Die-cast zinc is not highly malleable compared to some other metals. Zinc alloys used in die-casting, such as Zamak (typically containing zinc, aluminum, magnesium, and copper), are valued for their strength, hardness, and ability to form precise, complex shapes. However, these alloys are relatively brittle and have low ductility, meaning they don’t deform easily under stress without cracking or breaking. Their tensile strength is typically 40,000–55,000 psi (276–379 MPa), but their elongation (a measure of malleability) is only about 1–3%, much lower than malleable metals like copper (20–50% elongation) or annealed steel.

Once cast, zinc parts are rigid and maintain their shape well, which is great for applications like automotive components, hardware, or fittings, but they’re not suited for processes requiring bending or reshaping.
