Elongation of Common Zinc Alloys
Zinc alloys are known for their high strength and hardness, but they may exhibit lower ductility and elongation at break compared to some other metals. The specific elongation at break for zinc alloys can vary depending on the alloy composition, processing conditions, and heat treatment.
The following table provides a curated list of elongation at break values for different zinc alloys.
