The use of zinc as a structural metal has been militated against by two of its properties, namely, its low tensile strength and its susceptibility to grain growth. The importance of these factors can be appreciated when it is realized that the tensile strength of coarsely crystalline cast zinc is 4,000 pounds per square inch, while finely crystalline cast zinc has a tensile strength of 12,000 pounds per square inch.
