Modulus of elasticity and Poisson's coefficient of non-ferrous metals

The tables below show the values of Young's modulus (modulus of elasticity) and Poisson's ratio at room temperature for several nonferrous metals used in engineering. The material properties are expressed in average values or in ranges that can vary significantly depending on the processing and of the material's quality. The exact values can be measured by the non-destructive Sonelastic® Systems testing at room temperature, as well at low and high temperatures.
