Sinter-optimized α-Al₂O₃ for ceramic cutting tool inserts that hold edge under high-speed machining.
Cutting tool ceramics need extreme hardness, fracture toughness, and a fine microstructure to hold an edge under high-speed metal machining. Powder consistency drives tool life.
Strocera submicron α-Al₂O₃ reaches 98.05% of theoretical density by pressureless sintering at 1550 °C, with Vickers hardness 14.20 GPa and fracture toughness 3.89 MPa·m¹ᐟ² by Vickers indentation. Tool-specific specifications shared on request.
