Zinc is a chemical element with the symbol Zn and atomic number 30. It is a bluish-white metal with a low melting point of 420 °C. Zinc is popular in many applications for its corrosion resistance. It is also a necessary trace element for proper functioning of the human body and other biological processes.
Zinc is also used for medical equipment, rubber products, paint pigments and ceramics. One interesting fact about zinc itself is that it is the second most abundant trace metal in the human body, after iron. Some applications of commercially available zinc alloys are given below. Table 2. Typical applications of zinc alloys.
