Periodic Table

Alongside the usual atomic number, symbol, and atomic weight, this periodic table also lists mechanical properties for each element — density, specific gravity, shear modulus, bulk modulus, Young's modulus, and Poisson's ratio — the figures most likely to be useful when you're choosing or specifying a material rather than studying chemistry. These are useful starting points for hand calculations and material comparisons, though for a specific alloy or supplied material, always check the mill certificate or datasheet rather than relying on the pure-element value, since alloying can shift these properties noticeably from the base element.

FREQUENTLY ASKED QUESTIONS

Why do the mechanical properties matter for a chemical element?

Many pure elements (iron, aluminium, copper, titanium, etc.) form the base of common engineering alloys. Knowing the pure element's stiffness and density gives a useful reference point, even though the actual alloy used in a component will differ once other elements are added.

What's the difference between Young's modulus and shear modulus?

Young's modulus (E) describes a material's stiffness under direct tension or compression; shear modulus (G) describes its stiffness under shear (twisting) loads. Both are related through Poisson's ratio for an isotropic material. See our Engineering Glossary for full definitions.

Where can I find the mechanical properties of a specific alloy, rather than a pure element?

See our Metal Properties and Material Strength pages for alloy-specific data.
