TITANIUM: TOMORROW'S SPRING MATERIAL?

One of the popular means of reducing automobile weight has been substitution of lighter weight materials for conventional ones. Titanium, since it is available in as wide a range of strengths as steel yet is only 56% as dense, is such a substance. A substitution for steel on an equal strength basis could save 44% in weight. However, in most structural applications stiffness is also important and, since titanium's elastic moduli are half those of steel, a gauge-for-gauge substitution realizing this full weight saving is impossible. An exception to this is the case of springs, for which lower elastic properties increase potential weight savings.
