Demanding applications require advanced materials. Where there is relative motion between two components, there will be friction, potential wear of either or both components, and the resulting heat and debris generation. Mechanical carbon materials involve the design of key ingredients, custom-formulated to produce a tribological solution to these conditions. Silicon Carbide materials, because of their unique hardness and stiffness, offer the potential for higher contact pressures and speeds running against the carbon materials or against themselves.

Mechanical carbons are formulated to accommodate specific application conditions. As the graphite content is increased, the materials tend to be more self-lubricating and compliant. As the graphite content is reduced toward a more carbon-based formulation, the strength and hardness increases. Resins, metals, and inorganic salts can then further tailor the grade, physically and tribologically. Pure has an entire arsenal of carbon materials and the capability to further customize its offering, depending on market needs.

Pure offers three different families of silicon carbide materials: Chemical Vapor Reaction, which creates a silicon carbide surface on a graphite core, reaction bonded silicon carbides which contain free silicon, and self-sintered silicon carbides. In addition, we have combined our silicon carbide and carbon technologies to create a composite that has shown to increase the capability of hard-face combinations. These patented materials are regularly used in a variety of demanding applications where marginal lubrication at the interface is of concern.

The materials offered by Pure can be found in just about every place on, under, and above earth. From marine bearings and seals to household water pumps to rocket engine components and beyond, we have a material to fit your most demanding needs!
