All provided data are approximate values, depend on the application, environment and test conditions. Coating hardness HIT [GPa] measured by nano indentation according to ISO 14577. Hardness can be adapted to the application. Friction coefficient (dry) compared to the steel determined by ball-on-disc dry test with a steel sphere according to ASTM G99. During the running-in the indicated values may be exceeded. Maximum service temperature [° C] These are approximate values.
High resistance to abrasion: the fine-grained nanostructure gives the coating enormous toughness even under extreme operating conditions.
High thermal stability: AlCrO is versatile and recommended for processing in hard and dry machining (MQL) and high-speed cutting.
Protection against adhesive wear, AlCrO guarantees an exceptionally smooth and low-distortion surface quality.
AlCrO offers high performances in milling, threading and reaming operations of:
- steel alloys
- titanium alloys
- plastic molds and forming
