Hardness
There are two materials which are only surpassed by diamond in terms of hardness – Boron Carbide (B4C) and Silicon Carbide (SiC). Precision Ceramics DuraWear™ a Boron Carbide based composite ceramics and Durashock™ a Boron Carbide/Silicon Carbide ceramic composite are extremely hard and only available at Precision Ceramics.
Materials Ranked by Hardness
In terms of hardness, between DuraWear™ and Durashock™ there’s not much to choose between them but each has its own specific advantages in terms of properties and applications. This is followed by Silicon Carbide (SiC), one of the lightest, hardest and strongest advanced ceramics.

Compressive Strength
Compressive strength is the capacity of a material to withstand loads tending to reduce size. Explained differently, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart).
Density
Density is the mass of a material per unit volume. The unit of measurement can be expressed in different ways and is referred us as g/cm3 but another measurement value is kg/m3.
Fracture Toughness
The ability to resist fracture is a mechanical property of materials known as fracture toughness. For advanced ceramics it uses a critical stress intensity factor known as KIC where the fracture normally occurs at the crack terminations.
