What is Zinc
Zinc (Zn) is a metal found in the Earth’s crust with large variety of industrial and biological uses. At room temperature, zinc is brittle and usually a blue-white in colour.
Zinc is primarily used in the process of galvanizing steel, a commonly used process to protect metal against corrosion from oxidisation. Alloys of zinc including brass which is commonly used of musical instruments.
Some interesting facts about zinc taken from TheBalance.com are:
- Strength: Zinc is a weak metal with tensile strength less than half that of mild carbon steel. It is generally not used in load-bearing applications, 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.
- Ductility: Between 212-302 oF zinc becomes ductile and malleable, but at elevated temperatures reverts to a brittle state. Again, zinc alloys greatly improve on this property over the pure metal, allowing more complex fabrication methods to be used.
- Conductivity: Zinc’s conductivity is moderate for a metal. Its strong electrochemical properties, however, serve well in the galvanizing process and alkaline batteries
