Zinc is a chemical element with the symbol Zn and atomic number 30. It is a bluish-white metal that is commonly used in a variety of applications, including electrical and electronic components, galvanizing (coatings to protect against corrosion), batteries, and alloys with other metals. Zinc is also used as a substrate material in some applications due to its good thermal conductivity and low cost. It is important to note that Zinc is a relatively soft metal, so it may not be suitable for applications that require high mechanical strength or durability. Additionally, Zinc is a relatively reactive metal, so it may corrode or react with other materials if not properly protected or treated.
