Cemented Carbide Overview

Base_Materials_opt.jpg

Hyperion Materials & Technologies has over 60 years of experience in the development, manufacturing, and application of cemented carbide (also known as solid carbide or tungsten carbide (WC)) wear components (wear parts). Cemented carbide is one of the most successful composite engineering materials ever produced. Cemented carbide’s unique combination of strength, hardness, and toughness satisfies the most demanding applications.  

A key feature of the cemented carbide is the potential to vary its composition so that the resulting physical and chemical properties ensure maximum resistance to wear, deformation, fracture, corrosion, and oxidation. In addition, the wide variety of shapes and sizes that can be produced using modern powder metallurgical processing offers tremendous scope to design cost-effective solutions to many of the problems of component wear and failure encountered in both the engineering and domestic environment.

Hyperion’s cemented carbides and their properties can be customized by changing the binder content and tungsten carbide to achieve the highest resistance to wear, fracture, heat, corrosion, and oxidation.

Hyperion is a world leader in cemented carbide. By involving us in the early development stages, we can help you select the best material for your application and optimize the design of your component to improve the weight, efficiency, and cost.
