Where we are creating material change

At Haydale we can enhance the performance of material applications across a variety of industries.

We are a trusted partner to our customers, putting quality, performance and customer service at the heart of everything we do.

C-TUFF™ Ceramic Blends

C-TUFF™ ceramic composites are engineered blends of high-purity aluminum oxide and Silar® silicon carbide microfibers.  They are characterized by extreme hardness, outstanding compressive strength, and rigidity.  Parts made with C-TUFF™ materials offer exceptional fracture resistance, wear resistance, thermal shock resistance, and dimensional stability.  They are completely inert and can be used in the most demanding physical and chemical environments.

C-TUFF™ is offered in two grades:

  • HA9S: hot press-ready ceramic blend: Applications include high-performance ceramic cutting tools and ceramic wear parts requiring utmost fracture resistance.  Supplied without a binder for hot pressing.  Higher SiC whisker content for utmost fracture resistance. C-TUFF™ HA9S is a press-ready engineered blend of silicon carbide whisker and alumina used to produce high-performance ceramic cutting tools.  It is characterized by excellent fracture resistance, thermal dissipation, wear resistance, and thermal shock resistance.  HA9S has a high level of silicon carbide whisker to deliver the utmost performance.  It has exceptional fracture toughness and is suited for the most demanding applications.  HA9S uses Silar Silicon Carbide Whiskers.  We produce the highest purity, lowest particulate SiC whsikers out there.  We developed the original whisker reinforced cutting tool patents and have the best performing cutting tools on the market.
  • C-TUFF™ CT-8 is a dry press-ready engineered blend of silicon carbide whiskers and alumina used to produce highly wear resistant ceramics.  It is characterized by exceptional wear resistance and thermal and dimensional stability.  Applications include dies, pipe liners, nozzles, and other critical process equipment.  CT-8 has lower levels of SiC whisker to enable the product to be dry-pressed and sintered at atmospheric pressures.  No hot-pressing or pressure-assisted sintering is required.  Dry-pressing permits near-net shape parts to be produced with no green machining, reducing processing costs.  It can also be extruded.
