SPK® Ceramic Cutting Materials

SiAlON Ceramics for Machining Applications

α-/β-SiAlON cutting materials from CeramTec cover a wide range of applications for turning, milling and boring cast iron materials in continuous and intermittent cuts.

Gradient Characteristics

α-/β-SiAlON cutting ceramic grades are characterized by gradient characteristics that combine exceptional hardness and an extremely wear-resistant surface with a very tough insert core. The properties of α-/β-SiAlON cutting materials can be adjusted to the machining task depending on the grade’s focus.
