Zinc alloys can be ideal for the die casting process. It has high fluidity and when molten flows to ensure part feature precision. Also, unlike other processes, you can easily machine features or cast in features such as threads or intricate elements to a part. This blog post will explore ten reasons behind the zinc die casting popularity.
What is zinc vs a zinc alloy?
Zinc is an element and metal that naturally occurs in nature and is mined much like iron, silver or gold. A zinc alloy combines zinc with other metals to achieve a more precise chemistry or mixture to achieve ideal characteristics of strength and fluidity and corrosion resistance.

Designers and engineers choose zinc die-casting for its inherent benefits in component design. Principally, zinc die-castings are strong, economical, and often cast to exact shapes without additional machining needs.
10 Reasons Why Think Zinc for Casting Parts
Strength: Zinc Alloys Are Stronger
Zinc alloys are stronger per weight than other materials. This produces a casting with greater impact resistance and rigidity than its plastic and aluminum counterparts.
Cast With Thinner Walls:
Zinc alloys may be cast with thinner wall cross sections than other metals. Therefore, since zinc is stronger than aluminum and can be cast with thinner walls it is conceivable that less material would be suitable for designs in zinc alloys rather than other materials.
Also, zinc is not prone to have “sink” defects such as the case with plastics when wall.
Long Tool Life with Zinc Casted Parts
A typical zinc mold can last 10 times as long as an aluminum mold. It has longer life because it is less abrasive and has a lower melting temperature and thus less thermal shock. If tool costs are a sizable part of production expenses, choosing zinc alloys over aluminum alloys can save manufacturers significantly.
Especially in high-volume scenarios, zinc offers substantial cost advantages.
