Webbthe important properties of metals, ceramics, and polymers. Their detailed structures will be described in Section 1.3. The differences in their structure are responsible for differences in properties. Metals have densities ranging from 3 to 19 g/cm−3; iron, nickel, chromium, and niobium have densities ranging from to 7 to 9 g/cm−3; alu- Webb20 juli 1998 · polymer, any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, that are multiples of simpler chemical units called monomers.
