CERAMTUFF™ A4AS 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.
A4AS 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.
