2020-1-12 Zinc (Zn) is an abundant metal, found in the Earth’s crust, with a myriad of industrial and biological uses. At room temperature, zinc is brittle and blue-white in color, but it can be polished to a bright finish. A base metal, zinc is primarily used to galvanize steel, a process that protects the metal against unwanted corrosion.

2020-3-31 Zinc is a dense metal, though less dense than iron, meaning that it is heavy and will sink in water. The physical properties of zinc changes some depending on the temperature it is exposed to. Normally hard and brittle, it becomes malleable between 212 and 320 degrees Fahrenheit. Once the metal hits 410 degrees it becomes brittle once more.
