Fine Ceramics: Strong but Light
Fine Ceramics (also known as “advanced ceramics”) are lighter than high-strength metals. Within the same volume, many Fine Ceramic materials weigh only half as much as metal counterparts.

Applications: Turbocharger rotors and other related products.

Specific Gravity
Density refers to a material's mass per cubic centimeter, while specific gravity refers to the density ratio between a given material and water, where water is assigned a value of 1. Many Fine Ceramic materials have specific gravities less than half those of ferrous metals.
