Yes, die-cast zinc is strong and durable for many applications. Zinc alloys commonly used in die-casting, such as Zamak (typically a mix of zinc, aluminum, magnesium, and copper), have a tensile strength of approximately 40,000–55,000 psi (276–379 MPa), which is comparable to or stronger than some low-carbon steels and significantly stronger than many plastics. These alloys also offer good impact resistance and hardness, making them suitable for components like automotive parts, hardware, gears, and consumer electronics housings.

However, die-cast zinc is not as strong as high-strength steels or certain forged metals, and its strength can be affected by casting defects like porosity.

 Additionally, as noted earlier, it has low malleability (1–3% elongation), so it’s prone to cracking under excessive bending or deformation. Compared to die-cast aluminum (20,000–45,000 psi), zinc is generally stronger, but it’s less corrosion-resistant in harsh environments unless coated.
