DuraWear – A Boron Carbide and Silicon Carbide hybrid

Boron Carbide and Silicon Carbide Hybrid

Durawear is an engineered high quality ceramic composite, made from a hybrid of Boron Carbide (B4C) and Silicon Carbide (SiC).

Durawear has hardness levels approaching that of Boron Carbide (one of the hardest materials on the planet) but with a fracture toughness of over double that of Boron Carbide.

Using a combination of Silicon Carbide and Boron Carbide gives the benefits of both enabling an easy formed ceramic body to be shaped and machined prior to sintering, with a consistent shrinkage and good density, high hardness, fracture toughness and wear resistance.

Applications include shot blast nozzles, wear parts, high temperature wear parts, advanced armor shielding, jigging and liners.

Durawear has been developed to deliver a material that takes the best from both materials combined in a strong fully dense structure ideal for mechanical wear parts, that are subject to more than just abrasive wear.
