New ceramic inserts for cast iron high speed machining

TZ120- TZ120 ceramic grade with high strength and excellent

wear resistance by adding ZrO2 to Al2O3 with high

oxidation resistance

- Each components are well dispersed to improve fracture

resistance and boundary wear resistance

- Suitable for dry roughing and finishing of special cast iron

(cylinder liner, etc.)

APPLICATION RANGE

TZ120 (Al2O3-ZrO2)

- Excellent wear resistance - High speed continuous turning of cast

iron without coolant

LX21 (Al2O3-TiC)

- High hardness and moderate fracture toughness

- General turning of cast iron

FX105 (Si3N4)

- Mechanical and thermal shock resistance- Interrupted & rough machining
