Mechanical Properties
Specific Gravity (Density)
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.
