The Properties and Uses of Zinc Metal

Strength: Zinc is a weak metal with a tensile strength less than half that of mild carbon steel. It is generally not used in load-bearing appliions, although inexpensive mechanical parts can be die cast from zinc. Toughness: Pure zinc has low toughness and is generally brittle, but zinc alloys generally have high impact strength compared to other die casting alloys.
