%), which increases its hardness, tensile strength, and wear resistance compared to Zamak 3, while slightly reducing ductility. It’s often used for plated parts due to its superior surface finish.
• Zamak 2: Contains a higher copper content and a small amount of tin, making it the hardest Zamak alloy with excellent bearing properties, though less ductile.
• Zamak 7: Features controlled additions of nickel and magnesium, offering improved ductility and fluidity compared to Zamak 3, making it ideal for intricate die-cast parts.

Other zinc alloys exist, such as those used for galvanizing (often with small additions of aluminum and iron) or specialized applications requiring specific metallurgical characteristics. The term ‘hard zinc’ generally refers to these alloys engineered for enhanced mechanical properties.

Properties and Advantages

Hard zinc alloys offer several advantages that make them highly desirable in manufacturing:

• Excellent Strength and Hardness: Significantly harder and stronger than pure zinc, allowing them to withstand higher stress and wear.
• Corrosion Resistance: Offer good resistance to atmospheric corrosion, especially when properly finished or plated. Zamak 3 and 5 are particularly noted for this.
• Dimensional Accuracy: Ideal for die casting, allowing for the production of intricate parts with tight tolerances and excellent surface finish.
• Impact Resistance: Many zinc alloys, particularly Zamak 3 and 7, exhibit high impact strength, making them suitable for components that may experience sudden forces.
