Physical Properties Mechanical Properties Other Designations Applications. It is a reasonable conductor of electricity. The chemical properties of zinc make it useful for galvanization, protecting metals which are more susceptible to corrosion. A traditional dry cell has an outer zinc casing acting as the anode (confusingly the anode, usually thought of as positive, is the negative end of a battery), while a carbon rod provides the cathode, the positive electrode. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. By 1837, Stanislas Sorel had named his new process of zinc-plating "galvanization" after Luigi Galvani, who had discovered the animating effect of electricity while autopsying frogs. Zinc is critical for all life on Earth, and it's used in more than 300 enzymes. The oxide and zinc centres are tetrahedral. Zinc Alloy 2, also known as Kirksite or Zamak 2 (ASTM AC43A), is the highest strength and hardness of the Zamak family. Ra­dioac­tive 65Zn has a half-life of 244 days.
